CD9, a member of the tetraspanin family, plays important roles in a variety of cell activities.
Fibrosarcoma is a malignant tumor that arises from fibroblasts. Low CD9 expression is found …

Purpose CD81 is a member of the tetraspanin family of membrane proteins. Recently, it has
been shown that CD81 may be involved in cancer cell proliferation and metastasis. As yet …

Expression of tetraspanin CD9 protein is downregulated in many tumors. CD9 over-
expression also reduces the tumorigenicity of some human cancer cells. Here, we …

Tumor cell metastasis, a process which increases the morbidity and mortality of cancer
patients, is highly dependent upon matrix metalloproteinase (MMP) production. Small …

BACKGROUND: The tetraspanin transmembrane protein CD9 is known to be involved in
cell adhesion, proliferation, and cell motility. Previous studies have reported that reduced …

CD9 is a member of the tetraspanins, and has been shown to be involved in a variety of
cellular activities such as migration, proliferation, and adhesion. In addition, it has been …

The implication of the tetraspanin CD9 in cancer has received much recent attention and an
inverse correlation between CD9 expression and the metastatic potential and cancer …

Small cell lung cancer (SCLC) invades locally and metastasizes distantly extremely early
when compared with nonsmall cell lung cancer (NSCLC). The underlying molecular …

Tumor cells counteract innate and adaptive antitumor immune responses by recruiting
regulatory T cells (Treg) and innate myeloid-derived suppressor cells (MDSC), which …

CD24 (cluster of differentiation 24) is a small heavy glycosylated protein, which is
overexpressed in many cancer and some cancer stem cells and is associated with the …
