Disparities And Microbiome Affecting Liver Disease Progression, Ana I. Martinez Bulnes, Poornima Devi Shaji, Subhash C. Chauhan, Sheema Khan

Research Symposium

Non-alcoholic fatty liver disease (NAFLD) is a metabolic illness that encompasses a wide range of pathological states, from simple steatosis to steatohepatitis (NASH) to cirrhosis and hepatocellular carcinoma. NAFLD is the most prevalent liver disease in the world, accounting for 25% of all liver diseases cases. A high-fat diet, smoking, and alcohol consumption have all been proven to disrupt the balance of beneficial and possibly pathogenic bacterial species, resulting in intestinal dysbiosis. The prevalence of liver cancer (LC) among Latinos in South Texas remains greater than elsewhere in the United States, necessitating further research on population-specific risk factors and aggressive …

Novel Therapy Targeting Mutant-Krasg12d And Galectin-1 In Pancreatic Cancer, Ana I. Martinez Bulnes, Sheema Khan, Dan Ninroy, Poornima Devi Shaji, Swathi Holla, Murali M. Yallapu, Subhash C. Chauhan

Research Symposium

Introduction: Although, surgical resection and chemotherapy are the gold standard for treating Pancreatic Ductal Adenocarcinoma (PDAC), low patient survival rate remains the problem. The activating point mutation of the KRAS on codon-12 is present in 70–95% of PDAC cases and so far, no success has been achieved to inhibit KRAS. KRASG12D regulates cell proliferation, differentiation, apoptosis. Recent preliminary and published studies show high Galectin-1 (Gal-1) levels in both pancreatic cancer and stromal cells, which modulate tumor microenvironment and metastasis. Additionally, genetic deletion of gal1 inhibits metastasis and improves survival in KRAS mouse model of PDAC (1). Therefore, our objective is …

Unusual Inflammatory Presentation For Locally Advanced Papillary Thyroid Carcinoma, Ana I. Vargas, Samuel K. Snyder

Research Symposium

Background: Thyroid cancer usually presents as a thyroid nodule. If the history implies rapid growth of the nodule, new onset hoarseness or presence of ipsilateral cervical lymphadenopathy then it should raise concern for malignancy. Deep neck infection/inflammation has rarely been reported as initial presentation and these patients are potentially misdiagnosed.

Case Presentation: We present a 56-year-old male who comes to clinic for evaluation of left neck nodule. He started two weeks prior with sudden neck swelling associated with erythema and pain in his lower neck that caused choking sensation and swallowing discomfort, he was prescribed Bactrim and prednisone with improvement …

Research Symposium

Background: American trypanosomiasis is caused by parasite Trypanosoma cruzi, and it is considered a worldwide health problem. Current treatment consists of benznidazole and nifurtimox, which are not fully effective against both disease stages and have adverse effects. There is thus a need to find parasite-specific alternative treatments. Search of specific inhibitors of parasite-exclusive crucial enzymes is a known strategy. Trypanothione reductase (TR) enzyme is central in parasite’s redox system both for detoxification of reactive oxygen and nitrogen species as well as amino acid and nucleotide biosynthesis. Phenothiazine scaffold is known by pharmacologists as a very versatile structure and …

Modulation Of Pote-2 Expression By Ncrnas In Hepatocellular Carcinoma, Adithya Anilkumar, S. Lopez, Kyle Doxtater, Neeraj Chauhan, Sudhir Kotnala, Murali M. Yallapu, Vijian Dhevan, Subhash C. Chauhan, Manish Tripathi

Research Symposium

Background: Hepatocellular carcinoma (HCC) has one of the highest incidents and mortality rates within the Hispanic population of South Texas. The Surveillance, Epidemiology, and End Results (SEER) cancer registry reports a 20.3% 5-year relative survival rate upon HCC diagnoses, which decreases in advanced stage cancers. The disproportionate impact on the Hispanic community and poor prognostics makes the search for better diagnostic measures imperative. A major step in bridging the disparity in HCC occurrence is the identification of potential biomarkers aiding in HCC diagnosis, surveillance, and treatment. POTE ankyrin domain members have been recognized as key promotors of tumorigenesis. POTE-2, a …

Identification Of Tectorigenin As A Natural Pro-Hypoxia Compound: Implications In Modulation Of Cellular Differentiation And Senescence, Mallika Khurana, Renu Wadhwa, Sunil Kaul

Research Symposium

Background: Hypoxia, a suboptimal level of oxygen, evokes stress response in cells and activated hypoxia signaling has been largely established as a pro-metastasis and pro-angiogenic factor for tumor cells. On the other hand, age-related neurodegenerative disorders are characterized by hypoxic environment, accumulation of molecular garbage and induction of premature senescence. Several recent studies have reported anti-stress impact of the intermittent induction of hypoxia signaling in these cells.

