AI Article Synopsis

  • Silymarin, a flavonoid from milk thistle, shows promising effects like antioxidant and anti-inflammatory properties, particularly in cancer research.
  • In a study on SPC212 human mesothelioma cells, silymarin was found to have a dose-dependent cytotoxic effect, with a half-maximal inhibitory concentration (IC) of about 187.5 µM.
  • The compound induced signs of apoptosis, such as cell shrinkage and nuclear changes, suggesting its potential as an anti-cancer agent that needs further investigation.

Article Abstract

Silymarin, a flavonoid complex isolated from Silybum marianum, possesses various biological properties, including antioxidant, anti-inflammatory, anti-glycation, and hepatoprotective effects. In the present study, we investigated the effects of silymarin on the SPC212 human mesothelioma cell line. MTT and neutral red assays were performed to examine the cytotoxic effects of silymarin. The apoptotic effect was investigated using AO/EB and DAPI staining, and morphological changes were observed using H&E and May-Grünwald staining. Additionally, immunocytochemistry was performed to detect Bax, Bcl2, and PCNA. Our results indicated that silymarin has a dose-dependent cytotoxic effect on SPC212 cells, with an IC value of approximately 187.5 µM. Silymarin induces apoptotic hallmarks such as apoptotic bodies, cell shrinkage, and nuclear condensation. In conclusion, silymarin demonstrated cytotoxic and apoptotic effects as well as morphological changes in SPC212 human mesothelioma cells. Further detailed studies are warranted to explore the potential of silymarin as an anti-cancer agent.

Acrylamide is broadly utilized in numerous areas with different purposes including being an additive, flocculating, sealing, dry strength improver and polymerizing agent, and so forth. Furthermore, it forms in certain food products at high temperatures. It poses serious hazard since its readily water-soluble and very reactive nature.

Background: To investigate the mechanism of action of stathmin1 (STMN1) in mesothelioma (MSM) and whether it has any role in its treatment.

Methods: STMN1 expression was examined using immunohistochemistry in biopsy tissues taken from MSM patients. The relationships between the levels of STMN1 expression in the pathology preparations of MSM patients, and the clinicopathological characteristics of these patients, and their survival times were investigated.

Astaxanthin (ASX) is one of the keto-carotenoids, which is biologically more active than other counterparts. Besides its variety of beneficial effects, it was reported to exert anticancer effects. Despite its utilization against different cancer types, the effect of ASX on mesothelioma has yet to be well-studied.

High blood levels of β-carotene and increased intake in the diets are inversely proportional to incidence of many cancer types. Antioxidant activity of β-carotene was proposed to be related with its antitumor effect. Despite this plant derivative substance being sought in many cancer types, the effectiveness of β-carotene against malignant mesothelioma remained unclear.
