The Relationship Between Inflammatory Diet Score And Cancer Outcomes: Systematic Review And Meta-Analysis, Eric Han

Honors Undergraduate Theses

Cancer remains one of the most prevalent diseases in the United States and a leading cause of death. Large prospective studies have found significant correlations between dietary intake and cancer. Chronic inflammation promotes pro-cancer inflammatory environments promoting the formation and growth of tumors while preventing effective anti-tumor responses. Nutrition can impact inflammation, with the intake of certain food items increasing biomarkers for systemic inflammation thus, the objective of this research was to explore the relationship between inflammatory diet score measured by the Dietary Inflammatory index and all-cause mortality, cancer-specific mortality, and cancer recurrence among cancer survivors.

Epithelial Memory Of Resolved Inflammation Limits Tissue Damage While Promoting Pancreatic Tumorigenesis, I-Lin Ho

Dissertations and Theses (Open Access)

Inflammation is a major risk factor for pancreatic ductal adenocarcinoma. When occurring in the context of pancreatitis, mutations of KRAS accelerate tumor development. We discovered that long after its complete resolution, a transient inflammatory event primes pancreatic epithelial cells to subsequent transformation by oncogenic KRAS. Upon recovery from acute inflammation, epithelial cells of the pancreas display an enduring adaptive response associated with sustained transcriptional and epigenetic reprogramming. Such adaptation enables the prompt reactivation of acinar-to-ductal metaplasia (ADM) upon subsequent inflammatory events, thus efficiently limiting tissue damage via rapid decrease of zymogen production. We propose that since activating mutations of KRAS …

Mitochondrial Transfer From Mesenchymal Stem Cells Improves Neuronal Metabolism After Oxidant Injury In Vitro: The Role Of Miro1, Nancy Tseng, Scott C Lambie, Christopher Q Huynh, Bridget Sanford, Manisha Patel, Paco S Herson, D Ryan Ormond

Faculty, Staff and Students Publications

Stroke-induced cerebral ischemia is a major cause of death and disability. The disruption of blood flow results in neuronal and glial cell death leading to brain injury. Reperfusion restores oxygen to the affected tissue, but can also cause damage through an enhanced oxidative stress and inflammatory response. This study examines mitochondrial transfer from MSC to neurons and the role it plays in neuronal preservation after oxidant injury. We observed the transfer of mitochondria from MSC to mouse neurons in vitro following hydrogen peroxide exposure. The observed transfer was dependent on cell-to-cell contact and led to increased neuronal survival and improved …

Role Of Ceramide-1 Phosphate In Regulation Of Sphingolipid And Eicosanoid Metabolism In Lung Epithelial Cells, Brittany A. Dudley

USF Tampa Graduate Theses and Dissertations

Ceramide 1-Phosphate (C1P) is a sphingolipid metabolite which plays a large role in inflammation, cell survival and proliferation¹. C1P is known to have both pro- and anti-apoptotic roles in lung cancer cells, governed by ceramide kinase (CERK), upstream of precursor ceramide (Cer)². Previous work reveals C1P serves as the liaison between sphingolipid and eicosanoid synthesis, by decreasing the dissociation rate of group IVA cytosolic PLA₂ (cPLA_2α) from the Golgi membrane, C1P directly activates this phospholipase for downstream eicosanoid synthesis and subsequent inflammatory response³. CERK has been discovered to modulate eicosanoid synthesis, …

Recombinant Human Proteoglycan-4 Mediates Interleukin-6 Response In Both Human And Mouse Endothelial Cells Induced Into A Sepsis Phenotype, Holly A. Richendrfer, Mitchell M. Levy, Khaled A. Elsaid, Tannin A. Schmidt, Ling Zhang, Ralph Cabezas, Gregory D. Jay

Pharmacy Faculty Articles and Research

Objectives:

Sepsis is a leading cause of death in the United States. Putative targets to prevent systemic inflammatory response syndrome include antagonism of toll-like receptors 2 and 4 and CD44 receptors in vascular endothelial cells. Proteoglycan-4 is a mucinous glycoprotein that interacts with CD44 and toll-like receptor 4 resulting in a blockade of the NOD-like receptor pyrin domain-containing-3 pathway. We hypothesized that endothelial cells induced into a sepsis phenotype would have less interleukin-6 expression after recombinant human proteoglycan 4 treatment in vitro.

