Huanglian Ejiao Decoction Alleviates Ulcerative Colitis in Mice Through Regulating the Gut Microbiota and Inhibiting the Ratio of Th1 and Th2 Cells.

Background: Huanglian-ejiao decoction (HED) is a Chinese traditional medicinal formula evolved from the Shanghan Lun (Treatise on Febrile Diseases). However, HED ultimate mechanism of action remained indistinct. Therefore, this study aimed to investigate whether HED could exert anti-inflammatory effects on 2,4,6-Trinitrobenzenesulfonic acid (TNBS)-induced colitis (UC) model through the regulation of CD4T subsets and gut microbiota.

Targeting heparan sulfate proteoglycans as an effective strategy for inhibiting cancer cell migration and invasiveness compared to heparin.

By virtue of their ability to bind different growth factors, morphogens and extracellular matrix proteins, heparan sulfate proteoglycans (HSPGs) play a determinant role in cancer cell differentiation and migration. Despite a strong conceptual basis and promising preclinical results, clinical trials have failed to demonstrate any significant advantage of administering heparin to oncology patients. We exploited our anti-heparan sulfate branched peptide NT4 to test the opposite approach, namely, targeting HSPGs to interfere with their functions, instead of using heparin as a soluble competitor in human cell lines from pancreas adenocarcinoma, colon adenocarcinoma, rhabdomyosarcoma and two different breast cancers.
