The function of most long noncoding RNAs (lncRNAs) is unknown. However, recent studies reveal important roles of lncRNAs in regulating cancer-related pathways. Human antisense lncRNA-NKX2-1-AS1 partially overlaps the NKX2-1/TTF1 gene within chromosomal region 14q13.3. Amplification of this region and/or differential expression of genes therein are associated with cancer progression. Herein we show higher levels of NKX2-AS1 and NKX2-1 in lung adenocarcinomas relative to non-tumor controls but no correlation between NKX2-1-AS1 and NKX2-1 levels across specimens, or with amplification of the 14q13.3 region, suggesting that NKX2-1-AS1 and NKX2-1 are independently regulated. Loss-and-gain of function experiments showed that ...


Intratumoral Sting Activation Sensitizes Poorly Immunogenic Cancers To Checkpoint Blockade Immunotherapy, Casey Ager 2018 The University of Texas MD ANderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Intratumoral Sting Activation Sensitizes Poorly Immunogenic Cancers To Checkpoint Blockade Immunotherapy, Casey Ager

UT GSBS Dissertations and Theses (Open Access)

Unprecedented durable tumor regression can be achieved in patients with checkpoint blockade immunotherapy, yet these responses are rare and are not observed in all tumor types. Castration resistant prostate cancer (CRPC) and pancreatic adenocarcinoma (PDAC) are two common lethal cancers that remain refractory to checkpoint blockade, requiring development of new therapeutic approaches to promote responsivity in patients with these diseases. Both CRPC and PDAC are characterized by an immunosuppressive tumor milieu rich in cells of the myeloid lineage, which regulate T cell activity in many ways independent of the coinhibitory receptor axis. We investigated whether activation of acute inflammatory signaling ...


Dual-Display Laparoscopic Laser Speckle Contrast Imaging For Real-Time Surgical Assistance, Jaepyeong Cha, Corey Zheng, Lung Wai Lau 2018 George Washington University - School of Medicine and Health Sciences

Dual-Display Laparoscopic Laser Speckle Contrast Imaging For Real-Time Surgical Assistance, Jaepyeong Cha, Corey Zheng, Lung Wai Lau

Pediatrics Faculty Publications

Laser speckle contrast imaging (LSCI) utilizes the speckle pattern of a laser to determine the blood flow in tissues. The current approaches for its use in a clinical setting require a camera system with a laser source on a separate optical axis making it unsuitable for minimally invasive surgery (MIS). With blood flow visualization, bowel viability, for example, can be determined. Thus, LSCI can be a valuable tool in gastrointestinal surgery. In this work, we develop the first-of-its-kind dual-display laparoscopic vision system integrating LSCI with a commercially available 10mm rigid laparoscope where the laser has the same optical axis as ...


Direct Crystal Formation From Micronized Bone And Lactic Acid: The Writing On The Wall For Calcium-Containing Crystal Pathogenesis In Osteoarthritis?, Anna A. Bulysheva, Nardos Sori, Michael P. Francis 2018 Old Dominion University

Direct Crystal Formation From Micronized Bone And Lactic Acid: The Writing On The Wall For Calcium-Containing Crystal Pathogenesis In Osteoarthritis?, Anna A. Bulysheva, Nardos Sori, Michael P. Francis

Bioelectrics Publications

Introduction

Pathological calcium-containing crystals accumulating in the joints, synovial fluid, and soft tissues are noted in most elderly patients, yet arthritic crystal formation remains idiopathic. Interestingly, elevated lactic acid and bone erosion are frequently among the comorbidities and clinical features of patients with highest incidence of crystal arthropathies. This work shows that bone particulates (modeling bone erosion) dissolve in lactic acid and directly generate crystals, possibly presenting a mechanism for crystal accumulation in osteoarthritis.

Methods and results

Micronized human bone (average particle size of 160 μm x 79 μm ) completely dissolved in lactic acid in 48 hours, and in synovial ...


Microrna-96 Promotes Schistosomiasis Hepatic Fibrosis In Mice By Suppressing Smad7, Xufeng Luo, Dongmei Zhang, Jun Xie, Qin Su, Xing He, Ruipu Bai, Guangping Gao, Weiqing Pan 2018 Second Military Medical University

Microrna-96 Promotes Schistosomiasis Hepatic Fibrosis In Mice By Suppressing Smad7, Xufeng Luo, Dongmei Zhang, Jun Xie, Qin Su, Xing He, Ruipu Bai, Guangping Gao, Weiqing Pan

UMass Center for Clinical and Translational Science Supported Publications

Infection with Schistosoma causes aberrant expression of host microRNAs (miRNAs), and normalizing the levels of dysregulated miRNAs can attenuate pathology. Here, we show that the host miRNA, miR-96, is markedly upregulated during the progression of hepatic schistosomiasis. We demonstrate that elevation of miR-96 induces hepatic fibrosis in infected mice by suppressing the expression of its target gene, Smad7. We show that infection with Schistosoma induces the expression of transforming growth factor beta1 (TGF-beta1), which in turn upregulates the expression of miR-96 through SMAD2/3-DROSHA-mediated post-transcriptional regulation. Furthermore, inhibition of miR-96 with recombinant adeno-associated virus 8 (rAAV8)-mediated delivery of Tough ...

Background: Tumorigenesis is driven by stem cell (SC) overpopulation. BecauseALDH is both a marker for SCs in many tissues and a key enzyme in retinoid acid (RA)signaling, we studied RA signaling in normal and malignant colonic SCs.Hypothesis: RA signaling regulates growth and differentiation of ALDH+ colonicSCs dysregulation of RA signaling contributes to SC overpopulation and colorectalcancer (CRC) development.Methods: We analyzed normal and malignant colonic tissues and CRC cell linesto see if retinoid receptors (RXR &RAR) are exclusively expressed in ALDH+ SCs,and if RA signaling changes during CRC development. We determined whether RAsignaling regulates cancer SC (CSC ...

Although imperfect, the structure of this journal and its publications are demonstrations of clinicians attempting to actualize the wisdom of these foundational thinkers. We need to leave examples and guideposts to the next generation of clinicians of how to fulfill this vision of being excellent clinicians, through both formal education and role modeling.

Reperfusion as a therapeutic intervention for acute myocardial infarction-induced cardiac injury itself induces further cardiomyocyte death. β-arrestin (βarr)-biased β-adrenergic receptor (βAR) activation promotes survival signaling responses in vitro; thus, we hypothesize that this pathway can mitigate cardiomyocyte death at the time of reperfusion to better preserve function. However, a lack of efficacious βarr-biased orthosteric small molecules has prevented investigation into whether this pathway relays protection against ischemic injury in vivo. We recently demonstrated that the pepducin ICL1-9, a small lipidated peptide fragment designed from the first intracellular loop of β2AR, allosterically engaged pro-survival signaling cascades in a βarr-dependent manner ...
