A red/blue optoswitch for temporal control of chloroplast transcription and biogenesis in Arabidopsis

Nature Communications
Photosynthesis genes in plant chloroplasts are transcribed by the plastid-encoded RNA polymerase called PEP. Consequently, PEP-deficient mutants cannot generate a photosynthetic apparatus and develop non-viable albino seedlings. Inducible complementation

Mitochondria‐Targeted Nanotherapeutics: A Promising Strategy in Modulating Mitochondrial Function, Transfer, and Transplantation

Advanced Science, EarlyView.
This review summarizes the pathogenic role of mitochondria in diseases and highlights mitochondrial transfer and transplantation as emerging therapeutic strategies. It systematically discusses how nanomaterials are engineered to facilitate these processes, and critically examines the current challenges and future perspectives for their clinical ...

Ciliary Membrane Lipid Homeostasis in Health and Disease

Advanced Science, EarlyView.
This review systematically delineates the distinct lipid landscapes of ciliary membranes, including the spatial organization of phosphoinositides, cholesterol, and sphingolipids. It elucidates how these lipids orchestrate ciliogenesis, signal transduction, and membrane dynamics in cilia beating, and highlights how their dysregulation drives ...

Characterisation of Pex30-family proteins in organelle biogenesis and membrane contact sites

Membrane lipids and proteins produced in the endoplasmic reticulum (ER) are used for the de novo assembly of organelles, such as lipid droplets (LDs) and peroxisomes. After assembly, the growth and function of these organelles are supported by ER-derived

Cloning and characterisation of SSV genes from Saccharomyces Cerevisiae [PDF]

, 1995
In order to investigate the pleiotropic effects exhibited by mutations of S. cerevisiae defective in genes involved in vacuole biogenesis, a number of mutants were chosen for further study.

Transfer RNA‐Derived Small RNA‐5’tiRNAGln Drives HNRNPC Phase Separation to Promote Breast Cancer Bone Metastasis by Regulating IGF1R

Advanced Science, EarlyView.
This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.

Mechanically Regulated Secretion: How Physical Forces Instruct the Secretory Pathway and Remodel the Secretome [PDF]

Advanced science
Mechanical cues, including ECM stiffness, stretch, compression, shear stress, and traction forces, remodel trafficking across the secretory pathway, from the ER and Golgi to endolysosomal compartments and the plasma membrane. The resulting secretome reshapes ECM composition and tissue mechanics, establishing feedback loops that support homeostasis or ...

T‐Cell Remodeling in Renal Fibrosis: From Acute Injury to Chronic Kidney Disease

Advanced Science, EarlyView.
This Review presents renal fibrosis as a sequence of overlapping T‐cell programs, from chemokine‐guided recruitment and metabolic activation to maladaptive polarization, tertiary lymphoid structure formation, tissue residency, exhaustion, and senescence.

Organelles and Extracellular Vesicles in Bone Aging

Bone aging is characterized by a decline in bone mass and structural integrity, increasing fracture and osteoporosis risks in the elderly. This process involves cellular and molecular changes, including impaired osteoblast and osteoclast activity ...

Magnetoreceptor Promotes Hepatocellular Carcinoma Development and Blunts Sorafenib‐Induced Ferroptosis by Regulating Iron Homeostasis

Advanced Science, EarlyView.
Magnetoreceptor (MagR) regulates iron homeostasis and mitochondrial function in hepatocellular carcinoma (HCC) cells. Specifically, MagR deficiency suppresses tumor cell proliferation, migration, and invasion and enhances sorafenib‐induced ferroptosis through iron accumulation.
