Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...

Melanoma has been reported a contemporary malignant cancer. Here, anti-cancer effects of sea cucumber extract (SCE) have been examined on melanoma cells and compared with dacarbazine. MTT assay and morphological analysis were performed to evaluate cytotoxic effects of methanolic SCE Also, several methods were exerted to detect cell dying by SCE and dacarbazine. The MTT assay showed that B16F10 ...

Background: The purpose of this study was to examine the impact of Insulin (INS) on human sperm function, in light of a recent proteomic analysis indicating that these cells express the INS receptor (INSR). Materials and Methods: We used Western blot and Immunocytochemical analyses. Results: Immunocytochemical analyses confirmed the presence of INSR in human spermatozoa and localized this recep...

During vertebrate retinogenesis, the precise balance between retinoblast proliferation and differentiation is spatially and temporally regulated through a number of intrinsic factors and extrinsic signaling pathways. Moreover, there are complex gene regulatory network interactions between these intrinsic factors and extrinsic pathways, which ultimately function to determine when retinoblasts ex...

Backgrounds: Hepatocellular carcinoma (HCC), Primary liver cancer, is the fifth most common cancer in men. Histone deacetylation causes chromatin condensation resulting gene silencing and tumorigenesis. These enzymes have become a novel target for treatment of cancer. deacetylase inhibitors (HDACIs) can reactivate tumor suppressor genes (TSGs) by inhibition histone deacetylases (HDACs) activity...

Mammalian target of rapamycin complex 2 (mTORC2), one of two different enzymatic complexes of mTOR, regulates a diverse set of substrates including Akt. mTOR pathway is one of well-known mediators of aging process, however, its role in skin aging has not been determined. Skin aging can be induced by physical age and ultraviolet (UV) irradiation which are intrinsic and extrinsic factors, respect...
