Time matters: the dynamics of plasma membrane repair

Trends in Cell Biology
The plasma membrane (PM) of eukaryotic cells is constantly exposed to many challenges that can cause wounds that necessitate rapid and efficient repair mechanisms to ensure cell survival. PM wound repair not only encompasses the immediate resealing of the membrane barrier, which involves exocytosis of internal vesicles to deliver membrane, but also ...

A role for eIF5A in translational control of stress‐inducible proteins in multiple myeloma cell lines

Molecular Oncology, EarlyView.
Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.

LAMP-2 absence interferes with plasma membrane repair and decreases T. cruzi host cell invasion.

PLoS Neglected Tropical Diseases, 2017
Trypanosoma cruzi enters host cells by subverting the mechanism of cell membrane repair. In this process, the parasite induces small injuries in the host cell membrane leading to calcium entry and lysosomal exocytosis, which are followed by compensatory ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Membrane Tension Regulation is Required for Wound Repair

Advanced Science
Disruptions of the eukaryotic plasma membrane due to chemical and mechanical challenges are frequent and detrimental and thus need to be repaired to maintain proper cell function and avoid cell death.

Characterization of FER1L5, a novel dysferlin myoferlin related protein [PDF]

, 2009
The ferlins are mammalian homologues of the C-elegans sperm vesicle fusion protein FER-1 characterised by multiple C2 domains and a C-terminal anchor.

Co-ordinated mechanisms of plasma membrane repair responses adopted by mammalian cells against pore forming toxins [PDF]

, 2022
Pore forming toxins (PFTs) play an integral part of the virulence arsenal of both bacterial and fungal pathogens such as Streptococcus pyogenes, Clostridiun perfringens, Aeromonas hydrophila or Candida albicans.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Characterization of therapeutic antibodies targeting lymphatic and vascular resistance factor for the treatment of hypervascularized and highly metastatic cancers

Molecular Oncology, EarlyView.
LVRF (lymphatic and vascular resistance factor) is a VEGFA splice variant upregulated in response to anti‐angiogenic therapy that fosters tumor adaptation through enhanced vascularization, lymphangiogenesis, and metastatic dissemination. Targeting LVRF with fully human neutralizing antibodies disrupts these processes and limits resistant tumor growth ...
