Keratin, type II cytoskeletal 7 also known as cytokeratin-7 (CK-7) or keratin-7 (K7) or sarcolectin (SCL) is a protein that in humans is encoded by the KRT7 gene. [5] [6] [7] Keratin 7 is a type II keratin. It is specifically expressed in the simple epithelia lining the cavities of the internal organs and in the gland ducts and blood vessels.
In 2006 a new systematic nomenclature for mammalian keratins was created, and the proteins previously called cytokeratins are simply called keratins (human epithelial category). For example, cytokeratin-4 (CK-4) has been renamed keratin-4 (K4). [3] However, they are still commonly referred to as cytokeratins in clinical practice.
SGc tumor cells stain positive with epithelial membrane antigen (EMA), cytokeratin -7 (CK-7), Ber-EP4, adipophilin, perilipin, and androgen receptor (AR). [6] [17] [2] Meanwhile, SGc cells are negative for carcinoembryonic antigen (CEA), gross cystic disease fluid protein, and S100 protein, helping differentiate SGc from SCC and BCC.
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
- The right panel shows high magnification on a positive area, confirming adenocarcinoma, as it shows tumor cells with large nuclei and prominent nucleoli. AE1/AE3 is an antibody cocktail that is used in immunohistochemistry , being generally positive in the cytoplasm of carcinomas (cancers of epithelial origin).
An ideal tumor marker does not exist, and how they are clinically applied depends on the specific tumor marker. For example, tumor markers like Ki-67 can be used to choose form of treatment or in prognostics but are not useful to give a diagnosis, while other tumor markers have the opposite functionality. Therefore it's important to follow the ...

Cyclin D1 and CK5/6 staining could be used in concert to distinguish between the diagnosis of papilloma (Cyclin D1 < 4.20%, CK 5/6 positive) or papillary carcinoma (Cyclin D1 > 37.00%, CK 5/6 negative). [2] In the lung, distinguishing epithelioid mesothelioma (CK5/6 positive in 83%) from lung adenocarcinoma (CK5/6 negative in 85%). [1]
