The initiation and progression of colorectal cancer (CRC) are intimately associated with genetic, environmental and biological factors. (DSV), a sulfate-reducing bacterium, has been found excessive growth in CRC patients, suggesting a potential role in carcinogenesis. However, the precise mechanisms underlying this association remain incompletely understood.

MS4A (membrane-spanning 4-domain, subfamily A) molecules are categorized into tetraspanins, which possess four-transmembrane structures. To date, eighteen MS4A members have been identified in humans, whereas twenty-three different molecules have been identified in mice. MS4A proteins are selectively expressed on the surfaces of various immune cells, such as B cells (MS4A1), mast cells (MS4A2), macrophages (MS4A4A), Foxp3CD4 regulatory T cells (MS4A4B), and type 3 innate lymphoid cells (TMEM176A and TMEM176B).

The influence of metal elements on the biomedical activity of microalgal exopolysaccharides (EPS) remains underexplored. This study examined the antitumor properties of Botryococcus braunii EPS under high cobalt conditions and the role of exogenous 3-indole acetic acid (IAA) in enhancing its activity. Results showed that IAA mitigated cobalt-induced inhibition of B.

Tumor necrosis factor-alpha (TNF-α) is a pleiotropic cytokine with critical roles in inflammation, cell survival, and defense. As a member of the TNF superfamily, it exerts its effects by binding to transmembrane receptors and triggering various downstream signaling pathways. Although TNF-α's involvement in antiviral responses in mammals is well-established, its role in teleost remains poorly understood.

Upon injury, fibroblasts in the surrounding tissue become activated, migrating into the wound in a controlled manner. Once they arrive, they contract the wound and remodel the stroma. While certain cell surface receptors promote fibroblast migration, others cause repulsion between fibroblasts upon contact, seemingly opposing their clustering within the wound bed.
