We report on a 26-month-old boy with developmental delay and multiple congenital anomalies, including many features suggestive of either branchiootorenal syndrome (BOR) or oculoauriculovertebral spectrum (OAVS). Chromosomal microarray analysis (CMA) initially revealed a copy-number gain with a single BAC clone (RP11-79M1) mapping to 14q23.1. FISH analysis showed that the third copy of this geno...
The Hedgehog (Hh) signaling pathway is vital for vertebrate embryogenesis and aberrant activation of the pathway can cause tumorigenesis in humans. In this study, we used a phosphatome RNAi screen for regulators of Hh signaling to identify a member of the Eyes Absent protein family, Eya1, as a positive regulator of Hh signal transduction. Eya1 is both a phosphatase and transcriptional regulator...
OBJECTIVES Histone deacetylases (HDACs) plays important roles in the regulation of genes expression and contribute to the growth of cancer cells. The present study aimed to investigate the function of HDAC5 in human hepatocellular carcinoma (HCC). PATIENTS AND METHODS The expression of HDAC5 in human hepatocellular carcinoma tissues and cells was detected. MTT assay was used to measure the pr...
Jaw morphogenesis is a complex event mediated by inductive signals that establish and maintain the distinct developmental domains required for formation of hinged jaws, the defining feature of gnathostomes. The mandibular portion of pharyngeal arch 1 is patterned dorsally by Jagged-Notch signaling and ventrally by endothelin receptor A (EDNRA) signaling. Loss of EDNRA signaling disrupts normal ...
OBJECTIVES Successful further treatment of Wilms tumors (WTs) after preoperative chemotherapy and surgery depends on correct histopathologic risk stratification, including quantification of remaining blastemal elements. In the present study, we assessed the usefulness of protein markers for the detection of WT blastema. METHODS Expression of the candidate blastemal protein markers CITED1, SIX...
Quiescent muscle stem cells (MSCs) become activated in response to skeletal muscle injury to initiate regeneration. Activated MSCs proliferate and differentiate to repair damaged fibers or self-renew to maintain the pool and ensure future regeneration. The balance between self-renewal, proliferation, and differentiation is a tightly regulated process controlled by a genetic cascade involving de...
Congenital anomalies of the kidney and urinary tract (CAKUT) are among the most common developmental defects in humans. Despite of several known CAKUT-related loci (HNF1B, PAX2, EYA1, etc.), the genetic etiology of CAKUT remains to be elucidated for most patients. In this study, we report that disruption of the Holliday Junction resolvase gene Gen1 leads to renal agenesis, duplex kidney, hydron...
