The heparan sulfate sulfotransferase 3-OST3A (HS3ST3A) is a novel tumor regulator and a prognostic marker in breast cancer Mao X, Gauche C, Coughtrie MW, Bui C, Gulberti S, Merhi-Soussi F, Ramalanjaona N, Bertin-Jung I, Diot A, Dumas D, De Freitas Caires N, Thompson AM, Bourdon JC, Ouzzine M, Fournel-Gigleux S Heparan sulfate (HS) proteoglycan chains are key components of the breast tumor microenvironment that critically influence the behavior of cancer cells. It is established that abnormal synthesis and processing of HS play a prominent role in tumorigenesis, albeit mechanisms remain mostly obscure. HS function is mainl... |
ESCs require PRC2 to direct the successful reprogramming of differentiated cells toward pluripotency. Pereira CF, Piccolo FM, Tsubouchi T, Sauer S, Ryan NK, Bruno L, Landeira D, Santos J, Banito A, Gil J, Koseki H, Merkenschlager M, Fisher AG Embryonic stem cells (ESCs) are pluripotent, self-renewing, and have the ability to reprogram differentiated cell types to pluripotency upon cellular fusion. Polycomb-group (PcG) proteins are important for restraining the inappropriate expression of lineage-specifying factors in ESCs. To investigate whether PcG prot... |
