Macrophage-Specific MAFB Deficiency Leads to Poor Prognosis in Acute Kidney Injury

Acute kidney injury (AKI) is associated with a poor prognosis, and no effective treatment has been established to date. Understanding the mechanisms that prevent the progression of AKI is crucial. In AKI, immune cells known as macrophages produce lipid mediators (LMs), which are lipids with significant physiological activity and play a pivotal role in promoting and suppressing inflammation. Thus, elucidating their function is of paramount importance.

Circadian Rhythm Disrupts Gut Barrier in Cancer

Research from the University of California, Irvine has revealed how disruption of the circadian clock, the body's internal, 24-hour biological pacemaker, may accelerate the progression of colorectal cancer by affecting the gut microbiome and intestinal barrier function. This discovery offers new avenues for prevention and treatment strategies.

A New Method to Correct Misplaced Proteins in Cells

Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally stands watch over DNA replicating in the nucleus is sent far from the DNA it is meant to monitor, allowing cancers to grow.
