Neoadjuvant chemotherapy and radiotherapy outcomes in borderline-resectable and locally-advanced pancreatic cancer patients.

Background: There is no agreed upon standard of care for borderline-resectable pancreatic cancer (BRPC) or locally-advanced pancreatic cancer (LAPC) patients regarding the benefit of chemotherapy or radiation alone or in combination.

Patients And Methods: We completed a retrospective cohort analysis of BRPC and LAPC patients at a cancer center with expertise in multi-disciplinary pancreatic ductal adenocarcinoma (PDAC) treatment over a 5-year period from 03/01/2014 to 03/01/2019 (cut-off date). The total evaluable newly diagnosed, treatment naïve, BRPC, and LAPC patients with adequate organ function and ability to obtain treatment after multidisciplinary review was 52 patients.

OPTN is a host intrinsic restriction factor against neuroinvasive HSV-1 infection.

Fast-replicating neurotropic herpesviruses exemplified by herpes simplex virus-1 (HSV-1) naturally infect the central nervous system (CNS). However, most individuals intrinsically suppress the virus during a primary infection and preclude it from significantly damaging the CNS. Optineurin (OPTN) is a conserved autophagy receptor with little understanding of its role in neurotropic viral infections.

Dimerization and ubiquitin mediated recruitment of A20, a complex deubiquitinating enzyme.

A20 is an anti-inflammatory protein linked to multiple human autoimmune diseases and lymphomas. A20 possesses a deubiquitinating motif and a zinc finger, ZF4, that binds ubiquitin and supports its E3 ubiquitin ligase activity. To understand how these activities mediate A20's physiological functions, we generated two lines of gene-targeted mice, abrogating either A20's deubiquitinating activity (Tnfaip3(OTU) mice) or A20's ZF4 (Tnfaip3(ZF4) mice).
