Familial hematuria (FH) is explained by at least four different genes (see below). About 50% of patients develop late proteinuria and chronic kidney disease (CKD). We hypothesized that MYH9/APOL1, two closely linked genes associated with CKD, may be associated with adverse progression in FH. Our study included 102 thin basement membrane nephropathy (TBMN) patients with three known COL4A3/COL4A4...
MYH9 disorders such as May-Hegglin anomaly are characterized by macrothrombocytopenia and cytoplasmic granulocyte inclusion bodies that result from mutations in MYH9, the gene for nonmuscle myosin heavy chain-IIA (NMMHC-IIA). We examined the expression of mutant NMMHC-IIA polypeptide in peripheral blood cells from patients with MYH9 5770delG and 5818delG mutations. A specific antibody to mutant...
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...
MicroRNAs (miRNAs) play important roles in regulating tumour development and progression. Here we show that miR-647 is repressed in gastric cancer (GC), and associated with GC metastasis. Moreover, we identify that miR-647 can suppress GC cell migration and invasion in vitro. Mechanistically, we confirm miR-647 directly binds to the 3' untranslated regions of SRF mRNA, and SRF binds to the CArG...

• 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...
The Arf-like protein Arl13b has been implicated in ciliogenesis and Sonic hedgehog signaling. Furthermore, we have previously shown that it regulates endocytic recycling traffic and interacts with actin. Herein, we report that the non-muscle myosin heavy chain IIA, also known as Myh9, is an Arl13b effector. Moreover, we found that both proteins localized to circular dorsal ruffles (CDRs) induce...
During proplatelet formation, a relatively homogeneous content of organelles is transported from the megakaryocyte (MK) to the nascent platelets along microtubule tracks. We found that platelets from Myh9(-/-) mice and a MYH9-RD patient were heterogeneous in their organelle content (granules and mitochondria). In addition, Myh9(-/-) MKs have an abnormal cytoplasmic clustering of organelles, sug...
