Apoptotic enteropathy is a histological finding of increased crypt apoptosis that is commonly associated with diarrhea. Several etiologies for this disease state including immunodeficiency, autoimmune, infection, hereditary, checkpoint inhibitors, immunosuppressants, and immunomodulators have been previously described. We describe an extremely rare case of a patient with marginal cell lymphoma treated with bendamustine, rituximab, and obinutuzumab presenting with severe, relapsing, chronic diarrhea with persistent apoptotic enteropathy of unknown etiology, despite hematological remission and discontinuation of treatment for 1 year.

Purpose: This study aims to elucidate the roles of the PI3K-Akt signaling pathway and enterocyte apoptosis in necrotizing enterocolitis (NEC) pathogenesis and investigate the impact of vitamin A intervention on these factors.
Methods: We employed an NEC mouse model and administered vitamin A treatment. Retinol levels in mouse blood were quantified using ELISA.

Thymoquinone (TQ), a bioactive compound derived from , has garnered significant attention for its potential as a natural anti-cancer agent, particularly in the context of colorectal cancer. This review provides a detailed synthesis of the current literature on the anti-cancer properties of TQ in colorectal cancer cells, exploring both in vitro and in vivo studies to elucidate its mechanisms of action. TQ effectively induces apoptosis, inhibits cell proliferation, and reduces metastasis in colorectal cancer cells by modulating key molecular pathways such as PI3K/AKT/mTOR, NF-κB, STAT3, and MAPK.

The CDK4/6 inhibitor Ribociclib has shown limited efficacy as a monotherapy in colorectal cancer (CRC). However, combining Ribociclib with targeted therapies could present a viable strategy for treating CRC. This study evaluated the combination of Ribociclib and the PI3K inhibitor Alpelisib across four distinct cell lines representing different mutational statuses ( wild-type, -mutated, -mutated, and -mutated).

Nonsteroidal anti-inflammatory drugs (NSAIDs) can induce serious adverse effects in gastrointestinal (GI) mucosa, increasing intestinal permeability and leading to mitochondrial dysfunction, oxidative stress, apoptosis and inflammation. As proton pump inhibitors are effective in protecting against NSAID-induced gastropathy but not NSAID-induced enteropathy, current research is focused on natural products as protective substances for therapy and prevention of intestinal injury. Herein, through the use of an in vitro model based on intestinal epithelial cell (Caco-2) damage caused by indomethacin (INDO), we examined the protective activity of a commercially available standardized extract (OFI+OE) from (L.