Design:

Enzyme-linked immunosorbent assay and reverse transcriptase-quantitative polymerase chain reaction to measure interleukin-6 protein and gene expression.

Setting: …

Multi-Generational Effects Of ∆9-Tetrahydrocannabinol Exposure On Gene Expression In Liver Tissue, Kayla Lovitt

Honors Theses

Cannabis is the most commonly used, cultivated, and trafficked illicit drug worldwide. Increased availability and acceptance of cannabis and cannabinoid-containing products provide the necessity for understanding how these substances influence aging. In this study, zebrafish (Danio rerio) were exposed to concentrations of Δ⁹-tetrahydrocannabinol (THC) (0.08, 0.4, 2 µM) during embryonic-larval development, the effects on aging were measured 30 months later and in the offspring of the exposed fish (F1 generation. We observed results indicating a biphasic and hormetic effect. Treatment with the lowest concentration of THC significantly increased egg production, while higher concentrations resulted in impaired …

Cd11b+ Depletion Of Bone Marrow Derived Macrophages Negatively Affects Bone Fracture Healing, Sarah Hozain

Seton Hall University Dissertations and Theses (ETDs)

Hematoma formation and inflammation occurs during the beginning stages of fracture repair, which require the presence of innate cells such as macrophages. Macrophages are subdivided into proinflammatory, M1, or anti-inflammatory, M2, phenotypes with different functions, cytokine profiles, and surface markers. In this study, in vitro and in vivo models were used to deplete M1 macrophages, using Mac-1 Sap conjugated antibody (Mac1SAP), to determine the effects on fracture healing. In vitro study, primary macrophages isolated from mice femoral bone marrow were harvested and differentiated into M1 macrophages (+LPS), M2 macrophages (+IL-4), or undifferentiated then treated with either vehicle or 10pM Mac1SAP. …

Cold-Inducible Rna Binding Protein (Cirp) Impedes Proliferation And Inflammation In The Pymt Mouse Model For Breast Cancer, Daniel Albino Lujan

Biomedical Sciences ETDs

RNA binding proteins (RBPs) regulate gene expression by controlling mRNA export, translation, and stability. When altered, some RBPs allow cancer cells to grow, survive, and metastasize. Cold-inducible RNA binding protein (CIRP) is overexpressed in a subset of breast cancers, induces proliferation in breast cancer cell lines, and inhibits apoptosis. We generated a transgenic mouse model overexpressing human CIRP in the mammary epithelium to ask if it plays a role in mammary gland development. We also assessed the effects of CIRP on breast tumorigenesis using breeding crosses with the PyMT mouse model for breast cancer. CIRP decreased proliferation at the lactational …

Functional And Transcriptomic Characterization Of Cisplatin-Resistant Ags And Mkn-28 Gastric Cancer Cell Lines, Barbara Mora-Lagos, Irene Cartas-Espinel, Ismael Riquelme, Alyssa C. Parker, Stephen R. Piccolo, Tamara Viscarra, Maria Elena Reyes, Louise Zanella, Kurt Buchegger, Carmen Ili, Priscilla Brebi

Faculty Publications

Gastric cancer (GC) is a significant cancer-related cause of death worldwide. The most used chemotherapeutic regimen in GC is based on platinum drugs such as cisplatin (CDDP). However, CDDP resistance reduces advanced GC survival. In vitro drug-resistant cell model would help in the understanding of molecular mechanisms underlying this drug-resistance phenomenon. The aim of this study was to characterize new models of CDDP-resistant GC cell lines (AGS R-CDDP and MKN-28 R-CDDP) obtained through a stepwise increasing drug doses method, in order to understand the molecular mechanisms underlying chemoresistance as well as identify new therapeutic targets for the treatment of GC. …

The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine

Theses and Dissertations

Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …

Anti-Inflammatory Effects Of Cruciferous And Apiaceous Vegetables In C57bl/6j Mice Colon, Rosa Moreno Narvaez

Graduate Theses and Dissertations

Previous studies have demonstrated chemo-preventive potential of cruciferous and apiaceous vegetables against colon cancer. Colon inflammation is one condition closely related with colon cancer initiation. Therefore, we wanted to compare if total western diet (TWD) was as pro-inflammatory as died-induced obesity (DIO) and a better dietary model for human conditions, and determine if diet supplementation with cruciferous (broccoli, watercress and cabbage) or apiaceous vegetables (celery and parsnip) could reduce dietary inflammation, and which vegetable was more effective.

