Two distinct regulatory pathways govern Cct2-Atg8 binding in the process of solid aggrephagy.

CCT2 serves as an aggrephagy receptor that plays a crucial role in the clearance of solid aggregates, yet the underlying molecular mechanisms by which CCT2 regulates solid aggrephagy are not fully understood. Here we report that the binding of Cct2 to Atg8 is governed by two distinct regulatory mechanisms: Atg1-mediated Cct2 phosphorylation and the interaction between Cct2 and Atg11. Atg1 phosphorylates Cct2 at Ser412 and Ser470, and disruption of these phosphorylation sites impairs solid aggrephagy by hindering Cct2-Atg8 binding.

Ca as an essential signaling molecule controlling Snf1-mediated Atg1 activation.

Macroautophagy/autophagy is essential for maintaining glucose homeostasis, but the mechanisms by which cells sense glucose starvation and initiate autophagy are not yet fully understood. Recently, we reported that the assembly of a Ca-triggered Snf1-Bmh1/Bmh2-Atg11 complex initiates autophagy in response to glucose starvation. Our research reveals that during glucose starvation, the efflux of vacuolar Ca increases cytoplasmic Ca levels, which activates the protein kinase Rck2.

Ca2+-triggered Atg11-Bmh1/2-Snf1 complex assembly initiates autophagy upon glucose starvation.

Autophagy is essential for maintaining glucose homeostasis. However, the mechanism by which cells sense and respond to glucose starvation to induce autophagy remains incomplete. Here, we show that calcium serves as a fundamental triggering signal that connects environmental sensing to the formation of the autophagy initiation complex during glucose starvation.

A Quadruple Revolution: Deciphering Biological Complexity with Artificial Intelligence, Multiomics, Precision Medicine, and Planetary Health.

A quiet quadruple revolution has been in the making in systems science with convergence of (1) artificial intelligence, machine learning, and other digital technologies; (2) multiomics big data integration; (3) growing interest in the "variability science" of precision/personalized medicine that aims to account for patient-to-patient and between-population differences in disease susceptibilities and responses to health interventions such as drugs, nutrition, vaccines, and radiation; and (4) planetary health scholarship that both scales up and integrates biological, clinical, and ecological contexts of health and disease. Against this overarching background, this article presents and highlights some of the salient challenges and prospects of multiomics research, emphasizing the attendant pivotal role of systems medicine and systems biology. In addition, we emphasize the rapidly growing importance of planetary health research for systems medicine, particularly amid climate emergency, ecological degradation, and loss of planetary biodiversity.

Energy deprivation-induced autophagy and aggrephagy: insights from yeast and mammals.

Autophagy plays a crucial role in maintaining cellular homeostasis in response to various stimuli. Compared to research on nutrient deprivation-induced autophagy, the understanding of the molecular mechanisms and physiological/pathological significance of autophagy triggered by energy deprivation remains limited. A primary focus of our lab is to elucidate how cells sense energy deprivation and initiate autophagy.

The molecular mechanisms regulating the assembly of the autophagy initiation complex.

The autophagy initiation complex is brought about via a highly ordered and stepwise assembly process. Two crucial signaling molecules, mTORC1 and AMPK, orchestrate this assembly by phosphorylating/dephosphorylating autophagy-related proteins. Activation of Atg1 followed by recruitment of both Atg9 vesicles and the PI3K complex I to the PAS (phagophore assembly site) are particularly crucial steps in its formation.
