A bitter anti-inflammatory drug binds at two distinct sites of a human bitter taste GPCR.

Bitter taste receptors (TAS2Rs), a subfamily of G-protein coupled receptors (GPCRs) expressed orally and extraorally, elicit signaling in response to a large set of tastants. Among 25 functional TAS2Rs encoded in the human genome, TAS2R14 is the most promiscuous, and responds to hundreds of chemically diverse ligands. Here we present the cryo-electron microscopy (cryo-EM) structure of the human TAS2R14 in complex with its signaling partner gustducin, and bound to flufenamic acid (FFA), a clinically approved nonsteroidal anti-inflammatory drug.

Pancreatic ductal adenocarcinoma, β-blockers and antihistamines: A clinical trial is needed.

Survival in pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC) at just 5 months is the worst of all cancers. It is predicted to become the second highest cause of cancer deaths worldwide this decade and unlike most cancers, there has been little progress in improving survival in PDAC. Numerous studies including molecular and mechanistic studies, cancer biology studies and retrospective human epidemiological studies suggest that two well-known, approved drug classes - β-blockers and H1-antihistamines - may be beneficial and thus may potentially prolong life in patients with PDAC.

Factors Influencing Outcomes and Survival in Anal Cancer.

Background: We aim to ascertain prognostic factors in the current management of anal cancer within this study.

Methods: We reviewed the management and outcomes of anal cancer cases over a seven-year period, inclusive (2016-2023). The primary objectives were to assess the demographic characteristics, clinical presentation, and outcomes of all anal cancer patients within our institution.

Complement is increased in treatment resistant rectal cancer and modulates radioresistance.

Resistance to neoadjuvant chemoradiation therapy (neo-CRT) is a significant clinical problem in the treatment of locally advanced rectal cancer. Identification of novel therapeutic targets and biomarkers predicting therapeutic response is required to improve patient outcomes. Increasing evidence supports a role for the complement system in resistance to anti-cancer therapy.
