Mrs. Cronan died the next year, of multiple carcinoma at 54.
Several filopodia-inducing proteins such as the molecular motor myosin-X (MYO10) or the actin-bundling protein fascin promote cancer cell invasion both in vitro and in mouse models and are associated with poor patient prognosis in multiple carcinoma types8,13,14.
Epidermal growth factor receptor (EGFR) has been proved to be related with the pathogenesis and progression of multiple carcinoma types, including lung cancer [1], breast cancer [2], prostatic cancer [3] and pancreatic cancer [4].
Further studies of the promigratory role of MAP4K4 showed that the knockdown of this transcript inhibited the migration of multiple carcinoma cell lines, indicating a broad role in cell motility and potently suppressed the invasion of SKOV-3 cells in vitro.
Instead, promoter methylation of OPCML was frequently detected in multiple carcinoma cell lines (nasopharyngeal, esophageal, lung, gastric, colon, liver, breast, cervix, prostate), lymphoma cell lines (non-Hodgkin and Hodgkin lymphoma, nasal NK/T-cell lymphoma) and primary tumors, but not in any non-tumor cell line and seldom weakly methylated in normal epithelial tissues.
It was found that OPCML-v1 expression was dramatically reduced or completely silenced in multiple carcinoma cell lines of nasopharynx, esophagus, breast, cervix, stomach, lung, colon, liver and prostate, as well as in virtually all lymphoma cell lines examined (Fig. 2C and Figure S1), but readily detected in glioma cell lines (Fig. 2D).
Protocadherin-10 (PCDhas) has been identified as a tumor suppressor gene in multiple carcinomas.
On exposure to such radiation the skin erupts into numerous pigmented spots, resembling freckles, which tend to develop into multiple carcinomas.
Our present study further verifies that OPCML can function as a broad TSG and is frequently inactivated epigenetically in multiple carcinomas and lymphomas, including NPC, esophageal, lung, gastric, hepatocellular, colorectal, breast, cervical and prostate carcinomas.
Recent data suggest that an increased in PDE-5 expression is linked with the modulation of certain enzymes involved in the proliferation and antiapoptotic mechanisms observed in multiple carcinomas.
Downregulation of let-7 family members is observed in multiple carcinomas [ 20], including colon cancer [ 21].
