This phase II trial investigated the safety and efficacy of opaganib in combination with abiraterone or enzalutamide in patients with castration‐resistant prostate cancer (CRPC). While the study did not meet its disease control efficacy endpoint, there was evidence of clinical activity in a subset of patients.

Ceramide pathway is a key regulator in cell proliferation and apoptosis and oxidative stress up-regulate ceramides. Acid ceramidase (ACDase), neutral sphingomyelinase (NSMase) and glucosylceramide synthase (GCS) are critical enzymatic systems in ceramide

ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Discovery and Evaluation of Inhibitors of Human Ceramidase [PDF]
Abstract The ceramide/sphingosine-1-phosphate (S1P) rheostat has been hypothesized to play a critical role in regulating tumor cell fate, with elevated levels of ceramide inducing death and elevated levels of S1P leading to survival and proliferation.

Polyploid giant cancer cells (PGCC) represent a poorly understood, small subpopulation of tumor cells that are increasingly being recognized for their critical role in therapy resistance, metastasis, and cancer recurrence.

F13A1‐Mediated Macrophage Activation Promotes MASH Progression via the PKM2/HIF1A Pathway
In fatty liver disease, hepatocytes exposed to palmitate release S1P, which activates calcium signaling in macrophages. Elevated calcium enhances the activity of F13A1, driving PKM2 dimerization. The PKM2 dimers cause Warburg effect, translocate to the nucleus, cooperate with HIF1A, and upregulate IL1B expression, ultimately promoting classical ...

Dysbiosis in the Pathogenesis of Atopic Dermatitis
ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by epidermal barrier dysfunction and immune dysregulation. Recent research highlights cutaneous dysbiosis as a critical factor in its pathogenesis. In this review, we summarize the interplay between the skin microbiota and host immunity, contrasting the homeostatic ...

Activation of Ceramidase and Ceramide Kinase by Vanadate via a Tyrosine Kinase–Mediated Pathway
.: Ceramide, a key molecule in the metabolism of sphingolipids, is converted by ceramidase to sphingosine, and phosphorylated by ceramide kinase to form ceramide-1-phosphate (C1P). In this study, we improved on a method of thin-layer chromatography using

Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...
