Autophagy Plays a Suppressive Role in Bladder Tumor Formation in an Orthotopic Mouse Model and Bladder Cancer Patient Specimens

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Autophagy plays either a suppressing or promoting role during tumor development. Clarifying the role of autophagy in bladder tumorigenesis both in vitro and in vivo is crucial for developing novel therapeutic strategies through manipulating autophagy activity.

Bim Inhibits Autophagy by Recruiting Beclin 1 to Microtubules [PDF]

Molecular Cell, 2012
Bim is a proapoptotic BH3-only Bcl-2 family member. In response to death stimuli, Bim dissociates from the dynein light chain 1 (DYNLL1/LC8), where it is inactive, and can then initiate Bax/Bak-mediated mitochondria-dependent apoptosis. We found that Bim depletion increases autophagosome synthesis in cells and in vivo, and this effect is inhibited by ...

Aberrant Autophagic Response in The Muscle of A Knock-in Mouse Model of Spinal and Bulbar Muscular Atrophy [PDF]

, 2015
Spinal and bulbar muscular atrophy (SBMA) is characterized by loss of motoneurons and sensory neurons, accompanied by atrophy of muscle cells. SBMA is due to an androgen receptor containing a polyglutamine tract (ARpolyQ) that misfolds and aggregates ...

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

New Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Regulation of autophagy by Beclin 1 in the heart [PDF]

Journal of Molecular and Cellular Cardiology, 2016
Dysregulation of autophagy in cardiomyocytes is implicated in various heart disease conditions. Beclin 1, a mammalian ortholog of yeast Atg6 and a core component of the autophagy machinery, plays a central role in the regulation of autophagy through activation of Vps34.

Inhibition of Autophagy Signaling via 3-methyladenine Rescued Nicotine-Mediated Cardiac Pathological Effects and Heart Dysfunctions. [PDF]

, 2020
Rationale: Cigarette smoking is a well-established risk factor for myocardial infarction and sudden cardiac death. The deleterious effects are mainly due to nicotine, but the mechanisms involved and theranostics remain unclear.

Evidence for the involvement of lipid rafts localized at the ER-mitochondria associated membranes in autophagosome formation [PDF]

, 2016
Mitochondria-associated membranes (MAMs) are subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. This membrane scrambling between ER and mitochondria appears to play a critical role in the earliest steps of autophagy.

Bridging Psychological Stress and Skin Cellular Aging: Flavonoids as a Dual‐Action Therapeutic Strategy

Phytotherapy Research, EarlyView.
ABSTRACT Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which ...

Prognostic significance of Beclin 1 in intrahepatic cholangiocellular carcinoma [PDF]

Autophagy, 2011
Autophagy enables cells to recycle long-lived proteins or damaged organelles. Beclin 1 plays important roles in autophagy, differentiation, apoptosis and the development and progression of cancer, but the expression of Beclin 1 and its possible role in primary intrahepatic cholangiocarcinoma (ICC) has not been reported yet.

Lipid Nanoparticles Delivering ClpP‐mRNA Suppress Pyroptosis and Senescence in Intervertebral Disc Degeneration via mTOR/BNIP3‐Activated Mitophagy

Rare Metals, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and
