Petroselinum crispum extract increased bcl-2 and M1 receptor expression while also lowering caspase-3/-9, bax, AChE activity, and malondialdehyde (MDA) levels in the hippocampus and frontal cortex, indicating neuroprotective effects of plant extract against a scopolamine-induced Alzheimer’s -disease (AD) rat model [58]. Here, BCL2 is linked to Alzheimer disease.
