AMPK regulates phagophore-to-autophagosome maturation

Journal of Cell Biology
Autophagy is an important metabolic pathway that can non-selectively recycle cellular material or lead to targeted degradation of protein aggregates or damaged organelles. Autophagosome formation starts with autophagy factors accumulating on lipid vesicles containing ATG9.

A requirement for ER-derived COPII vesicles in phagophore initiation [PDF]

Autophagy, 2014
A major unanswered question in the field of autophagy is how the double-membrane phagophore is formed. As this membrane expands, it engulfs proteins and organelles that are destined for degradation and then seals to form an autophagosome. A growing consensus in the field is that a subdomain of the ER initiates formation of the phagophore.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Hepatic cytochromes P450: structural degrons and barcodes, posttranslational modifications and cellular adapters in the ERAD-endgame. [PDF]

, 2016
The endoplasmic reticulum (ER)-anchored hepatic cytochromes P450 (P450s) are enzymes that metabolize endo- and xenobiotics i.e. drugs, carcinogens, toxins, natural and chemical products.

Determining Atg protein stoichiometry at the phagophore assembly site by fluorescence microscopy [PDF]

Autophagy, 2010
In eukaryotic cells, autophagy is a lysosomal/ vacuolar degradative pathway necessary for the turnover of different macromolecules. Autophagy is under precise regulation, not only qualitatively but also quantitatively, and excess or reduced levels of autophagy may lead to various human diseases.

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.

Membrane Contact Sites and Organelles Interaction in Plant Autophagy

Frontiers in Plant Science, 2020
Autophagy is an intracellular trafficking and degradation system for recycling of damaged organelles, mis-folded proteins and cytoplasmic constituents. Autophagy can be divided into non-selective autophagy and selective autophagy according to the cargo ...

Basal ryanodine receptor activity suppresses autophagic flux [PDF]

, 2017
The inositol 1,4,5-trisphosphate receptors (IP3Rs) and intracellular Ca2+ signaling are critically involved in regulating different steps of autophagy, a lysosomal degradation pathway.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Genetic aberrations in macroautophagy genes leading to diseases [PDF]

, 2018
The catabolic process of macroautophagy, through the rapid degradation of unwanted cellular components, is involved in a multitude of cellular and organismal functions that are essential to maintain homeostasis.
