Cisplatin is a potent platinum-based anticancer drug approved by the Food Drug Administration (FDA) in 1978. Despite its advantages against solid tumors, cisplatin confers toxicity to various tissues that limit clinical uses.

Tea polyphenols (TP) possess the ability to regulate dyslipidemia and gut microbiota dysbiosis. However, underlying mechanism is still elusive. The present study explored intervention of TP on high fat diet induced metabolic disorders, dysbiosis in mice, intestinal mechanism. As a result, significantly ameliorated hyperlipidemia, improved expression levels hepatic lipid metabolism genes, modulated microbiota. was supposed rely maintaining redox state by TP. Intestinal related indicators were correlated with distribution An unidentified genus Lachnospiraceae, Bacteroides, Alistipes, Faecalibaculum identified as biomarkers for state. Importantly, different dosages varied patterns, an overdose intake attenuated beneficial effects health. Our findings offered novel insights into homeostasis.

Some coronavirus disease 2019 (COVID-19) patients develop acute pneumonia which can result in a cytokine storm syndrome response to Severe Acute Respiratory Syndrome 2 (SARS-CoV-2) infection. The most effective anti-inflammatory drugs employed so far severe COVID-19 belong the cytokine-directed biological agents, widely used management of many autoimmune diseases. In this paper we analyze efficacy epigallocatechin 3-gallate (EGCG), abundant ingredient green tea leaves and well-known antioxidant, counteracting diseases, are dominated by massive cytokines production. Indeed, studies registered that EGCG inhibits signal transducer activator transcription (STAT)1/3 nuclear factor kappa-light-chain-enhancer activated B cells (NF-κB) factors, whose activities crucial multiplicity downstream pro-inflammatory signaling pathways. Importantly, safety EGCG/green extract supplementation is well documented clinical trials, as discussed review. Since restore natural immunological homeostasis different propose here therapy with patients. Besides some antiviral anti-sepsis actions, major benefits lie its anti-fibrotic effect ability simultaneously downregulate expression inflammatory mediators. conclusion, be considered potential safe supplement counteract hyper-inflammation growing COVID-19.

Tea is particularly rich in polyphenols, including catechins and theaflavins, thearubigins, flavonols, phenolic acids, which are believed to contribute the health benefits of tea. The health-promoting effects tea polyphenols be related their cellular defensive properties. This review intended briefly summarize relationship between chemical structures biological activities. appear as direct antioxidants by scavenging reactive oxygen/nitrogen species; chelating transition metals; inhibiting lipid, protein, DNA oxidations. They also act directly suppressing "pro-oxidant" enzymes, inducing endogenous antioxidants, cooperating with vitamins. Moreover, regulate signaling transduction pathways, importantly contributing prevention chronic diseases promotion physiological functions. Apparently, features closely associated antioxidant potentials.
