Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse
Experimental Physiology, EarlyView.Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Rab7 Regulates Maturation of Melanosomal Matrix Protein gp100/Pmel17/Silv [PDF]
Journal of Investigative Dermatology, 2008 Melanosome biogenesis consists of multistep processes that involve synthesis of melanosomal protein, which is followed by vesicle transport/fusion and post-translational modifications such as glycosylation, proteolysis, and oligomerization. Because of its complexity, the details of the molecular mechanism of melanosome biogenesis are not yet fully ...

RAB family gene expression in breast cancer cells under influence of paclitaxel [PDF]
, 2011 The aim of this study was to investigate the role of paclitaxel on RAB family of genes in primary breast cancer cell lines. The cancer breast cells obtained from 40 women during mastectomy were used to address this issue. The group included patients with

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Mitochondria–lysosome contacts regulate mitochondrial fission via RAB7 GTP hydrolysis [PDF]
Nature, 2018 Both mitochondria and lysosomes are essential for maintaining cellular homeostasis, and dysfunction of both organelles has been observed in multiple diseases. Mitochondria are highly dynamic and undergo fission and fusion to maintain a functional mitochondrial network, which drives cellular metabolism.

The Role of BCA2 in the Endocytic Trafficking of EGFR and Significance as a Prognostic Biomarker in Cancer [PDF]
, 2016 Breast Cancer Associated gene 2 (BCA2) is an E3 ubiquitin ligase that is over-expressed in >50% of primary breast cancers, and has been shown to increase in vitro cell proliferation and invasion.

Acta Ophthalmologica, Volume 104, Issue 2, Page 239-251, March 2026.Abstract Purpose To examine the presence of secretory autophagy and epithelial–mesenchymal transition (EMT) in the macular retinal pigment epithelium (RPE) of human cadaver eyes with different forms of age‐related macular degeneration (AMD). Methods Human cadaver macula samples representing dry and wet AMD, as well as age‐matched controls, were ...

Role of the Small GTPase RAB7 in the Late Endocytic Pathway [PDF]
Journal of Biological Chemistry, 1997 Rab7 is a small GTPase localized to the late endosomal compartment. Its function was investigated by overexpressing dominant negative or constitutively active mutants in BHK-21 cells. The effects of such overexpression on the internalization and/or degradation of different endocytic markers and on the morphology of the late endosomal compartment were ...
