Anti-proliferative and anti-angiogenic effects of CB2R agonist (JWH-133) in non-small lung cancer cells (A549) and human umbilical vein endothelial cells: an in vitro investigation.

 

“Non-small cell lung cancer has one of the highest mortality rates among cancer-suffering patients. It is well known that the unwanted psychotropic effects of cannabinoids (CBs) are mediated via the CB(1) receptor (R), and selective targeting of the CB(2)R would thus avoid side effects in cancer treatment…

the aim of our study was to evaluate the effect of selective CB(2)R agonist, JWH-133, on A549 cells (non-small lung cancer) and human umbilical vein endothelial cells (HUVECs)…

The present study demonstrates the in vitro anti-proliferative and anti-angiogenic potential of CB(2)R agonist, JWH-133, in nonsmall lung cancer cells and HUVECs.

Our results generate a rationale for further in vivo efficacy studies with this compound in preclinical cancer models.”

Cannabinoid Receptors, CB1 and CB2, as Novel Targets for Inhibition of Non-Small Cell Lung Cancer Growth and Metastasis

“Cannabinoid receptors are expressed in human lung cancers”

 

  “Recently, CB1 and CB2 have been shown to be overexpressed on tumor cells compared to normal cells in various types of cancers, such as breast and liver, and therefore could be used as novel targets for cancer. In addition, several cannabinoids, including THC and cannabidiol, synthetic cannabinoid-agonists JWH-133, Win55,212-2, were shown to inhibit tumor growth and progression of several types of cancers, including glioma, glioblastoma multiforme, breast, prostate, colon carcinomas, leukemia and lymphoid tumors.”

“There are three general types of cannabinoids: phytocannabinoids, THC and cannabidiol, are derived from plants; endogenous cannabinoids, 2AG and AEA, which are produced inside the body; and synthetic cannabinoids, JWH-133/JWH-015, CP-55 and Win55,212-2.”

“Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide; however, only limited therapeutic treatments are available. Hence, we investigated the role of cannabinoid receptors, CB1 and CB2, as novel therapeutic targets against NSCLC…”

“These results suggest that CB1 and CB2 could be used as novel therapeutic targets against NSCLC.”