Male CBL57/6J mice were fed chow for seven days, on day eight, mice were assigned to one of the following diets: American Institute …

The Cxcr2-Dependent Role Of Cancer-Associated Fibroblasts In Pancreatic Ductal Adenocarcinoma, Mohammad Awaji

Theses & Dissertations

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer, the fourth leading cause of cancer-related deaths in the USA with over 40,000 deaths per year. Unlike other major cancer types, the progress in dealing with PDAC is plodding, attributed mainly to the asymptomatic nature of the disease, the late diagnosis and the ineffectiveness of current therapies. A better understanding of the biology of the disease could permit the discovery of novel diagnostic and therapeutic tools. With that in mind, we present this dissertation that investigates the tumor-stromal interaction underlined by genetic alterations and inflammation. PDAC develop as …

Adipose-Derived Autotaxin Regulates Inflammation And Steatosis Associated With Diet-Induced Obesity, J. Anthony Brandon, Maria Kraemer, Julia Vandra, Suchismita Halder, Margo F. Ubele, Andrew J. Morris, Susan S. Smyth

Gill Heart & Vascular Institute Faculty Publications

Autotaxin (ATX) is a secreted enzyme that generates the bioactive lipid lysophosphatidic acid (LPA). We generated mice with global inducible post-natal inactivation or adipose-specific loss of the Enpp2 gene encoding ATX. The animals are phenotypically unremarkable and exhibit differences in adipocyte size and adipose tissue expression of inflammatory genes after high fat feeding without gross differences in fat distribution or body mass. Surprisingly, both models of Enpp2- deficiency exhibited marked protection from high fat diet-induced hepatic steatosis. This phenotype was not associated with differences in dietary fat absorption but may be accounted for by differences in hepatic expression of …

Anatomy and Cell Biology Publications

The brain regulates physiological functions integral to survival. However, the insight into brain neuronal regulation of peripheral immune function and the neuromediator systems and pathways involved remains limited. Here, utilizing selective genetic and pharmacological approaches, we studied the role of forebrain cholinergic signaling in the regulation of peripheral immune function and inflammation. Forebrain-selective genetic ablation of acetylcholine release and vagotomy abolished the suppression of serum TNF by the centrally-acting cholinergic drug galantamine in murine endotoxemia. Selective stimulation of acetylcholine action on the M1 muscarinic acetylcholine receptor (M1 mAChR) by central administration of the positive allosteric modulator benzyl quinolone carboxylic acid …

The Balance Between Prostaglandin E2 Ep3 And Ep4 Receptors Determines Severity Of Cardiac Damage In Myocardial Infarction And An Angiotensin Ii-Induced Model Of Hypertension, Timothy Dean Bryson

Wayne State University Dissertations

According to the center for disease control about 610,000 people die every year in the United States from heart disease, of which, coronary heart disease is the most common form. One major risk factor for heart attack is hypertension, which affects nearly half of all Americans [472, 473]. PGE2 plays an important role in regulating cardiovascular function and mediating inflammation, both of which contribute to the development of hypertension and/or heart disease. Prostaglandin E2 can act as a vasodilator or vasoconstrictor depending on which of its receptor subtypes are activated.

