Cancer

Mammalian epidermis, which is composed of hair follicles, sebaceous glands, and interfollicular epidermis, is maintained by discrete stem cells. In vivo lineage tracing demonstrated that murine LGR5 cells are mainly responsible for hair follicle regeneration whereas LGR6 cells generate sebaceous glands and interfollicular epidermis. However, little is known about their expression in the human skin tumors.

Abstract

Pancreatic ductal adenocarcinoma (PDAC) is a major cause of cancer death; identifying PDAC enablers may reveal potential therapeutic targets.

Human Papillomavirus (HPV) is known as causative for squamous cell carcinoma (SCC) of the oropharynx, but is also not infrequently found in carcinomas of the sinonasal tract. Recently, a subset of these carcinomas was recognized to harbour HPV33 and have a significant morphological overlap with adenoid cystic carcinoma (ACC), a rare and aggressive carcinoma originating in the minor salivary glands.

Cancer associated fibroblasts (CAFs) are the dominant cell population in the cancer stroma. Gremlin 1 (GREM1), an antagonist of the bone morphogenetic protein pathway, is expressed by CAFs in a variety of human cancers. However, its biological significance for cancer patients is largely unknown. We applied RNA in situ hybridization (ISH) to evaluate the prognostic value of stromal GREM1 expression in a large cohort of 670 colorectal cancers (CRCs).

AIMS:

Estrogen receptor α (ERα) plays a significant role in the development of breast cancer and has been used clinically as an endocrine therapeutic target. Currently, clinical laboratories use immunohistochemistry (IHC) to determine the ERα status of patients in order to distinguish those who would benefit from endocrine therapy. This method is highly subjective, requires a large amount of tumor tissue, and may generate false-negative results.
