One of the earliest steps in animal embryogenesis involves establishing the identity of embryonic structures and tissues from head to tail along the anterior-posterior axis. Hox genes encode a family of proteins that have a prominent and broadly conserved role in laying out this developmental roadmap in most animals. For some time, it’s been felt that Hox function was fairly well understood: a ...

BACKGROUND It is known that some patients with clinical, histological, and laboratory features of primary biliary cirrhosis (PBC) lack serum antimitochondrial antibodies (AMAs). In Asian countries, clinical information regarding AMA-negative PBC is still limited. In this report, we reviewed our patients with AMA-negative PBC in order to further understand this disease. METHODS Clinical featur...

Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease characterized by inflammatory destruction of the intrahepatic bile ducts. The differential diagnosis for PBC often includes autoimmune hepatitis (AIH). Both diseases can show prominent plasma cells and other overlapping histologic features. It is interesting that both diseases can involve elevated levels of serum immunoglobu...

Based on biculturalism theory (LaFromboise, Coleman, & Gerton, 1993), the present study examined the direct effect of perceived bicultural competence (PBC) on depressive symptoms, and PBC as a potential coping resource to moderate the association between minority stress and depressive symptoms. Participants were 167 Asian American, African American, and Latino/a American students at a predomina...

INTRODUCTION Both primary biliary cirrhosis (PBC) and Wilson's disease (WD) can cause copper retention in the liver, which is an important factor for liver cellular damage. Copper chelation may preserve liver cell function. It is challenging to distinguish WD from copper accumulation in patients with PBC. There have been few case reports of PBC co-occurrence with WD. CASE PRESENTATION Here we...

BACKGROUND Primary biliary cirrhosis (PBC) is an immune-mediated chronic cholestatic liver disease, characterized by increased concentrations of serum IgM and the presence of circulating anti-mitochondrial antibodies. Although bone diseases such as osteoporosis or osteodystrophy are commonly associated with PBC, osteomalacia which is caused by abnormal vitamin D metabolism, mineralization defec...

Genetic and environmental factors have been widely suggested to contribute to the pathogenesis of primary biliary cirrhosis (PBC), an autoimmune disease of unknown etiology leading to destruction of small bile ducts. Interestingly, epidemiologic data indicate a variable prevalence of the disease in different geographical areas. The study of clusters of PBC may provide clues as to possible trigg...

BACKGROUND Autoantibodies to the human muscarinic acetylcholine receptor of the M3 type (hmAchR M3) have been suggested to play an etiopathogenic role in Sjögren's syndrome. Primary biliary cirrhosis (PBC) often is associated with this syndrome. Therefore, we studied the co-presence of hmAchR M3 autoantibodies in patients with PBC. METHODS Frequency of hmAchR M3 autoantibodies was assessed by...

OBJECTIVE Investigate whether CXCR3 and its ligands were involved in the pathogenesis of primary biliary cirrhosis (PBC) in an autoimmune cholangitis animal model. METHODS Female C57BL/6 mice were injected with 5 mg/kg of poly I:C intraperitoneally twice a week for 24 weeks. PBC model was confirmed by liver function, serum autoantibodies and liver biopsy. Lymphocytes subsets in liver and sple...

A 73-year-old woman had previously been diagnosed with CREST syndrome, PBC and diabetes. Hepatic fibrosis was not evident, in spite of the transudative ascites and active esophageal varices. ACA were positive, whereas AMA and anti-gp210 antibodies were negative. She showed low urinary excretion of C-peptide and was weakly positive for anti-GAD antibody. She was diagnosed with a form of PBC that...