In general, activation of the EP1 and EP3 receptors is …

Critical Physicochemical Properties For Nanoparticle Toxicity: Impact Of Surface Coating And Size On Particle-Induced Cell Transformation And Inflammatory Response, Tiffany Kornberg

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nanoparticles, which measure 100 nm in at least one dimension, have surged in development, production, and use for a wide range of applications. However, the rapid pace of development for these emerging materials with unclear/unknown toxicity profiles makes it difficult to adequately assess health risk associated with exposure. One critical obstacle which limits scientific research to fill these critical knowledge gaps is the lack of accurate and predictive models for nanotoxicology studies, particularly those which involve occupationally relevant exposure scenarios (pulmonary exposure to low dose of particles in the circulating air). Typically, animal models are used to assess potential systemic …

Dissecting The Molecular Mechanism Of Early Tumor Dissemination In Non-Small Cell Lung Cancer, Xingtong Liu

Dissertations and Theses (Open Access)

Lung cancer is the most common cause of cancer related death in the United States and worldwide. It has been shown that 30%-55% of patients with early stages of non-small cell lung cancer (NSCLC) developed and died of recurrence after curative resection, suggesting that tumor cell dissemination occurred early in those patients before surgery. However, molecular evidence, underline mechanisms and risk factors for the NSCLC relapse remain largely unknown. Addressing these questions will be critical for the development of strategies to stratify the risk of recurrence and approaches to reduce these risks. My thesis focused on dissecting the molecular basis …

5-Lipoxygenase (5-Lox)-5-Lipoxygenase Activating Protein (Flap)-Nanodisc Complex: A Model For The 5-Lox-Flap Interaction, Erin Elizabeth Schexnaydre

LSU Doctoral Dissertations

Leukotrienes (LT) are lipid mediators of the inflammatory response that play important roles in diseases such as asthma and atherosclerosis. Leukotriene A4 (LTA₄) is synthesized from arachidonic acid (AA) by 5-lipoxygenase (5-LOX) with the help of 5-lipoxygenase activating protein (FLAP), a trimeric nuclear transmembrane protein. Exactly how 5-LOX and FLAP interact is not well understood, however FLAP is essential for the production of leukotrienes in vivo. I used nanodiscs (NDs), engineered membrane systems, as a tool to study the 5-LOX-FLAP interaction. FLAP was incorporated into NDs with a phospholipid composition to mimic of the nuclear membrane. Structural features …

Pkc-Dependent Phosphorylation Of Munc18a At Ser313 In Activated Rbl-2h3 Cells, Pratikshya Adhikari, Hao Xu

Faculty Publications

Protein Kinase C (PKC) regulates the release of pro-inflammatory compounds from IgE/antigen-activated mast cells by unknown mechanisms. In this study, we show for the first time that PKC inhibitor Ro-03-0432, which inhibits RBL-2H3 exocytosis/degranulation in a concentration-dependent fashion, prevents the phosphorylation of membrane fusion factor Munc18a at Ser 313. Our study provides fresh evidence that PKC-dependent protein phosphorylation may contribute to the intricate regulation of mast cell degranulation by directly targeting the fusion factors.

Modulation Of Cytokine Signaling In Optic Nerve Regeneration In Xenopus Laevis, Rupa Priscilla Choudhary

Legacy Theses & Dissertations (2009 - 2024)

The axons of the optic nerve, like other central nervous system (CNS) axons, tend to lose their capacity to regenerate following an injury in adult amniotes, but these axons are able to regenerate throughout life in anamniotes. In mammals, optic axon regeneration is promoted by inhibiting the increased expression in retinal ganglion cells of a cytokine signaling molecule, Suppressor of Cytokine Signaling 3 (SOCS3), that accompanies injury. In animals capable of regeneration, SOCS3 mRNA expression also increases dramatically in retinal ganglion cells after optic nerve injury, but somehow this increase is insufficient to block regeneration. To gain insights into how …

Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks

Theses and Dissertations

Atherosclerotic cardiovascular disease (CVD) is hallmarked by inflammatory immune activation, particularly by the induction of a response by monocytes. Classical (CD14⁺⁺CD16^-) are anti-inflammatory mediators under homeostatic conditions, while intermediate (CD14⁺⁺CD16⁺) and non-classical (CD14^LowCD16⁺⁺) monocytes promote inflammation following activation. Monocyte activation and functionality is dependent upon receptor expression and ligand production by a variety of cells, including monocytes. Alterations in the expression of surface receptors often have a direct impact upon monocyte function, such as the increased pro-inflammatory cytokine production in response to activation that accompanies elevated CD14 expression …

