Moreover, green- synthesized zinc oxide nanoparticles (ZnO-NPs) using natural resources are one of the most promising therapeutic agents for anticancer therapy. Here we report the facile green synthesis and characterization of ZnO-NPs from Teucrium polium (TP-ZnO-NP) herb extract and the anticancer activities of these nanoparticles on gastric cancer cells.

miR-320a promotes p53-dependent apoptosis of prostate cancer cells by negatively regulating TP73-AS1 invitro.

TP73 antisense RNA 1 (TP73-AS1) is an oncogenic long non-coding RNA that is activated in several types of cancers. It has been shown that the activity of TP73-AS1 is controlled by several miRNAs, but post-transcriptional mechanisms that regulate TP73-AS1 activity in prostate cancer remain highly elusive. Accordingly, in the present study, we aimed to determine the miRNAs that are involved in the regulation of TP73-AS1 in prostate cancer and to show the effects of these molecules on the malignant proliferation of prostate cancer cells.

Cedrus libani tar prompts reactive oxygen species toxicity and DNA damage in colon cancer cells.

Background: Many chemotherapeutic drugs used in cancer treatment have anticancer properties by inducing reactive oxygen species (ROS). However, the same effect occurs in normal cells, limiting the availability of these drugs. Therefore, studies on the detection of new herbal anticancer agents that have selective effects on cancer cells are of great importance.
