Filamin A C-terminal fragment modulates Orai1 expression by inhibition of protein degradation.
Am J Physiol Cell Physiol

Filamin A (FLNA) is an actin-binding protein that has been reported to interact with STIM1 modulating the activation of Orai1 channels. Cleaving of FLNA by calpain leads to a C-terminal fragment that is involved in a variety of functional and pathological events, including pro-oncogenic activity in different types of cancer. Here we show that full-length FLNA is downregulated in samples from colon cancer patients as well as in the adenocarcinoma cell line HT-29.

Background: Overdose of acetaminophen (APAP), a commonly used antipyretic analgesic, can lead to severe liver injury and failure. Current treatments are only effective in the early stages of APAP-induced acute liver injury (ALI). Therefore, a detailed examination of the mechanisms involved in liver repair following APAP-induced ALI could provide valuable insights for clinical interventions.

Department of Chemistry, College of Science, King Saud University, P.O. Box 2455, Riyadh 11451, Saudi Arabia.
Background: Cucurbitacin E glucoside (CEG), a prominent constituent of Cucurbitaceae plants, exhibits notable effects on cancer cell behavior, including inhibition of invasion and migration, achieved through mechanisms such as apoptosis induction, autophagy, cell cycle arrest, and disruption of the actin cytoskeleton.
Objective: Melanoma, the fastest-growing malignancy among young individuals in the United States and the predominant cancer among young adults aged 25 to 29, poses a significant health threat. This study aims to elucidate the apoptotic mechanism of CEG against the melanoma cancer cell line (A375).
Transcriptional profiling of exosomes derived from serum of patients with rare earth pneumoconiosis by RNA-sequencing and PI3K/Akt pathway is activated in lung of mice exposed to rare earth NdO.

Rare earth is used extensively around the world, and rare earth particles cause a respiratory disease in workers termed rare earth pneumoconiosis(REP) that have attracted considerable attention. However, the mechanisms of REP, characterized by diffuse pulmonary fibrosis, are elusive. REP progression involves various signaling pathway networks comprising numerous cell types and cytokines.

This study assessed the feasibility of miR17 ~ 92-based antiresorptive strategy by determining the effects of conditional transgenic (cTG) overexpression of miR17 ~ 92 in myeloid cells on bone and osteoclasts. Osteoclasts of male and female cTG mutant mice each showed 3- to fivefold overexpression of miR17 ~ 92 cluster genes compared to those of age- and sex-matched wildtype (WT) littermates. Male but not female cTG mutant mice had more trabecular and cortical bones as well as lower bone resorption reflected by reduction in osteoclast number and resorbing surface.
