Impact of Cystic Fibrosis Transmembrane Conductance Regulator Modulators on Maternal Outcomes During and After Pregnancy.

Background: Cystic fibrosis (CF) transmembrane conductance regulator (CFTR) modulators are available to the majority of people with CF in the United States; little is known about pregnancy outcomes with modulator use. The aim of this retrospective study was to determine the impact of CFTR modulators on maternal outcomes.

Research Question: Does pregnancy differentially affect outcomes in female individuals with CF with and without CFTR modulator exposure?

Study Design And Methods: Data on pregnancies from 2010 to 2021 were collected from 11 US adult CF centers.

Diagnostic and Prognostic Markers for Pancreatitis and Pancreatic Ductal Adenocarcinoma.

Diagnostic markers are desperately needed for the early detection of pancreatic ductal adenocarcinoma (PDA). We describe sets of markers expressed in temporal order in mouse models during pancreatitis, PDA initiation and progression. Cell type specificity and the differential expression of PDA markers were identified by screening single cell (sc) RNAseq from tumor samples of a mouse model for PDA (KIC) at early and late stages of PDA progression compared to that of a normal pancreas.

Gq-Gi-PLCβ in cells: More than the sum of its reconstituted parts.

The recent paper by Pfeil et al., "Heterotrimeric G Protein Subunit Gαq Is a Master Switch for Gβγ-Mediated Calcium Mobilization by Gi-Coupled GPCRs", opens another path from biochemical in vitro reconstitution to understanding the complex regulation of calcium signaling inside the cell.
