一般說明
Mucin 4 (MUC4) is a transmembranous glycoprotein. MUC4 is expressed in the cytoplasm of certain epithelial surfaces, such as colonic, breast, and lung epithelia. An abnormal expression of MUC4 has been reported in various carcinomas of the colon, pancreas, breast, and ovaries.MUC4 is highly expressed in the vast majority of human pancreatic neoplasms, such as intraductal papillary mucinous neoplasia of the pancreas, pancreatic intraepithelial neoplasms and pancreatic ductal adenocarcinoma; however, it is not detected in the normal pancreas or in chronic pancreatitis.MUC4 is not expressed in normal bile ducts, but it can be overexpressed in intrahepatic cholangiocarcinoma and bile duct cholangiocarcinoma. MUC4 overexpression has been reported in low-grade fibromyxoid sarcoma (LGFMS). In this study a large cohort of LGFMS, all with FUS gene rearrangement confirmed by FISH, showed cytoplasmic staining for MUC4, usually in a strong and diffuse manner. Similarly, strong, diffuse cytoplasmic staining for MUC4 was identified in 78% (32/41) of cases of sclerosing epithelioid fibrosarcoma. MUC4 expression is also detected in the glandular component of biphasic synovial sarcomas (90%). Focal staining, usually interpreted as only scattered cells, was also seen in a subset of ossifying fibromyxoid tumors (29%), epithelioid GISTs (20%) and myoepithelial carcinomas (10%); whereas all other epithelioid soft tissue tumors—including clear cell sarcoma, epithelioid sarcoma, epithelioid hemangiosarcoma, PEComa and melanoma—were negative. It should be noted that various carcinomas may express MUC4, and therefore additional keratins or lineage-specific markers may be needed to exclude this possibility in some cases.

Mucins are members of an expanding family of large multifunctional glycoproteins. Pancreatic mucins have important biological functions, including the protection, lubrication, and moisturisation of the surfaces of epithelial tissues lining ductal structures within the pancreas. Several lines of evidence support

Mucins are high molecular weight glycoproteins that play important roles in carcinogenesis and tumor invasion. We have described, for the first time, that pancreatic ductal adenocarcinomas (PDACs) with an aggressive behavior and a poor outcome expressed MUC1 (pan-epithelial membrane-associated mucin)

Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive fibroblastic neoplasm that is characterized by alternating collagenous and myxoid areas, deceptively bland spindle cell morphology, a whorling architecture, and a t(7;16) translocation involving FUS and CREB3L2. Owing to variable morphology and a

Sclerosing epithelioid fibrosarcoma (SEF) is a rare aggressive fibroblastic neoplasm composed of cords of epithelioid cells embedded in a dense collagenous stroma. The reported immunophenotype of SEF is nonspecific. Some SEF cases show morphologic and molecular overlap with low-grade fibromyxoid
