چکیده مقاله:

Chronic lymphocytic leukaemia (CLL) is the most common B-cell malignancy in the western world and exists as subtypes with very different clinical courses. Myeloid cell leukemia 1 (Mcl-1) is one member of Bcl-2 family proteins that has been shown to be expressed in various tissues and malignant cells, including CLL, where its expression is significantly associated with a failure to achieve complete remission following cytotoxic therapy. Induction of apoptosis by prenylated coumarin, umbelliprenin, in Jurkat cells was previously shown. We examined whether umbelliprenin can down-regulate Mcl-1 gene and protein in Jurkat cells. In this regard cells were incubated by umbelliprenin, and then down- regulation of Mcl-1 gene was studied by Real Time PCR method. Moreover, down-regulation of Mcl-1 protein was studied by western blot analysis. We showed that, expression of Mcl-1 mRNA was increased from 1 hour to 3 hours incubation٫ but this increase has a scale down pattern. Moreover umbelliprenin could inhibit Mcl-1 protein. In conclusion umbelliprenin treatment modulates Mcl-1 expression at both the transcriptional and posttranslational levels.

Mcl-1 Expression Is Up-Regulated in Malignancies of the Parotid Gland

The anti-apoptotic protein Mcl-1 is highly expressed in various types of malignant tumors. Overexpression is reported to correlate with poor prognosis and disease progression. We report the expression levels of Mcl-1 in tumor samples of the parotid gland. A retrospective study containing 108 patients was performed. A tissue microarray of six malignancies of the parotid gland and pleomorphic ade...

Umbelliprenin from Ferula szowitsiana Activates both Intrinsic and Extrinsic Pathways of Apoptosis in Jurkat T-CLL Cell Line

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...