Potential Anticancer Effect Of Prostratin Through Sik3 Inhibition, Dalal Alotaibi, Suneetha Amara, Terrance L. Johnson, Venkataswarup Tiriveedhi

Biology Faculty Research

Prostratin, a phorbol ester natural plant compound, has been demonstrated to exert an anti‑retroviral effect through activation of latent cluster of differentiation (CD)4+T lymphocytes and inhibition of viral entry into the cell through downregulation of chemokine receptor type 4 (CXCR4) expression. However, the potential effect of prostratin on cancer is yet to be defined. As CXCR4 is well known to induce cancer migration, it was hypothesized that prostratin induces an anti‑cancer effect through inhibition of CXCR4 expression. The authors previously demonstrated that high stimulating conditions (sub‑minimal IL‑17, 0.1 ng/ml, synergized with high salt, Δ0.05 M NaCl) promote breast cancer cell …

Critical Role Of Sik3 In Mediating High Salt And Il-17 Synergy Leading To Breast Cancer Cell Proliferation, Suneetha Amara, Ciera Majors, Bipradas Roy, Salisha Hill, Kristie L. Rose, Elbert L. Myles, Venkataswarup Tiriveedhi

Biology Faculty Research

Chronic inflammation is a well-known precursor for cancer development and proliferation. We have recently demonstrated that high salt (NaCl) synergizes with sub-effective interleukin (IL)-17 to induce breast cancer cell proliferation. However, the exact molecular mechanisms mediating this effect are unclear. In our current study, we adopted a phosphoproteomic-based approach to identify salt modulated kinase-proteome specific molecular targets. The phosphoprotemics based binary comparison between heavy labelled MCF-7 cells treated with high salt (Δ0.05 M NaCl) and light labelled MCF-7 cells cultured under basal conditions demonstrated an enhanced phosphorylation of Serine-493 of SIK3 protein. The mRNA transcript and protein expression analysis of …

Macrophages Are Necessary For Epimorphic Regeneration In African Spiny Mice, Jennifer Simkin, Thomas R. Gawriluk, John C. Gensel, Ashley W. Seifert

Biology Faculty Publications

How the immune system affects tissue regeneration is not well understood. In this study, we used an emerging mammalian model of epimorphic regeneration, the African spiny mouse, to examine cell-based inflammation and tested the hypothesis that macrophages are necessary for regeneration. By directly comparing inflammatory cell activation in a 4 mm ear injury during regeneration (Acomys cahirinus) and scarring (Mus musculus), we found that both species exhibited an acute inflammatory response, with scarring characterized by stronger myeloperoxidase activity. In contrast, ROS production was stronger and more persistent during regeneration. By depleting macrophages during injury, we demonstrate …

Role Of Endothelin Axis In Pancreatic Tumor Microenvironment, Suprit Gupta

Theses & Dissertations

Endothelins (ETs) are a family of three 21 amino-acid vasoactive peptides ET-1, ET-2 and ET-3 that mediate their effects via two G-protein couple receptors ET_AR and ET_BR which are expressed on various cell types. Apart from their physiological role in vasoconstriction, there is emerging evidence supporting the role of endothelin axis (ET-axis) in cancer. Due to the expression of ET receptors on various cell-types, ET-axis can exert pleotropic effects and contribute to various aspects of cancer pathobiology. Several studies have provided a fragmented picture of the diverse roles or ET-axis in various tumors. However, the comprehensive …

Increased Ros Production In Non-Polarized Mammary Epithelial Cells Induces Monocyte Infiltration In 3d Culture, Linzhang Li, Jie Chen, Gaofeng Xiong, Daret K. St. Clair, Wei Xu, Ren Xu

