Peripheral positioning of lysosomes supports melanoma aggressiveness

Nature Communications
Emerging evidence suggests that the function and position of organelles are pivotal for tumor cell dissemination. Among them, lysosomes stand out as they integrate metabolic sensing with gene regulation and secretion of proteases. Yet, how their function

Tracking Lysosome Migration within Chinese Hamster Ovary (CHO) Cells Following Exposure to Nanosecond Pulsed Electric Fields

Bioengineering, 2018
Above a threshold electric field strength, 600 ns-duration pulsed electric field (nsPEF) exposure substantially porates and permeabilizes cellular plasma membranes in aqueous solution to many small ions.

How Nutrients Orchestrate Lysosome Positioning

, 2018
As part of a starvation response, lysosomes cluster perinuclearly. This facilitates fusion between lysosomes and autophagosomes and ensures activation of catabolic processes.

Rheb localized on the Golgi membrane activates lysosome-localized mTORC1 at the Golgi-lysosome contact site

, 2017
In response to amino acid supply, mTORC1, a master regulator of cell growth, is recruited to the lysosome and activated by a small GTPase, Rheb. However, the intracellular localization of Rheb is controversial. In this study, we showed that a significant

Overcoming Photodynamic Therapy Resistance: GSH‐Responsive AIE Photosensitizer‐Hydroxycamptothecin Nanoliposomes for Extrahepatic Cholangiocarcinoma

Advanced Healthcare Materials, EarlyView.
A GSH‐responsive AIE nanoplatform (TSH NPs) with RGD‐mediated tumor targeting co‐delivers a photosensitizer (TPA) and HCPT for extrahepatic cholangiocarcinoma. The system synergistically enhances PDT and chemotherapy by suppressing HIF‐1α/VEGF‐driven hypoxic adaptation, effectively overcoming PDT resistance.

Action myoclonus-renal failure syndrome: diagnostic applications of activity-based probes and lipid analysis

Journal of Lipid Research, 2014
Lysosomal integral membrane protein-2 (LIMP2) mediates trafficking of glucocerebrosidase (GBA) to lysosomes. Deficiency of LIMP2 causes action myoclonus-renal failure syndrome (AMRF).
