PDZK1‐ULK1 Axis Triggers Lipophagy to Inhibit Tumor Progression and Sunitinib Resistance in Clear Cell Renal Cell Carcinoma

Advanced Science, EarlyView.
This study reveals that PDZK1 loss impairs ULK1‐mediated lipophagy, driving lipid droplet accumulation and sunitinib resistance in clear cell renal cell carcinoma. PDZK1 inhibits LEF1 nuclear translocation, enhancing ULK1 transcription. Pharmacological ULK1 activation resensitizes resistant tumors to sunitinib.

Super‐Enhancer‐Driven SOX4/SMAD3 Mediate Membrane Remodeling by Regulating Phospholipid Metabolism to Accelerate Leukemia Progression

Advanced Science, EarlyView.
Chronic myeloid leukemia blast phase (CML‐BP) poses a severe therapeutic challenge. This study reveals that the super‐enhancer‐driven transcription factors SOX4 and SMAD3 form a cooperative axis critical for disease progression. They co‐activate the oncogenic kinase AXL and promote phospholipid remodeling via LPCAT1 to facilitate its signaling ...

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, EarlyView.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

Advanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support

ITGB1 Regulates Triple‐Negative Breast Cancer Development by Modulating the Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumorigenesis and metastasis are frequently attributed to the intricate interplay between cancer cells and the tumor microenvironment (TME). Comprehending the mechanisms and key regulators of cancer‐immune crosstalk in the TME is imperative for developing efficacious immunotherapy.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, EarlyView.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...
