Membrane bound CLN2 protein co-immunoprecipitates with CLN3, CLN6 and CLN8 and co-localizes to early and/or recycling endosomes and lipid rafts. These interactive proteins underlie the clinical variants of neuronal ceroid lipofuscinosis and appear to occur at multiple points along a common pathway.

Postnatal exposure to glucocorticoids led to hyperlipidemia, increased hepatic triglyceride content and insulin resistance subsequently during the suckling phase in rats.

Hypoxic stress was associated with increased maternal and fetal rat plasma corticotrophin releasing factor (CRF) and corticosterone concentrations, while provoking meconium passage. A role for CRF in mediating hypoxic stress-mediated meconium passage is proposed.

Mice carrying mutations of the multi-drug resistance 4 gene developed hepatic dysfunction with significant bile duct proliferation, peribiliary fibroblast activation and fibrosis when fed a cholic acid supplemented diet. These changes reversed with a lecithin supplemented diet.

In a longitudinal prospective study, a month of treatment and folate supplementation altered the epithelial cellular and blood lymphocytic micronucleus frequency in patients with Crohn's disease and ulcerative colitis. These observations suggest a role for cytogenetic aberrations in the pathogenesis of these bowel diseases and may help predict the subsequent development of cancer.
