The role of sonic hedgehog signaling in the oropharyngeal epithelium during jaw development.

Sonic hedgehog (Shh) is expressed in the oropharyngeal epithelium, including the frontonasal ectodermal zone (FEZ), which is defined as the boundary between Shh and Fgf8 expression domains in the frontonasal epithelium. To investigate the role of SHH signaling from the oropharyngeal epithelium, we generated mice in which Shh expression is specifically deleted in the oropharyngeal epithelium (Isl1-Cre; Shh). In the mutant mouse, Shh expression was excised in the oropharyngeal epithelium as well as FEZ and ventral forebrain, consistent with the expression pattern of Isl1.

Podocyte Injury and Long-term Kidney Prognosis in Patients with Lupus Nephritis.

Background: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus. Like other types of glomerulonephritis, podocyte injury has been observed in patients with LN. However, the association between podocyte injury and kidney prognosis in patients with LN has not been well elucidated.

Sarcomere gene variants did not improve cardiac function in pediatric patients with dilated cardiomyopathy from Japanese cohorts.

Dilated cardiomyopathy (DCM) is a progressive myocardial disorder characterized by impaired cardiac contraction and ventricular dilation. However, some patients with DCM improve when experiencing left ventricular reverse remodeling (LVRR). Currently, the detailed association between genotypes and clinical outcomes, including LVRR, particularly among children, remains uncertain.

Retinoblastoma-binding Protein 9 Suppresses Intestinal Inflammation and Inflammation-induced Tumorigenesis in Mice.

Background & Aims: Retinoblastoma-binding protein 9 (RBBP9) was initially reported as cell cycle regulator via RB/E2F. Accumulating evidence has revealed the importance of RBBP9 in physiological and pathological states including inflammatory disease. However, the functional role of RBBP9 in ulcerative colitis (UC) and colitis-associated cancer (CAC) remains elusive.
