Summary of "TGFαL3-SEB fusion protein as an anticancer against ovarian cancer."

TGFαL3-SEB is a new synthetic fusion protein produced by the combination of the third loop of transforming growth factor with staphylococcal enterotoxin type B. In the current study, the anti-tumor effects of TGFαL3-SEB were evaluated against SKOV3 cells, which highly expressed the epidermal growth factor receptor (EGFR). Our findings showed that incubation of SKOV3 cells with 75, 100 and 150 μg/ml of TGFαL3-SEB significantly reduces the proliferation rate in a concentration-dependent manner (P < 0.05) and its IC50 value was 110 μg/ml. Caspase-3 activity was increased from 100% for control cells to 109, 144, and 169% for 75, 100 and 150 μg/ml of TGFαL3-SEB treatment, respectively. Caspase-9 activity and bax/bcl-2 ratio were also confirmed the apoptosis induction ability of TGFαL3-SEB (P < 0.001). Flow cytometry examination also showed that apoptosis was induced and the number of apoptotic cells was increased from 8.2% in un-treated cells to 20.9, 50, and 90% in response to 75, 100 and 150 μg/ml of TGFαL3-SEB fusion protein in a concentration-dependent manner (P < 0.05). The mRNA expression level of VEGF was also reduced to 0.89, 0.69, and 0.60, respectively in response to 75, 100 and 150 μg/ml of TGFαL3-SEB fusion protein exposure, respectively (P < 0.5). In summary, the findings of our study uncovered that TGFαL3-SEB fusion protein induced apoptosis and reduced angiogenesis in SKOV3 ovarian cancer cells in a concentration-dependent manner. This protein has the potential to act against EGFR expressing malignant cells to serve as a pro-apoptotic and angiogenesis blocker agents; however, further studies are needed to confirm its ability.

Medical and Biotech [MESH] Definitions

Autosomal dominant HEREDITARY CANCER SYNDROME in which a mutation most often in either BRCA1 or BRCA2 is associated with a significantly increased risk for breast and ovarian cancers.

A homolog of p53 TUMOR SUPPRESSOR PROTEIN that encodes full-length trans-activating and N-terminally-truncated (DeltaN) isoforms. Detection of splice variants and isoforms in the nervous system (human TELENCEPHALON, CHOROID PLEXUS; CEREBROSPINAL FLUID), embryonic tissue, human BREAST CANCER; OVARIAN CANCER, suggest roles in cellular differentiation.

A large, nuclear protein, encoded by the BRCA2 gene (GENE, BRCA2). Mutations in this gene predispose humans to breast and ovarian cancer. The BRCA2 protein is an essential component of DNA repair pathways, suppressing the formation of gross chromosomal rearrangements. (from Genes Dev. 2000;14(11):1400-6)

A heterodimeric protein that is a cell surface antigen associated with lymphocyte activation. The initial characterization of this protein revealed one identifiable heavy chain (FUSION REGULATORY PROTEIN 1, HEAVY CHAIN) and an indeterminate smaller light chain. It is now known that a variety of light chain subunits (FUSION REGULATORY PROTEIN 1, LIGHT CHAINS) can dimerize with the heavy chain. Depending upon its light chain composition a diverse array of functions can be found for this protein. Functions include: type L amino acid transport, type y+L amino acid transport and regulation of cellular fusion.

The in vitro fusion of GENES by RECOMBINANT DNA techniques to analyze protein behavior or GENE EXPRESSION REGULATION, or to merge protein functions for specific medical or industrial uses.
