Maintaining the proteome is crucial to retaining cell functionality and response to multiple intrinsic and extrinsic stressors. Protein misfolding increased the endoplasmic reticulum (ER) stress and activated the adaptive unfolded protein response (UPR) to restore cell homeostasis. Apoptosis occurs when ER stress is prolonged or the adaptive response fails.

The main objective of this study was to investigate the hepatoprotective potency of the methanol extract against CCl-induced liver damage in rats. HPLC technique was used to estimate the presence of polyphenols in the methanol extract of (PCM), while proximate analysis revealed the presence of carbohydrates, lipids, and moisture in the extract. The antioxidant potential of PCM was evaluated by 2,2-diphenylpicrylhydrazyl (DPPH) and reducing power assay, which showed a high percentage of inhibition against free radicals.

Carbon dots (CDs) are a new category of crystalline, quasi-spherical fluorescence, "zero-dimensional" carbon nanomaterials with a spatial size between 1 nm to 10 nm and have gained widespread attention in recent years. Green CDs are carbon dots synthesised from renewable biomass such as agro-waste, plants or medicinal plants and other organic biomaterials. Plant-mediated synthesis of CDs is a green chemistry approach that connects nanotechnology with the green synthesis of CDs.

Launaea procumbens methanol extract (LPME) was evaluated against carbon tetrachloride (CCl4)-induced pancreatic oxidative damage and hyperglycemia in rats. Various doses of the extract were administered to rats after 48 h of CCl4 treatment (3 ml/kg bodyweight (bw); intraperitoneally, 20% CCl4/olive oil) twice a week for 4 weeks. Coadministration of various concentrations of LPME (100, 150 and 200 mg/kg) ameliorated the toxicity of CCl4 and reversed the serum level of enzymes (amylase and lipase), glucose and hormone (insulin).
