Physiology
Peroxisomes contribute to intracellular calcium dynamics in cardiomyocytes and non-excitable cellsUsing genetically encoded Förster resonance energy transfer calcium sensors for the peroxisome, this study dissects the previously contentious peroxisome involvement in calcium handling in HeLa cells and in cardiomyocytes derived from human induced pluripotent stem cells.
Small intestinal flora graft alters fecal flora, stool, cytokines and mood status in healthy miceTransplantation of microbiota from small intestine, not large intestine, of healthy mice exerts obvious effects on healthy recipients, bringing a new perspective on gut flora transplantation.
Role of opioid signaling in kidney damage during the development of salt-induced hypertensionStimulation of kappa opioid receptors modulates calcium influx via TRPC6 channels in podocytes, which ultimately compromises the integrity of the glomerular filtration barrier and promotes a marked worsening of blood pressure control and renal damage.
Differential regulation of hepatic physiology and injury by the TAM receptors Axl and MerThe TAM receptor tyrosine kinases Mer and Axl play critical roles in liver homeostasis and in the response to both acute and chronic liver injury.
Mylk3 null C57BL/6N mice develop cardiomyopathy, whereas Nnt null C57BL/6J mice do notGenetic differences between C57BL/6 substrains lead to different cardiovascular traits; a null mutation in Mylk3 likely causes cardiomyopathy in C57BL/6N mice, whereas C57BL/6J Nnt-null mice do not develop cardiomyopathy.
The health status alters the pituitary function and reproduction of mice in a Cxcr2-dependent mannerThis study explores the effects of microbiota on reproductive function of Cxcr2 knockout animals. Cxcr2 is involved in the control of pituitary action and the subsequent development of mammary gland, uterus and ovary.
Loss of autophagy impairs physiological steatosis by accumulation of NCoR1Autophagy regulates fatty acid and triglyceride synthesis at the transcriptional level by fine-tuning the levels of NCoR1, a negative regulator of nuclear receptors. Defective autophagy impairs physiological steatosis both under fasting conditions and after hepatectomy.
TMEM16A chloride channel does not drive mucus productionDespite being essential for airway hydration, TMEM16A is not required for mucus (MUC5AC) production. Cell proliferation is the main driver for TMEM16A up-regulation during inflammation.
Expression of a constitutively active human STING mutant in hematopoietic cells produces an Ifnar1-dependent vasculopathy in miceTransgenic expression of a mutant hSTING cDNA under the control of the Vav1 gene promoter leads to a vasculopathy similar to that of the interferonopathy, STING-associated vasculopathy of infancy.
m6A-mRNA methylation regulates cardiac gene expression and cellular growthThis study provides evidence that m6A methylation is dynamically regulated during human and murine cardiac disease and highlights an important role of the m6A methylase Mettl3 in regulating cardiac growth by gene expression control.
