Alport syndrome (ATS) is a type-IV collagen inherited disorder, caused by mutations in COL4A3 and COL4A4 (autosomal recessive) or COL4A5 (X-linked). Clinical symptoms include progressive renal disease, eye abnormalities and high-tone sensorineural deafness. A renal histology very similar to ATS is observed in a subset of patients affected by mutations in MYH9, encoding non-muscle-myosin Type II...
We previously reported that podocyte-specific deletion of Myh9 (conventional myosin heavy chain 2A) in C57BL/6 mice does not cause spontaneous kidney disease but instead results in a predisposition to glomerulosclerosis in response to a second model of glomerular injury. In contrast, other investigators reported that podocyte-specific deletion of Myh9 (PodΔMyh9) resulted in spontaneous glomerul...
We investigated whether or not human disease-causing, amino acid substitutions in MYH9 could cause dominant phenotypes when introduced into the sole non-muscle myosin II heavy chain in Drosophila melanogaster (zip/MyoII). We characterized in vivo the effects of four MYH9-like mutations in the myosin rod-R1171C, D1430N, D1847K and R1939X-which occur at highly conserved residues. These engineered...
May-Hegglin anomaly (MHA) is a rare autosomal dominant disorder characterized by the triad of thrombocytopenia, giant platelets, and inclusion bodies in leukocytes. Recent evidence links MHA to mutations in the MYH9 gene. MHA has not been reported in Taiwan before. We report a 25-year-old Taiwanese man who presented with prolonged bleeding after dental extraction. Examination of peripheral bloo...
The Deleted in liver cancer 1 (Dlc1) gene codes for a Rho GTPase-activating protein that also acts as a tumour suppressor gene. Several studies have consistently found that overexpression leads to excessive cell elongation, cytoskeleton changes and subsequent cell death. However, none of these studies have been able to satisfactorily explain the Dlc1-induced cell morphological phenotypes and th...
• Myosin-II inhibition (with blebbistatin) and MYH9-RD mutations enhance shear fragmentation to pre/ proplatelet sizes. • Sustained shear activates normal myosin-II, which then favors division of pre/ proplatelets to smaller platelets. Megakaryocyte ploidy and the generation of pre/proplatelets are both increased in culture by pharmacologic inhibition of myosin-II, but nonmuscle myosin-IIA (MII...
Porcine reproductive and respiratory syndrome (PRRS) caused by the PRRS virus (PRRSV) is an important swine disease worldwide. PRRSV has a limited tropism for certain cells, which may at least in part be attributed to the expression of the necessary cellular molecules serving as the virus receptors or factors on host cells for virus binding or entry. However, these molecules conferring PRRSV in...
Mutations of MYH9, the gene for non-muscle myosin heavy chain IIA (NMMHC-IIA), cause a complex clinical phenotype characterized by macrothrombocytopenia and granulocyte inclusion bodies, often associated with deafness, cataracts and/or glomerulonephritis. The pathogenetic mechanisms of these defects are either completely unknown or controversial. In particular, it is a matter of debate whether ...
