ARHGAP1, also known as RhoGAP, RhoGAP1, CDC42GAP and p50rhoGAP, is officially named Ras homology (Rho) GTPase-activating protein 1, which is one of the key members of RhoGAPs. Growing evidences demonstrate that several RhoGAPs are suppressed or downregulated in cancers. Thus, the aim of this study was to explore the effects of ARHGAP1 on cervical carcinoma cells. The human cervical carcinoma cells C-33A and SiHa were transduced with lentivirus targeting ARHGAP1 (lenti-ARHGAP1). Cellular proliferation, migration and invasion assays, as well as quantitative real-time polymerase chain reaction and Western blot assays, were performed in the control, negative control (infected with lentivirus) and ARHGAP1+-infected groups...

"Triatoma brasiliensis species complex" was defined as a monophyletic group of the species: T. brasiliensis, T. juazeirensis, T. melanica, and T. sherlocki. An alternative grouping scheme proposed the concept of "Brasiliensis subcomplex" which included the former species together with T. melanocephala, T. petrocchiae, T. lenti, T. tibiamaculata, and T. vitticeps. To evaluate the relationship among these taxa we combined the results obtained with four mitochondrial genes (12S, 16S, COI and Cytb, adding to 1,811bp) and geometric morphometric analysis of wings and heads...

PURPOSE: Posterior hyaloid removal during pars plana vitrectomy and lensectomy for ectopia lentis is commonly performed, but may increase the risk of intraoperative retinal breaks and postoperative retinal detachment. This study evaluated outcomes after pars plana vitrectomy and lensectomy with or without posterior hyaloid removal. METHODS: This retrospective observational cohort study included ectopia lentis cases that underwent pars plana vitrectomy and lensectomy (2005-2014), with or without intraoperative induction of a posterior vitreous detachment (PVD)...

Amyloid-β (Aβ) produces neurotoxicity in the brain and causes neuronal death, but the endogenous defense mechanism that is activated on Aβ insult is less well known. Here we found that acute Aβ increases the expression of PIAS1 and Mcl-1 via activation of MAPK/ERK, and Aβ induction of PIAS1 enhances HDAC1 SUMOylation in rat hippocampus. Knockdown of PIAS1 decreases endogenous HDAC1 SUMOylation and blocks Aβ induction of Mcl-1. Sumoylated HDAC1 reduces it association with CREB, increases CREB binding to the Mcl-1 promoter and mediates Aβ induction of Mcl-1 expression...

Colletotrichum lentis is a hemibiotrophic pathogen and causes anthracnose on lentil. To understand the molecular mechanism underlying the symptomatic phase of infection, a cDNA plasmid library was developed from the susceptible lentil cultivar Eston infected with an isolate of the virulent race 0 of C. lentis. The library was sequenced on the Sanger sequencing platform, generating a total of 11,094 expressed sequence tags (ESTs) representing 3,488 unigenes. Mapping of unigenes onto the C. lentis and the L. culinaris genomes resulted in the identification of 2,418 unigenes of fungal origin and 1,070 unigenes of plant origin...

Secreted metalloproteases have diverse roles in the formation, remodeling, and the destruction of extracellular matrix. Recessive mutations in the secreted metalloprotease ADAMTS17 cause ectopia lentis and short stature in humans with Weill-Marchesani-like syndrome and primary open angle glaucoma and ectopia lentis in dogs. Little is known about this protease or its connection to fibrillin microfibrils, whose major component, fibrillin-1, is genetically associated with ectopia lentis and alterations in height...

U16-binding protein 4 (ULBP4), a human ligand for natural killer group 2, member D (NKG2D) receptor on NK cells and subsets of T cells, is thought to activate anticancer immune responses. However, the expression pattern and prognostic effect of ULBP4 in nasopharyngeal carcinoma (NPC) has not been investigated. We first compared ULBP4 expression between archival 15 NPC tissues and 8 normal nasopharynx (NP) tissues using qPCR. Then ULBP4 expression among 111 NPC specimens was validated on immunohistochemical examination...

PurposeTo reveal the underlying genetic defect in two four-generation Chinese families with aniridia and explore the pathologic mechanism.MethodsFull ophthalmic examinations were performed in two families with aniridia. The PAX6 gene was directly sequenced in patients of two families, and the detected variants were screened in unaffected family members and two hundred unrelated healthy controls. Real-time quantitative PCR was used to explore pathologic mechanisms of the two variants.ResultsAniridia, cataract, and oscillatory nystagmus were observed in patients of the two families...

Purpose: The zonule of Zinn (ciliary zonule) is a system of fibers that centers the crystalline lens on the optical axis of the eye. Mutations in zonule components underlie syndromic conditions associated with a broad range of ocular pathologies, including microspherophakia and ectopia lentis. Here, we used HPLC-mass spectrometry to determine the molecular composition of the zonule. Methods: Tryptic digests of human and bovine zonular samples were analyzed by HPLC-mass spectrometry...

PURPOSE: To investigate the influence of lyophilization on the biological activity of recombinant lentiviral vectors of bone morphogenetic protein 2(BMP-2). METHODS: Recombinant lenti-BMP-2 was constructed. lenti-BMP-2 was transfected with rat bone marrow stromal cells (BMSCs) by multiplicity infection (MOI) of 10, 25, 50, 100, 200. The infection efficiency was observed by X-gal staining. Under suitable conditions, the lenti-BMP-2 and 10% trehalose ratio of lyophilized protective agent was mixed into the lyophilization form...

Achieving adherence to medications can be a serious challenge for patients affected by inflammatory bowel disease (IBD). Medical treatment is fundamental for inducing and maintaining remission, preventing flares and reducing the risk of colorectal cancer. Non-adherence may affect patients' quality of life resulting in unfavourable treatment outcomes, more hospitalizations and higher healthcare-related costs. Recognising and improving adherence is therefore a primary aim for the treatment of IBD. Areas covered: We critically discuss the current knowledge on medication non-adherence in adult patients affected by IBD, also mentioning a few issues concerning the paediatric and adolescent populations...

A rare case of bilateral ectopia lentis with isolated lens coloboma in Marfan syndrome is reported. A 21-year-old female presented with decreased vision in both eyes. Her unaided visual acuity was 20/200 and 20/400 in the right and left eye, respectively, improving to 20/40 with -4.5 DS/-3.0 DC x 10° correction in the right eye and 20/80 with -10.0 DS/-6.5 Dc x10° correction in the left eye. On slit lamp examination under mydriasis, both eyes revealed ectopia lentis with lens coloboma and stretched zonules...

OBJECTIVE: In clinical practice, patient characteristics predicting resistant hypertension (RH) include higher blood pressure levels, left ventricular hypertrophy, older age, obesity, chronic kidney disease and diabetes. On the contrary little is known about the role of serum uric acid (SUA) as a risk factor for RH in subjects from general population.

AIM: Emerging evidences indicate that heat shock protein 90 (HSP90) is associated with atherogenesis. However, the effect of HSP90 on plaque stability is largely unknown. In the present study, we explored the role of HSP90 in plaque development and its regulatory mechanisms on vasculature. METHODS: HSP90-overexpression lentivirus (Lenti-HSP90) was used to transfect apoE(-/-) mice after constrictive collars were planted at the right common carotid arteries. RESULTS: As a result, HSP90 gene overexpression led to reduction in en face plaque area, and increase in unstable plaque with heavier accumulation of lipids...
