Research Symposium

Pancreatic cancer (PanCa) is a third leading cause of cancer related deaths in US. Unlike other cancers, PanCa is highly resistant to TNF-related apoptosis-inducing ligand (TRAIL) that emerges as one of the most-promising therapy in clinical trials. Our group has previously identified microRNA-145 (miR-145) is downregulated in PanCa, the restoration of which inhibits tumor growth and enhances gemcitabine sensitivity. In this study, we have observed that miR-145 restoration in PanCa cells renders them sensitive to TRAIL treatment. Therefore, we have engineered unique superparamagnetic nanoparticles (SPs) for co-delivering miR-145 and TRAIL in PanCa for improving their therapeutic response to TRAIL. The …

Antibody Mediated Targeted Drug Delivery System To Improve Immunotherapy In Pancreatic Cancer, Poornima Devi Shaji, Meena Jaggi, Murali M. Yallapu, Subhash C. Chauhan, Sheema Khan

Research Symposium

About 95% of tumor arises from epithelial cell lining ducts known to be pancreatic ductal adenocarcinomas, with less than 5-7% survival rate. Unfortunately, little progress has been seen in the outcomes of patients with PDAC as tumor develops high desmoplasia and chemo-resistance to chemotherapeutic drugs, such as gemcitabine (Gem). Immunotherapy has shown promising results in cancers, except pancreatic cancer due to their characteristic fibrotic tumor microenvironment. The therapies are unable to penetrate to the fibrotic tumors leading to insufficient availability of the therapeutic drugs at the tumor site. A recently identified mucin, MUC13 is aberrantly expressed in pancreatic tumors but …

Tata-Box Binding Protein Interacts With Antp, Scr, Ubx And Abdb Through Their N-Terminal Domains, Rubén Montalvo Méndez, Gustavo Jiménez Mejía, Diana Reséndez Pérez

Research Symposium

Background: Hox proteins are transcriptional factors (TFs) that define segment identity during embryonic development regulating specific target genes. These TFs interact with cofactors for DNA specificity and other TFs to regulate gene expression, which include basal transcriptional machinery members like BIP2, Med19, TFIIEβ, M1BP and TBP. Since TBP glutamine homopeptide (PolyQ) act as an interaction domain involved transcriptional regulation, we analyzed if TBP interact with Antp, Scr, Ubx and AbdB through its PolyQ region.

Methods: We used Bimolecular Fluorescent Complementation (BiFC) to determine TBP interaction with Antp, Scr, Ubx and AbdB as well as the implication of their homeodomain (HD) …

Trimeric Interaction Of Antp-Ubx With Tbp And Homeoprotein Exd In The Genetic Control Of Development In D. Melanogaster, Alely Cecilia Villarreal-Puente, Claudia Dalila Altamirano-Torres, Diana Resendez-Perez 2023 Universidad Autonoma de Nuevo Leon

Trimeric Interaction Of Antp-Ubx With Tbp And Homeoprotein Exd In The Genetic Control Of Development In D. Melanogaster, Alely Cecilia Villarreal-Puente, Claudia Dalila Altamirano-Torres, Diana Resendez-Perez

Research Symposium

Homeoproteins specify body segments along the anteroposterior axis during embryo development; they bind DNA through the homeodomain (HD). Homeoproteins bind to similar and repetitive target sequences on DNA, raising the question of how they achieve functional specificity. Homeoproteins form complexes with proteins through the HDs or other regions. Antennapedia (Antp) and Ultrabithorax (Ubx) have an important role in conferring thorax identity; also they are involved in a repression transcriptional mechanism: Ubx binds to Antp promoter repressing its expression. We analyzed if Ubx and Antp perform protein-protein interaction as a regulation mechanism and if the complex Antp-Ubx are involved in trimeric …

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 …

Cell-Based Screening Of Antistress Activity Of Some Phytochemicals: Identification, Validation, And Relevance To Old-Age Related Pathologies, Huayue Zhang, Sunil Kaul, Renu Wadhwa

