“Cannabinoid receptor-1 (CB1) represents a potential drug target against conditions that include obesity and substance abuse. However, drug trials targeting CB1 (encoded by the CNR1 gene) have been compromised by differences in patient response.
Towards addressing the hypothesis that genetic changes within the regulatory regions controlling CNR1 expression contribute to these differences, we characterised the effects of disease associated allelic variation within a conserved regulatory sequence (ECR1) in CNR1 intron 2 that had previously been shown to modulate cannabinoid response, alcohol intake and anxiety-like behaviour.
We used primary cell analysis of reporters carrying different allelic variants of the human ECR1 and found that human specific C-allele variants of ECR1 (ECR1(C)) drove higher levels of CNR1prom activity in primary hippocampal cells than did the ancestral T-allele and demonstrated a differential response to CB1 agonism.
We further demonstrate a role for the AP-1 transcription factor in driving higher ECR1(C) activity and evidence that the ancestral t-allele variant of ECR1 interacted with higher affinity with the insulator binding factor CTCF. The cell-specific approaches used in our study represent an important step in gaining a mechanistic understanding the roles of non-coding polymorphic variation in disease and in the increasingly important field of cannabinoid pharmacogenetics.”
“Obesity, an important risk factor for developing chronic kidney disease (CKD), affects the kidneys by two main molecular signaling pathways: the endocannabinoid/CB1 R system, whose activation in obesity promotes renal inflammation, fibrosis, and injury; and the inducible nitric oxide synthase (iNOS), which generates reactive oxygen species resulting in oxidative stress. Hence, a combined peripheral inhibitory molecule that targets both CB1 R and iNOS may serve as an efficacious therapeutic agent against obesity-induced CKD.
“Small molecules targeting peripheral CB1 receptors have therapeutic potential in a variety of disorders including obesity-related, hormonal and metabolic abnormalities, while avoiding the psychoactive effects in the CNS.
“Obese individuals are more likely to show insulin resistance (IR). However, limited population studies on

“Healthy aging includes freedom from disease, ability to engage in physical activity, and maintenance of cognitive skills for which diet is a major lifestyle factor. Aging, diet, and health are at the forefront of well-being for the growing population of older adults with the caveat of reducing and controlling pain. Obesity and diabetes risk increase in frequency in adults, and exercise is encouraged to control weight, reduce risk of type II diabetes, and maintain muscle mass and mobility.
