Wound healing is a complex process driven largely by the migration of a variety of distinct cell types from the wound margin into the wound zone. In this study, we identify the previously uncharacterized microtubule-severing enzyme, Fidgetin-like 2 (FL2), as a fundamental regulator of cell migration that can be targeted in vivo using(More)
Diabetic cardiomyopathy is responsible for substantial morbidity and mortality in the diabetic population. Increased oxidative stress has been associated with the pathogenesis of chronic diabetic complications including cardiomyopathy. Multiple biochemical mechanisms have been proposed to increase oxidative stress in diabetes. The present study was aimed at(More)
Fidgetin is a member of the AAA protein superfamily with important roles in mammalian development. Here we show that human Fidgetin is a potent microtubule severing and depolymerizing the enzyme used to regulate mitotic spindle architecture, dynamics and anaphase A. In vitro, recombinant human Fidgetin severs taxol-stabilized microtubules along their length(More)
BACKGROUND Endothelin-1 (ET-1) and sodium hydrogen exchanger-1 (NHE-1) are important mediators of several disease processes affecting the heart, especially relating to myocardial ischemia. There is evidence that their actions may be interrelated. Their contributions to diabetic heart disease have not been extensively documented. Accordingly, the aim of this(More)
Increased vascular permeability and blood flow alterations are characteristic features of diabetic retinal microangiopathy. The present study investigated vascular endothelial growth factor (VEGF) and its interactions with endothelin (ET) 1 and 3, endothelial, and inducible nitric oxide synthase (eNOS, iNOS) in mediating diabetes induced retinal vascular(More)
Human endothelial cells cultured under high glucose (HG) conditions were shown before to upregulate several basement membrane proteins, including fibronectin (FN), thus mimicking effects of diabetes. Using human macrovascular (HUVEC) and microvascular (HMEC) endothelial cell lines, we evaluated in the present study some of the key molecular signaling events(More)
The present study tried to determine the hearing threshold by brainstem evoked response audiometry (BERA) in the high-risk infants from a mediocre socio-economic background at around 1 year of age and correlate different risk factors with hearing loss. BERA was done on 127 infants of 6-18 months age of which 87 were high risk. All were given monaural(More)
INTRODUCTION Heme oxygenase (HO) isoforms, HO-1, and HO-2, are responsible for heme breakdown to iron and carbon monoxide (CO). HO may respond to oxidative stress and may modulate the expression of vasoactive factors like nitric oxide (NO). Since diabetes induced oxidative stress may change HO, the present study examined whether diabetes is associated with(More)
Endothelial cells (ECs) line the microvasculature and constitute a barrier between the vessel lumen and surrounding tissues. ECs inform circulating immune cells of the health and integrity of surrounding tissues, recruiting them in response to pathogens and tissue damage. ECs play an active role in the transmigration of immune cells across the vessel wall.(More)
