Changes in cellular metabolism drive hematopoietic stem cell (HSC) behavior during homeostasis, although whether they control HSC behavior during stress conditions is unclear. In this issue of Cell Stem Cell, Karigane et al. (2016) identify a p38α-dependent pathway that alters purine metabolism in HSCs during stress hematopoiesis, promoting hematopoietic recovery.

Gastric cancer is an aggressive malignancy characterized by significant clinical heterogeneity arising from complex genetic and environmental interactions. This study employed single-cell RNA sequencing, using the 10 × Genomics platform, to analyze 262,532 cells from gastric cancer samples, identifying 32 distinct clusters and 10 major cell types, including immune cells (e.g.

This research seeks to address the gap in past studies by examining the role of the Nrf2 (nuclear factor erythroid 2-related factor 2) and HO-1 (heme oxygenase-1) signaling pathways in hypoxia and the potential effects of alpha-pinene on these factors. Wistar rats were divided into 7 experimental groups (n = 7): 1) control, 2 and 3) groups receiving alpha-pinene 5 and 10 mg/kg (i.p.
