HNF-1 binding point mutation of the AFP gene promotes cirrhosis in post-menopausal women.

Objective: α-fetoprotein (AFP) expression is activated during the embryonic stage or hepatocellular carcinogenesis, so it is presumed that AFP is a key endogenous molecule to promote cell proliferation or differentiation. We carried out gene screening in an unknown family with hyper-alpha-fetoproteinemia and some sporadic menopausal women, and discussed the relationship between AFP expression and liver cirrhosis.

Methods: Peripheral blood samples from family members, patients with malignant liver tumors, and normal controls were collected.

Antibodies to Type IV Collagen Induce Type 1 Autoimmune Pancreatitis.

Type 1 autoimmune pancreatitis (AIP) is prototypic autoantibody-mediated diseases. Sclerosis accompanied by fiber deposition is generally regarded as the primary lesion in the development of obliterative vasculitis. However, why collagens or their antibodies play a crucial role in the pathogenesis of AIP has not been demonstrated.
