Glutaminase - A Potential Target For Cancer Treatment, Josephine Anthony, Sureka Varalakshmi, Ashok Kumar Sekar, Nalini Devarajan, Balamurugan Janakiraman, Rajendran Peramaiyan

BioMedicine

The overexpression of glutaminase is reported to influence cancer growth and metastasis through glutaminolysis. Upregulation of glutamine catabolism is recently recognized as a critical feature of cancer, and cancer cells are observed to reprogram glutamine metabolism to maintain its survival and proliferation. Special focus is given on the glutaminase isoform, GLS1 (kidney type glutaminase), as the other isoform GLS2 (Liver type glutaminase) acts as a tumour suppressor in some conditions. Glutaminolysis linked with autophagy, which is mediated via mTORC1, also serves as a promising target for cancer therapy. Glutamine also plays a vital role in maintaining redox homeostasis. Inhibition of …

The size of the human head is highly heritable, but genetic drivers of its variation within the general population remain unmapped. We perform a genome-wide association study on head size (N = 80,890) and identify 67 genetic loci, of which 50 are novel. Neuroimaging studies show that 17 variants affect specific brain areas, but most have widespread effects. Gene set enrichment is observed for various cancers and the p53, Wnt, and ErbB signaling pathways. Genes harboring lead variants are enriched for macrocephaly syndrome genes (37-fold) and high-fidelity cancer genes (9-fold), which is not seen for human height variants. Head size …

Development Of A Computational Model To Investigate Pathways And The Effects Of Treatment In Fanconi Anemia, Sabrina Kellett

Biological Sciences Undergraduate Honors Theses

Fanconi Anemia (FA) is a rare type of anemia that is not easily studied and can have very detrimental effects. This disease compromises the bone marrow, resulting in decreased hemopoiesis. Symptoms of FA also include abnormalities in the brain and spinal cord, incorrect formation of the kidneys, abnormal formation of the heart and lungs, and a dramatically increased risk of developing cancer. FA can be caused by various mutations in any of the 22 genes that encode for proteins involved in what is called the FA DNA repair pathway. In healthy individuals, this pathway specifically repairs interstrand cross-links (ICLs) recognized …

Interactions Between Silica And Titanium Nanoparticles And Oral And Gastrointestinal Epithelia: Consequences For Inflammatory Diseases And Cancer, Cassio Luiz Coutinho Almeida-Da-Silva, Leticia Ferreira Cabido, Wei Chun Chin, Ge Wang, David M. Ojcius, Changqing Li

All Dugoni School of Dentistry Faculty Articles

Engineered nanoparticles (NPs) composed of elements such as silica and titanium, smaller than 100 nm in diameter and their aggregates, are found in consumer products such as cosmetics, food, antimicrobials and drug delivery systems, and oral health products such as toothpaste and dental materials. They may also interact accidently with epithelial tissues in the intestines and oral cavity, where they can aggregate into larger particles and induce inflammation through pathways such as inflammasome activation. Persistent inflammation can lead to precancerous lesions. Both the particles and lesions are difficult to detect in biopsies, especially in clinical settings that screen large numbers …

Understanding The Role Of Ano1 In Oral Cancer, Mallary Forrest

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2008, the gene ANO1 was discovered to encode a calcium activated chloride channel. This gene is located on the 11q13 locus, a locus that is commonly amplified in many cancers including cancer of the head and neck. ANO1 is situated in close proximity to genes associated with growth and apoptosis. As rapid proliferation and lack of apoptosis are hallmark characteristics of cancer, growth factors and apoptosis mediators are expected to be altered in cancer. But what does a calcium activated chloride channel have to contribute to cancer’s pathogenesis? Is it an active gene in cancer progression or is it …

A Multilevel And Spatial Analysis Of Oral And Pharyngeal Cancer In South Carolina, Deborah M. Hurley

Tobacco Smoke Carcinogens Induce Dna Repair Machinery Function Loss: Protection By Carbon Nanotubes, Anukriti Dhasmana, Anupam Dhasmana, Hobani Yahya H, Abdullah Farasani, Mahmoud Habibullah, Freah L. Alshammary, Saif Khan, Shafiul Haque, Mohtashim Lohani

School of Medicine Publications and Presentations

Purpose: DNA damage is a continuous process occurring within the cells caused by intrinsic and extrinsic factors, but it gets repaired regularly. If the DNA repair process is faulty, the incidences of damages/mutations can accumulate in cells resulting in cell transformation. It is hypothesized that the negative variations in DNA repair pathways in even at one point viz. genetic, translational or posttranslational stage may fairly be crucial for the beginning and development of carcinogenesis. Therefore, we investigated the potential of tobacco specific nitrosamines (TSNs) related carcinogens to interact with the enzymes involved in DNA repair mechanisms in the current study. …

