HPV-DNA testing from self-sampled menstrual blood using M-strip: A proof-of-concept study on feasibility & acceptance of a novel biosampling method.

Background & objectives Screening for cervical cancer by self-sampling appears more acceptable to women and has the potential to boost screening uptake, which is dismal at present in India. Studies have shown that menstrual blood (MB) provides equivalent results to cervical smear for Human Papillomavirus (HPV)-Deoxyribonucleic acid (DNA) testing, but sample collection needs standardization. This study explored the feasibility and acceptance of self-sampling using 'M-strip' for high-risk HPV DNA (hr-HPV DNA) testing from MB.

CREB Drives Acinar to Ductal Cells Reprogramming and Promotes Pancreatic Cancer Progression in Preclinical Models of Alcoholic Pancreatitis.

Background & Aims: Chronic alcoholism often leads to pancreatitis, which exacerbates pancreatic damage through acinar cell injury and fibrotic inflammation activating AKT/mTOR/cyclic adenosine monophosphate response element binding protein 1 (CREB) signaling axis. However, the molecular interplay between oncogenic Kras(Kras∗) and CREB in promoting pancreatic cancer progression under chronic inflammation remains poorly understood.

Methods: Experimental alcoholic chronic pancreatitis (ACP) induction was established in multiple mouse models, with euthanasia during the recovery stage to evaluate tumor latency.

Cell-specific nanoengineering strategy to disrupt tolerogenic signaling from myeloid-derived suppressor cells and invigorate antitumor immunity in pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by intratumoral abundance of neutrophilic/polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) which exert anti-T-cell functions through multiple mechanisms, especially JAK2/STAT3-regulated arginase activity. To overcome limitations of systemic inhibition of PMN-MDSCs in cancer-bearing patients such as neutropenia and compensatory myelopoietic adaptations, we developed a nanoengineering strategy to disrupt cell-specific signaling exclusively in PMN-MDSCs without compromising viability or provoking neutropenia. Single-cell RNA sequencing in human/murine PDAC, and flow cytometry in peripheral blood cells from treatment-naïve PDAC patients, nominated surface receptor CXCR2 as a PMN-MDSC-exclusive target.

Multifunctional hydrogels with spatially controlled light activation with photocaged oligonucleotides.

Recreating tissue environments with precise control over mechanical, biochemical, and cellular organization is essential for next-generation tissue models for drug discovery, development studies, and the replication of disease environments.

Here, we report the development of printing approaches that leverage polyethylene glycol diacrylate (PEGDA) hydrogels containing photocaged oligonucleotides to spatially program material characteristics with non-destructive, non-ultraviolet light.

CREB drives acinar cells to ductal reprogramming and promotes pancreatic cancer progression in preclinical models of alcoholic pancreatitis.
