Epigenetic Reactivation of TNFRSF19 Suppresses Mitophagy and Sensitizes Triple‐Negative Breast Cancer to Doxorubicin

Advanced Science, EarlyView.
TNFRSF19 is an epigenetically silenced regulator of mitophagy in triple‐negative breast cancer. TNFRSF19 deficiency activates the TGFBR1–SMAD3–PINK1 axis to promote mitophagy and confer doxorubicin resistance, whereas decitabine‐mediated restoration of TNFRSF19 suppresses mitophagy and enhances doxorubicin sensitivity, revealing a targetable epigenetic–

Autolysosome biogenesis and developmental senescence are regulated by both Spns1 and v-ATPase

, 2016
Spns1 (Spinster homolog 1 [Drosophila]) in vertebrates, as well as Spin (Spinster) in Drosophila, is a hypothetical lysosomal H+-carbohydrate transporter, which functions at a late stage of macroautophagy (hereafter autophagy).

Revisiting Rab7 Functions in Mammalian Autophagy: Rab7 Knockout Studies

Cells, 2018
Rab7 (or Ypt7 in yeast) is one of the well-characterized members of the Rab family small GTPases, which serve as master regulators of membrane trafficking in eukaryotes.

CCL20/CCR6 axis mediates macrophages to promote proliferation and migration of ESCs by blocking autophagic flux in endometriosis

Stem Cell Research & Therapy, 2022
Background Endometriosis (EMs) is a common benign gynecological disease that affects approximately 10% of females of reproductive age. Endometriosis ectopic lesions could recruit macrophages, which in turn facilitates endometriosis progression.

Mutant KRAS‐m6A Epitranscriptome Axis Promotes Colorectal Cancer and is a Therapeutic Target

Advanced Science, EarlyView.
Mutant KRAS‐m6A axis promotes colorectal cancer (CRC) progression. Mutant KRAS stabilizes METTL3, leading to increased m6A‐modified BCL9L mRNA and translation of BCL9L protein. BCL9L in turn mediates TGF‐β secretion to induce differentiation of Treg and an immunosuppressive microenvironment.

Lyssavirus Nucleoprotein Induces GPAT4‐Mediated CYB5R1 Depalmitoylation to Suppress Ferroptosis and Promote Viral Replication

Advanced Science, EarlyView.
Lipid metabolism plays a vital role in viral infections. Here, we reveal that the lyssavirus N protein regulates GPAT4 to induce lipid droplet biogenesis, restricting CYB5R1 palmitoylation and reducing ferroptosis susceptibility to ultimately promote viral replication.

The non-structural proteins NS3 and NS5A of Hepatitis C Virus (HCV) are degraded by two host proteolysis systems

, 2023
Each lifecycle of the Hepatitis C virus (HCV) produces structural and non-structural (NS) proteins in equimolar. Structural proteins were either assembled or degraded by host proteolysis systems, while NS proteins remain inside the host cells and don’t ...

Zika virus impairs autophagic flux in trabecular meshwork, and inhibition of autophagy restricts ocular viral transmission and associated pathology

Microbiology Spectrum
Zika virus (ZIKV) is the lone member of Flavivirus family known to cause congenital glaucoma following in utero exposure. The molecular mechanisms of ZIKV-induced glaucoma remain elusive, with no known therapeutic modalities.

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

NLRX1 Negatively Regulates Group A Streptococcus Invasion and Autophagy Induction by Interacting With the Beclin 1–UVRAG Complex

Frontiers in Cellular and Infection Microbiology, 2018
Group A Streptococcus (GAS) can invade epithelial cells; however, these bacteria are targeted and eventually destroyed by autophagy. Members of the Nod-like receptor (NLR) family are thought to be critical for the autophagic response to invasive bacteria.
