5HT, Serotonin: Click to Expand ⟱
Source:
Type:
Serotonin (5-hydroxytryptamine or 5-HT) is best known as a neurotransmitter; however, it also plays diverse roles in peripheral tissues, including modulation of cell proliferation, angiogenesis, and immune responses.

Several studies have identified the expression of multiple 5-HT receptors (e.g., 5-HT1A, 5-HT2A, and 5-HT7) in breast cancer cells.
Serotonin may promote tumor cell proliferation and can influence breast cancer progression through receptor-mediated signaling pathways.

Expression of 5-HT and its receptors is documented in various cancers including breast, colorectal, pancreatic, prostate, and hepatocellular carcinoma.
Overexpression of particular 5-HT receptors often correlates with increased cell proliferation, angiogenesis, and metastatic potential.
High levels of 5-HT receptor expression generally serve as a marker for poor prognosis, although the exact prognostic implications vary depending on the specific receptor subtype and tumor type.

-Vomiting caused by chemotherapy was thought to result from the fact that the chemotherapeutics stimulated the secretion of 5-HT in intestinal chromaffin cells, and then 5-HT acted on 5-HT receptor which caused excitation of nerves and vomiting reflex.

*memory↑, exhibited a wide range of in vitro and in vivo neuropharmacological effects, including memory enhancement, anxiolytic, tranquilizing, anti-depressant, anti-stress
*neuroP↑, neurodegenerative, anti-inflammatory, anti-oxidant, analgesic, sedative, anti-convulsant, and Alzheimer's disease-reversing effects.
*Inflam↓,
*5HT↑, and increasing serotonin concentration in synapses.

4206- SIL,    Silymarin ameliorates experimentally induced depressive like behavior in rats: Involvement of hippocampal BDNF signaling, inflammatory cytokines and oxidative stress response
- in-vivo, NA, NA
*BDNF↑, improved BDNF expression, 5-HT, DA, NE and antioxidant paradigms in cerebral cortex as well as hippocampus.
*5HT↑,
*antiOx↑,
*IL6↓, silymarin attenuated IL-6, and TNF-α significantly in hippocampus and cerebral cortex in OBX rats.
*TNF-α↓,
*Mood↑, silymarin exhibits anti-depressant-like activity in OBX rats due to alterations in several neurotransmitters, endocrine and immunologic systems, including BDNF, 5-HT, DA, NE, MDA formation, IL-6, and TNF-α in hippocampus

4205- SIL,    The Therapeutic Effect of Silymarin and Silibinin on Depression and Anxiety Disorders and Possible Mechanism in the Brain: A Systematic Review
- Review, AD, NA
*BDNF↑, Silymarin and silibinin upregulated brain-derived neurotrophic factor (BDNF) and improved neural stem cells (NSCs) proliferation in the cortex and hippocampus.
*5HT↑, They also increased neurochemical serotonin (5-HT), dopamine (DA), and norepinephrine (NE) levels.
*MDA↓, Silymarin and silibinin reduced malondialdehyde (MDA) formation and increased glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activities.
*GSH↑,
*SOD↑,
*Catalase↑,
*IL6↓, silymarin and silibinin reduced interleukin (IL)-6, IL-1β, and IL-12β, reducing tumor necrosis factor α (TNF-α) induced neuroinflammation.
*IL1β↓,
