Macropinocytosis coordinates non-specific uptake of macromolecules and fluid. Cancers employ macropinocytosis to obtain nutrients to support their metabolic homeostasis. In this issue of Developmental Cell, Lee et al. (2019) report that glutamine deprivation boosts macropinocytosis via EGFR signaling induction, providing a fine-tuned mechanism by which cancers adapt to nutrient supply.

The decline in intestinal stem cell (ISC) function is a hallmark of aging, contributing to compromised intestinal regeneration and increased incidence of age-associated diseases. Novel therapeutic agents that can rejuvenate aged ISCs are of paramount importance for extending healthspan. Here, we report on the discovery of Chrysosplenosides I and A (CAs 1 & 2), flavonol glycosides from the Xizang medicinal plant Maxim.

Background: Renal fibrosis is crucial in the progression of chronic kidney disease (CKD) to end-stage renal failure. Geniposide, an iridoid glycoside, has shown therapeutic potential in acute kidney injury, diabetic nephropathy, and atherosclerosis. The aim of this study was to investigate the role of geniposide in renal fibrosis and its underlying mechanisms.

Glioblastoma (GBM) classification involves a combination of histological and molecular signatures including IDH1/2 mutation, TERT promoter mutation, and EGFR amplification. Non-canonical mutations such as BRAF, found in 1-2% of GBMs, activate the MEK-ERK signaling pathway. This mutation can be targeted by small molecule inhibitors, offering therapeutic potential for GBM.

Cellular senescence is an irreversible cell cycle arrest caused by various stressors that damage cells. Over time, senescent cells accumulate and contribute to the progression of multiple age-related degenerative diseases. It is believed that these cells accumulate partly due to their ability to evade programmed cell death through the development and activation of survival and antiapoptotic resistance mechanisms; however, many aspects of how these survival mechanisms develop and activate are still unknown.