Markey Cancer Center Faculty Publications

Loss of epithelial cell polarity promotes cell invasion and cancer dissemination. Therefore, identification of factors that disrupt polarized acinar formation is crucial. Reactive oxygen species (ROS) drive cancer progression and promote inflammation. Here, we show that the non-polarized breast cancer cell line T4-2 generates significantly higher ROS levels than polarized S1 and T4R cells in three-dimensional (3D) culture, accompanied by induction of the nuclear factor κB (NF-κB) pathway and cytokine expression. Minimizing ROS in T4-2 cells with antioxidants reestablished basal polarity and inhibited cell proliferation. Introducing constitutively activated RAC1 disrupted cell polarity and increased ROS levels, indicating that RAC1 is …

Effect Of Endoplasmic Reticulum Stress On Vascular Smooth Muscle Cells And Its Regulation Of Sm22Α, Neeraja Priyanka Annam

Wayne State University Dissertations

Background: The vascular smooth muscle cells(VSMC) possess the ability to differentiate into a synthetic phenotype in response to stress. This phenotypic modulation may be accompanied by inflammatory or osteogenic response in chronic stress. The synthetic state is characterized by low levels of contractile markers unlike the differentiated state.

Hypothesis: Endoplasmic reticulum (ER) stress causes phenotypic modulation in VSMCs leading to apoptosis. Many transcription factors induced by ER stress contribute to the downregulation of Sm22α. Perturbation in cytoskeletal dynamics exacerbates the ER stress response.

Methods: Ex-vivo culture was used to establish importance of Sm22 in ER stress. In vitro analysis was …

Hdac6 Inhibition Prevents Tnf-Α-Induced Caspase 3 Activation In Lung Endothelial Cell And Maintains Cell-Cell Junctions, Jinyan Yu, Mengshi Ma, Zhongsen Ma, Jian Fu

Center for Research on Environmental Disease Faculty Publications

Pro-inflammatory mediators such as TNF-α induce caspase activation in endothelial cells, which leads to degradation of cellular proteins, induction of apoptotic signaling, and endothelial cell dysfunction. New therapeutic agents that can inhibit caspase activation may provide protection against inflammatory injury to endothelial cells. In the present study, we examined the effects of selective histone deacetylase 6 (HDAC6) inhibition on TNF-α induced caspase 3 activation and cell-cell junction dysfunction in lung endothelial cells. We also assessed the protective effects of HDAC6 inhibition against lung inflammatory injury in a mouse model of endotoxemia. We demonstrated that selective HDAC6 inhibition or knockdown of …

Nfat5/Stat3 Interaction Mediates Synergism Of High Salt With Il-17 Towards Induction Of Vegf-A Expression In Breast Cancer Cells, Suneetha Amara, Dalal Alotaibi, Venkataswarup Tiriveedhi

Biology Faculty Research

Chronic inflammation has been considered an important player in cancer proliferation and progression. High salt (sodium chloride) levels have been considered a potent inducer of chronic inflammation. In the present study, the synergistic role of high salt with interleukin (IL)‑17 towards induction of the inflammatory and angiogenic stress factor vascular endothelial growth factor (VEGF)‑A was investigated. Stimulation of MCF-7 breast cancer cells with high salt (0.2 M NaCl) and sub‑minimal IL‑17 (1 ng/ml) enhanced the expression of VEGF-A (2.9 and 2.6-fold, respectively, P<0.05) compared with untreated cells. Furthermore, co‑treatment with both high salt and sub‑minimal IL‑17 led to a 5.9‑fold increase in VEGF‑A expression (P<0.01), thus suggesting a synergistic role of these factors. VEGF‑A promoter analysis and specific small interfering RNA knock‑down of transcription factors revealed that high salt induced VEGF‑A expression through nuclear factor of activated T‑cells (NFAT)5, while IL‑17 induced VEGF‑A expression via signal transducer and activator of transcription (STAT)3 signaling mechanisms. Treatment of normal human aortic endothelial cells with the supernatant of activated MCF‑7 cells enhanced cell migration and induced expression of migration‑specific factors, including vascular cell adhesion protein, β1 integrin and cluster of differentiation 31. These data suggest that high salt levels synergize with pro‑inflammatory IL‑17 to potentially induce cancer progression and metastasis through VEGF‑A expression. Therefore, low‑salt diet, anti‑NFAT5 and anti‑STAT3 therapies may provide novel avenues for enhanced efficiency of the current cancer therapy.