Expanding The Capacity Of Rural Cancer Care With Teleoncology, Jason Semprini

Online Journal of Rural Research & Policy

Background: In the United States, 6 of the 25 leading causes of death stem from site-specific cancers, resulting in over 1.7 million deaths annually. Yet, this burden is not evenly distributed. While the incidence of cancer is significantly higher in urban areas, rural regions face higher rates of cancer mortality. Identifying the factors contributing rural cancer disparities can facilitate more effective and feasible policy solutions.’

Problem Definition: Rural Americans are geographically isolated from high-quality cancer services and face systemic barriers to NCI designated comprehensive cancer centers. Given this disparity, rural Americans have failed to fully realize the benefits of expanded …

Evaluating The Utility Of Protein Biomarker, S100a7, And Diagnostic Test, Straticyte, In Predicting The Progression Of Oral Dysplasia, Lachlan Mclean

Electronic Thesis and Dissertation Repository

Five-year survival of oral cancer has remained relatively unchanged despite advancements in treatment, mostly because diagnosis is often made at an advanced stage of disease. The progression of dysplasia to oral cancer often follows a stepwise progression. Histopathology is considered the ‘gold standard’ for diagnosing dysplasia and lesions at a high risk of progression to oral cancer, but lends itself to subjectivity. The protein biomarker, S100A7, in oral dysplasia and squamous cell carcinoma has shown some predictive value for the transformation of dysplasia to cancer. Straticyte, a diagnostic test utilizing S100A7 to predict the probability of progression of oral dysplasia …

Effects Of Visit Frequency On Swallowing Function During Organ Preservation For Head And Neck Cancer, Mathew Blaine Vansant

LSU Doctoral Dissertations

Chemoradiotherapy is not without risk of injury to the muscles and nerves associated with swallowing function. Current research supports the use of prophylactic behavioral swallowing exercise in the HNC population, however, wide variations in swallowing treatment methodologies exist and no optimal SLP-patient visit frequency has been established. In addition, poor patient adherence to swallowing exercise appears prevalent. The current study explored the impact of speech language pathologist (SLP)-patient contact time, adherence to prophylactic behavioral swallowing exercises, and explored effects of exercise intensity on immediate post-radiation swallowing outcomes. Groups included a high frequency group (5 weekly SLP-patient visits, n = 15), …

The Experience Of Qigong Among Women Cancer Survivors, Jennifer Sveund

Antioch University Dissertations & Theses

Research has shown that qigong can be beneficial for a variety of health related conditions; However, evidence suggests that in the United States, a lack of well designed clinical trials limits the efficacy of qigong in the context of cancer treatment. Research has indicated that careful consideration should be given to the design of randomized control trials using qigong due to the conflicting philosophical methodologies. In the United States, qigong has been under investigated, particularly lacking are qualitative inquiries into qigong use and cancer survivorship. This study is an interpretative phenomenological inquiry that sought to understand women’s experience of qigong …

Psychological Aspects Of Head And Neck Cancer, Katherine Rieke

Theses & Dissertations

Patients with head and neck cancer may be at increased risk for depression diagnosis when compared to other cancer sites, both before and after their cancer diagnosis. Behavioral risk factors for head and neck cancers, including tobacco and alcohol use, may be indicative of depression before cancer diagnosis. Further, head and neck cancers and their treatments can cause serious morbidity among patients, including physical disfigurement and loss of function. Additionally, these cancers are often accompanied by social stigma, personal shame, and guilt. While there is a significant body of research examining depression in this cancer population, there are still several …

Surface-Initiated Polymerizations For The Rapid Sorting Of Rare Cancer Cells, Jacob L. Lilly

Theses and Dissertations--Chemical and Materials Engineering

Cancer metastasis directly accounts for an estimated 90% of all cancer related deaths and is correlated with the presence of malignant cells in systemic circulation. This observed relationship has prompted efforts to develop a fluid biopsy, with the goal of detecting these rare cells in patient peripheral blood as surrogate markers for metastatic disease as a partial replacement or supplement to tissue biopsies. Numerous platforms have been designed, yet these have generally failed to support a reliable fluid biopsy due to poor performance parameters such as low throughput, low purity of enriched antigen positive cells, and insufficiently low detection thresholds …
