MicroRNAs (miRs) play important roles in initiation and progression of many pathologic processes. However, the roles of miRs in diabetic nephropathy remain unclear. This study was to determine whether miR-21 was involved in diabetic nephropathy and to explore the relationship between miR-21 and MMP9/TIMP1 expression in diabetic nephropathy. In situ(More)
Epithelial-to-mesenchymal transition (EMT) plays an important role in renal interstitial fibrosis (RIF) with diabetic nephropathy (DN). Smad7 (a inhibitory smad), a downstream signaling molecules of TGF-β1, represses the EMT. The physiological function of miR-21 is closely linked to EMT and RIF. However, it remained unclear whether miR-21 over-expression(More)
Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles. Here, the genome of the nematode-trapping fungus Arthrobotrys oligospora Fres. (ATCC24927) was reported. The genome contains 40.07 Mb(More)
Since the application of molecular methods, culture-independent methods (CIMs) have been developed to study microbial communities from various environments. In the past 20 years, several methods based on the direct amplification and analyses of the small subunit ribosomal RNA gene have been developed to directly study environmental microorganisms. These(More)
BACKGROUND The glycemic thresholds for diabetes diagnosis have long been at the forefront of discussion. However, no information about glycemic cutoff points has been made available for the Chinese population. The aim of the present study was to examine the association of fasting plasma glucose (FPG), 2-h plasma glucose (2-h PG) and HbA(1)c levels with(More)
Microbial ferulic acid decarboxylase (FADase) catalyzes the transformation of ferulic acid to 4-hydroxy-3-methoxystyrene (4-vinylguaiacol) via non-oxidative decarboxylation. Here we report the crystal structures of the Enterobacter sp. Px6-4 FADase and the enzyme in complex with substrate analogues. Our analyses revealed that FADase possessed a half-opened(More)
OBJECTIVE To determine the relationship between subclinical hypothyroidism (SCH) and the prevalence of diabetic retinopathy in type 2 diabetic patients. RESEARCH DESIGN AND METHODS A total of 1,170 type 2 diabetic patients were screened for thyroid function. There were 127 type 2 diabetic patients with SCH and 200 randomly selected euthyroid type 2(More)
Blocking the renin-angiotensin system (RAS) can reduce the risk of diabetes. Meanwhile, the angiotensin (Ang)-converting enzyme-2 (ACE2)/Ang-(1-7)/Mas axis has recently been proposed to function as a negative regulator of the RAS. In previous studies, we first demonstrated that ACE2 knockout (ACE2(-/)(y)) mice exhibit impaired glucose tolerance or diabetes.(More)
Microorganisms can attack and kill nematodes by diverse processes such as capturing, parasitizing, and producing toxins and enzymes. Extracellular enzymes, including serine proteases, chitinases, and collagenases are shown to be important virulence factors that can degrade the main chemical constituents of the nematode cuticle and eggshell. Here, we review(More)
OBJECTIVE To explore the association between epistasis among related genes of the renin-angiotensin system (RAS) and type 2 diabetes. RESEARCH DESIGN AND METHODS Gene polymorphisms were genotyped in 394 type 2 diabetic patients and 418 healthy control subjects in this case-control study. We used the multifactor dimensionality reduction method to identify(More)