Methods: Screening of a phytochemical library using Hypoxia Responsive Element (HRE) driven luciferase as a reporter was carried out to identify hypoxia-modulating phytochemicals. Activation of HIF-1a (master regulator of hypoxia signaling) was validated …

Molecular Event In Hrp Apoptosis, Laura Valdez

Research Symposium

Background: Human retinal pericytes (HRP) are contractile cells adjacent to and provide support for endothelial cells (EC) of capillaries, which are essential in the regulation of retinal vasculature. Early stages of DR are characterized by the loss of HRP, which leads to the development of advanced-stage pathology including angiogenesis. Although much is known about the etiology of DR, the apoptotic pathway that incites HRP loss remains unclear. Our preliminary studies reveal that monocyte-derived macrophages secrete TGF-β1, which induces the expression and secretion of a TGF-β1-Induced, pro-apoptotic BIGH3 protein (TGF-β–Induced Gene Human Clone 3) leading to apoptosis of HRP Eye, 30(12), …

Diaphragmatic Rupture Due To Closed Thoracobdominal Trauma: A Case Report, Juan Rosales Martínez, Manlio F. Lara Duck, Antonio Gutiérrez Sierra, Netzahualcoyotl Mayek Pérez

Research Symposium

Background. Diaphragmatic injuries (DI) represent less than 1% of traumatic injuries; they are a marker of severe trauma due to associated injuries, although they often go undiagnosed as they remain hidden. If undetected, delayed herniation and strangulation of the abdominal organs into the chest cavity will result as the defect in the diaphragm is not repaired. DI occurs from penetrating or blunt trauma. The former occurs in approximately 67% of cases; direct injury to the diaphragm caused by automobile accidents has been reported. The remaining third is due to falls and crush injuries. Blunt trauma causes larger tears, even bilateral. …

CRC is the 4^th most common cancer diagnosed among adults and the 2^ndleading cause of death from cancer. The ACS recommends that adults aged 45 years and older with an average risk of CRC undergo regular screening with either a high-sensitivity stool- based test or a structural (visual) examination, depending on patient preference and test availability. Screening with any one of multiple options is associated with a …

Determination Of Hfe C282y Mutation And Its Association With The Iron Status And Viral Load In Hiv Patients From Reynosa, Tamaulipas, Juan Carlos Hernández, Marisol Rosas Díaz, Esperanza Milagros García Oropesa, Santos Graciela Montemayor Beltrán, Juana Díaz García, Imelda Ramírez Puente

Research Symposium

Background: The HFE protein has a fundamental role in iron homeostasis, the HFE C282Y mutation prevents the specific function of the protein, causing greater intestinal absorption of iron and intracellular accumulation. The HIV virus causes a disease that attacks the cells of the immune system, mainly CD 4 T lymphocytes inducing their destruction and immunosuppression of the patient. Some viruses have the ability to disrupt cellular metabolic processes during their own replication, such is the case of HIV-1, which is involved in alteration of iron metabolism resulting in an overload of iron.

Methods: An exploratory, descriptive, cross-sectional and prolective study …

Hepatopulmonary Syndrome In A 22 Year Old Gentleman With Liver Cirrhosis, Blesset Alexander, Joseph Caporusso, Priyasha Suri

Research Symposium

Background: Hepatopulmonary syndrome is a severe complication of end-stage liver disease characterized by triad of liver disease, intrapulmonary vascular dilatation, and arterial hypoxemia. Although the pathogenesis is not completely understood, pulmonary vascular dilatation occurs due to imbalance between vasodilators and vasoconstrictors. Liver injury is thought to increase endothelin production and cause bacterial translocation, causing increased nitric oxide production, causing vasodilation of pulmonary vasculature. History and physical examination are important in leading the physician to the correct diagnosis as the majority of these patients present with non-specific clinical manifestations and imaging. Identification of specific physical exam findings is important in not …

That Which Keeps On Giving - A Case Of Class Iv Diffuse Proliferative Lupus Nephritis In A Hispanic Woman With Underlying Systemic Lupus Erythematosus, Josenny L. Rodriguez-Paez, Christine E. Loftis, Rosa White-Guedez

Research Symposium

Background: Glomerulonephritis is the primary cause of morbidity and mortality of systemic lupus erythematosus (SLE). Lupus nephritis is characterized by immune complex deposition in the mesangium leading to complement activation and hypocomplementemia. Studies show that up to 60% of adults with lupus develop renal involvement and it has been well established that Hispanic patients show poorer outcomes than Caucasians despite advances in treatment. Preserved kidney function with new-onset proteinuria should raise clinical suspicion for acute lupus nephritis. Further evaluation with a kidney biopsy is paramount in establishing a diagnosis, helping to define treatment strategy, and determining response to treatment.
