Bladder cancers develop from the epithelial lining of the urinary bladder. cannabinoid receptors in the human Bladder Cancer cells could be targeted to treat the disease, but more research is needed in this field.

Literature Discussion: 

Several research groups are studying the potential treatment of cannabinoids in Bladder Cancer.

Until now, we know that human bladder cells express the cannabinoid receptors CB1, CB2 and GPR55 (Bakali et al., 2014).

CB2 receptors are upregulated in human Bladder Cancer (BC) cells RT4 and RT112. Activation of CB2 with synthetic cannabinoid agonist JWH015 induced cytotoxicity in BC and changes in cellular sphingolipids metabolism (Bettiga et al., 2017).

2AG regulates inflammation and proliferation processes of bladder carcinoma cells, probably through CB receptors (Gasperi et al., 2014).
