Prostate cancer, one of the most prevalent malignancies afflicting men globally, remains a significant health concern, with millions diagnosed each year. According to recent studies, over 1.4 million men receive a prostate cancer diagnosis annually, and sadly, approximately 375,000 succumb to this disease. The pressing need for more effective treatments has led to groundbreaking research, including a recent study investigating the potential of cannabis sativa extract, cannabidiol, and cisplatin in combating prostate cancer cells, specifically PC3.
To find out if cannabis compounds could be better for treating prostate cancer, the researchers used various methods. They looked at how different amounts of Cannabis sativa extract, cannabidiol, and cisplatin affected PC3 cells using the MTT assay, a common test for cancer cell growth. They also used advanced xCELLigence technology to track cell responses in real-time on a special plate.
Additionally, they checked for apoptosis, which is programmed cell death, by measuring caspase 3/7 activity in a 96-well plate after treatment. They also used Western blot and qRT-PCR to see how genes like p53, Bax, and Bcl2 were affected.
To get a complete picture, they studied the growth of PC3 tumors in mice, which helped them see how the compounds worked in living organisms.
The study's results strongly suggest that Cannabis sativa extract, cannabidiol, and cisplatin could be effective against prostate cancer.
These compounds were found to slow down the growth of PC3 cancer cells by activating caspase 3/7 activity, a crucial discovery that shows their ability to stop cancer cell growth.

Importantly, the study also revealed that these compounds induced programmed cell death (apoptosis) in cancer cells when a specific protein called retinoblastoma binding protein 6 (RBBP6) was silenced. This was associated with increased p53 and Bax mRNA expression and decreased Bcl2 gene expression, all of which indicate a desirable outcome in cancer therapy.
Additionally, in experiments with mice, the researchers noted a significant reduction in tumor growth when treated with cisplatin and cannabidiol. This further supports the potential effectiveness of these compounds in treating prostate cancer.
This groundbreaking study underscores the potential of cannabidiol as a viable therapy for prostate cancer, particularly when combined with RBBP6. The findings suggest that cannabidiol, rather than Cannabis sativa, may play a pivotal role in reducing the progression of this devastating disease.
This research marks an important step forward in the quest for more effective and less harmful treatments for prostate cancer, offering hope to the millions of individuals affected by this condition worldwide. As scientists continue to unravel the therapeutic potential of cannabis compounds, it opens the door to a new era of cancer treatment possibilities.
