Targeting Mycobacterial Efflux System For Combating Anti-Microbial Resistance, Arathi Radhakrishnan, Raj Kishor Kapardar, Rajpal Srivastav

Research Symposium

Background: The drug resistance in the microbes is a serious concern in medicine. Along with intrinsic factors, extrinsic factors like unprescribed usage of drugs are the contributing factors. The drug tolerance has led to the emergence of superbugs. Mycobacterial species utilize an array of multidrug efflux mechanisms linked to intrinsic and acquired antibiotic resistance. Understanding molecular mechanisms regulating efflux could reveal new therapeutic targets and strategies. Our study is aimed to target regulators of efflux Mycobacterial transporter.

Methods: Using the reference mycobacterial strain, antibiotic sensitivity was first profiled by minimal inhibitory concentration assays across a panel of antimicrobials, followed by …

Piperlongumine Nanoformulation Attenuates Pancreatic Tumor Desmoplasia And Alter Tumor Immune Responses, Vivek Kumar Kashyap, Neeraj Chauhan, Mohammed Sikander, Eswara N. H. K. Ghali, Bilal Hafeez, Murali M. Yallapu, Meena Jaggi, Subhash C. Chauhan

Research Symposium

Pancreatic cancer (PanCa) is characterized by lack of early diagnosis, poor response to available therapeutic modalities and chemoresistance. Gemcitabine (GEM) is currently considered the most effective therapy for PanCa; however, it shows only a marginal survival benefit of 6 months. This poor drug response has been attributed to desmoplasia, causes suboptimal drug delivery, alters tumor microenvironment (TME), which includes tumor surrounding blood vessels, fibroblasts, immune cells, extracellular matrix, and other signaling molecules and induces chemo-resistance in tumors. To overcome these existing issues associated with chemotherapy, identification and development of novel therapeutic modalities are a pressing need. Piperlongumine (PL) is a …
