  This fundamental study provides compelling evidence that TRPV4 plays a crucial role in mechanical sensing during cancer cell transition from non-invasive to invasive states, and offers novel insights into metastasis. By employing multiple experimental approaches, including pharmacological and genetic manipulation, as well as advanced imaging techniques, the authors demonstrate a strong correlation between TRPV4 dynamics, calcium homeostasis, and cell volume plasticity. The findings significantly enhance our understanding of mechanotransduction in cancer and present TRPV4 as a promising therapeutic target for inhibiting metastasis.

  This important study presents a transcriptomic analysis of enterochromaffin cells in the intestine. The evidence supporting the authors' claims is solid, although the functional analysis is focused on the Piezo2-expressing subset in the colon. The work will be of interest to biologists working on intestinal mucosal biology.

  This valuable study suggests that capsaicin nanoparticle administration in rats activates the transcription factor Nrf2 by directly binding to its repressor, KEAP1, leading to the induction of cytoprotective genes and preventing alcohol-induced gastric damage, offering a potential avenue for treating alcoholism-related gastric disorders. Although improvements were made following the first revision, the evidence supporting capsaicin as an Nrf2 activator remains incomplete, as some methodological aspects still require revision and the interpretation of key data needs further clarification.

  This valuable study offers insights into the role of Leiomodin-1 (LMOD1) in muscle stem cell biology, advancing our understanding of myogenic differentiation and indicating LMOD1 as a regulator of muscle regeneration, aging, and exercise adaptation. The integration of in vitro and in vivo approaches, complemented by proteomic and imaging methodologies, is solid. However, certain aspects require further attention to improve the clarity, impact, and overall significance of the work, particularly in substantiating the in vivo relevance. This work will provide a starting point that will be of value to medical biologists and biochemists working on LMOD and its variants in muscle biology.

  This fundamental research conducted a molecular comparison between smooth muscle cells and adjacent fibroblast cells within lung blood vessels affected by pulmonary arterial hypertension. The study identified distinct disease-related states in each cell type and provided deeper insights into their interactions and communication. While certain conclusions should be interpreted with caution due to inherent methodological limitations, the study's findings remain convincing and robust. This is supported by the use of advanced and complementary techniques, as well as the rare isolation of diseased lung blood vessel cells from the same donor, enabling direct comparison.
