The proapoptotic and antineoplastic properties of cannabinoids with emphasis on effects of N-acylethanolamines were analyzed. Cannabinoids enhanced apoptotic and necrotic processes in many types of tumour cells and tissues. Involvement of different types of receptors and signaling pathways in mediating the proapoptotic effects of cannabinoids are discussed. The evidences in favour of both proap...

RNA interference using small interfering RNA (siRNA) is an effective means of silencing gene expression in cells. Intradermal administration of nucleic acids via gene gun represents an efficient method for delivering nucleic acids to professional antigen-presenting cells in vivo. In this study, we show that the coadministration of DNA vaccines encoding human papillomavirus type 16 E7 with siRNA...

Human telomerase is highly active in more than 85% of primary cancers, regardless of their tissue origins, but not in most differentiated somatic tissues. Because of this, telomerase recently has become a popular target of anticancer therapy and has been used as a marker of cancer. Similarly, telomerase promoters, especially telomerase reverse transcriptase (TERT) promoter, have been zealously ...

The FAS (TNFRSF6/CD95/APO-1) gene is silenced in many tumor types, resulting in an inability to respond to proapoptotic signals. The FAS promoter is polymorphic, including a G to A substitution at -1377 bp and an A to G substitution at -670 bp, which occur within SP1 and signal transducers and activators of transcription 1 transcription factor binding sites, respectively. In a case-control stud...

The E2F1 transcription factor is a critical downstream target of the tumor suppressor RB. When activated, E2F1 can induce cell proliferation and/or apoptosis. In addition, E2F1 overexpression sensitizes cancer cells to chemotherapeutic drugs. In a screen for genes that are regulated synergistically by E2F1 and chemotherapy in cancer cells, we identified the proapoptotic tumor suppressor gene ma...