Research Symposium

Background: A variety of environmental stresses have been shown to contribute to poor quality of life, tissue dysfunctions and ailments including metabolic disorders, cognitive impairment, and accelerated aging. Oxidative stress (an imbalance between the production and processing of highly reactive oxygen species) is largely associated with these phenotypes. Whereas drug development and disease therapeutics have advanced remarkably in last three decades, there are still limited options for stress management. Since the later can effectively decrease the disease burden, we aimed to screen phytochemicals with anti-oxidative stress activity using cell-based assays.

Methods: Brain-derived cells were subjected to chemical models of oxidative …

Pro-Apoptosis Activity Of Pogostemon Cablin Benth. Against Nasopharyngeal Carcinoma Through The Bcl-2 Inhibition Signaling Pathway: A Computational Investigation, Aigia Syahraini, Essy Harnelly, Feri Eko Hermanto

Makara Journal of Science

Resistance to chemotherapy and radiotherapy frequently emerges in the later stage of nasopharyngeal carcinoma (NPC) tumorigenesis. The decreased response of NPC to radiotherapy and chemotherapy occurs owing to the inhibition of cancer cell apoptosis by the B-cell lymphoma-2 (BCL-2) protein. Thus, inhibiting BCL-2 protein may become a powerful approach to eliminate NPC through apoptosis regulation. Meanwhile, Pogostemon cablin is reported to exhibit anticancer properties, but there are limited studies on its use for NPC treatment. The objective of this study is to investigate the potential bioactive compounds in P. cablin as anti-apoptosis BCL-2 protein inhibitors using in-silico approach. Natural compounds …

Examining Pi3k-Signaling-Dependent Regulation Of Lens Organelle Free Zone Formation Via Immunolocalization And Immunoblotting In Chick Embryos, Rifah Gheyas, A. Sue Menko

Computational Medicine Center Faculty Papers

The elimination of lens organelles during development, required for mature lens function, is an autophagy-dependent mechanism induced through suppression of PI3K signaling. Here, we present a protocol for investigating the signaling pathways responsible for induction of the formation of this lens organelle free zone. We describe steps for preparation of lens organ culture and use of signaling pathway inhibitors. We then detail procedures for analyzing their impact using both confocal microscopy imaging of immunolabeled lens cryosections and immunoblot approaches. For complete details on the use and execution of this protocol, please refer to Gheyas et al. (2022).

The Use Of Prognostic Markers To Predict Disease Progression And Clinical Outcome In Monoclonal Gammopathy Of Undetermined Significance, Smouldering Multiple Myeloma And Multiple Myeloma., Róisín C. Mcmonagle

International Undergraduate Journal of Health Sciences

Multiple Myeloma (MM) is an incurable plasma cell malignancy with a complex and incompletely understood molecular pathogenesis. Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smouldering Multiple Myeloma (SMM) precede MM, with variable risks and rates of disease progression. The continuing high relapse and death rate in MM cases has prompted research into more accurate prognostic markers to predict progression from MGUS and SMM to MM, as well as identify MM cases with aggressive disease, in order to begin early, targeted and effective therapeutic intervention. Many studies have focused on utilising current markers more effectively, including M-protein, serum-free light chain ratio, …

Faculty Publications

In the literature there are numerous reports of developmental deformities in arthropods collected in their natural habitat. Since such teratogenically affected individuals are found purely by chance, the causes of their defects are unknown. Numerous potential physical, mechanical, chemical, and biological teratogens have been considered and tested in the laboratory. Thermal shocks, frequently used in teratological research on the spider Eratigena atrica, have led to deformities on both the prosoma and the opisthosoma. In the 2020/2021 breeding season, by applying alternating temperatures (14 °C and 32 °C, changed every 12 h) for the first 10 days of embryonic development, …
