Identification of CSNK1D and KLK6 as two common upregulated genes present in BRCA1 mutated triple-negative breast cancer and ovarian epithelial carcinoma.

Deficiency in the breast cancer type 1 (BRCA1) gene expression predisposes to triple-negative breast cancer (TNBC) and ovarian cancer (OC). We previously identified by Comparative Genomic Hybridization (CGH) array a gain in the 17q25.3 genomic region in 90% of the BRCA1 mutated TNBC tissues, where 17 genes were up-regulated.

A Precision Medicine Approach Uncovers a Unique Signature of Neutrophils in Patients With Brushite Kidney Stones.

Introduction: We have previously found that papillary histopathology differs greatly between calcium oxalate and brushite stone formers (SF); the latter have much more papillary mineral deposition, tubular cell injury, and tissue fibrosis.

Methods: In this study, we applied unbiased orthogonal approaches on biopsied renal papillae and extracted stones from patients with brushite or calcium oxalate (CaOx) stones. Our goal was to discover stone type-specific molecular signatures to advance our understanding of the underlying pathogenesis.

Synthesis of Novel Fluorine Compounds Substituted-4-thiazolidinones Derived from Rhodanine Drug as Highly Bioactive Probes.

Aim And Objective: It is known that rhodanine drug has various biocidal activities. The aim of this work was to improve the structure of rhodanine drug via alkylation at N, S, and O- centers in addition to the introduction of fluorine atoms. The new fluorinated modified rhodanines 2-16 were evaluated as enzymatic probes for cellobiase activity produced by fungi and as CDK2 inhibitors of tumor cells.

Deep sequencing and analyses of miRNAs, isomiRs and miRNA induced silencing complex (miRISC)-associated miRNome in primary human chondrocytes.

MicroRNAs, a group of small, noncoding RNAs that post-transcriptionally regulate gene expression, play important roles in chondrocyte function and in the development of osteoarthritis. We characterized the dynamic repertoire of the chondrocyte miRNome and miRISC-associated miRNome by deep sequencing analysis of primary human chondrocytes. IL-1β treatment showed a modest effect on the expression profile of miRNAs in normal and osteoarthritis (OA) chondrocytes.

An effective and efficient method of transfecting primary human chondrocytes in suspension.

Human chondrocytes accumulate an ECM-rich matrix by secreting matrix macromolecules during monolayer culture, which makes them difficult to transfect efficiently. Here we report a non-viral based protocol to transfect the primary human chondrocytes with high efficiency in suspension. Chondrocyte cultures were digested using Pronase and Collagenase and transfected in suspension.

Histone Deacetylase Inhibitor Vorinostat (SAHA) Suppresses IL-1β-Induced Matrix Metallopeptidase-13 Expression by Inhibiting IL-6 in Osteoarthritis Chondrocyte.

Osteoarthritis (OA) is the most common whole-joint disease and is characterized by progressive loss of the cartilage matrix. Matrix metallopeptidase-13 (MMP-13) is a highly active and an abundantly expressed protease in OA cartilage and chondrocytes and degrades type II collagen and proteoglycans. We investigated the mechanism of MMP-13 suppression by histone deacetylase inhibitor vorinostat (SAHA).

Histone deacetylase inhibitor vorinostat (SAHA, MK0683) perturb miR-9-MCPIP1 axis to block IL-1β-induced IL-6 expression in human OA chondrocytes.

Aim Of The Study: High levels of IL-6 are believed to contribute to osteoarthritis (OA) pathogenesis. The expression of IL-6 is regulated post-transcriptionally by the miR-9-MCPIP-1 axis in chondrocytes. Vorinostat (SAHA) inhibits the IL-6 expression in OA chondrocytes.

miR-139 modulates MCPIP1/IL-6 expression and induces apoptosis in human OA chondrocytes.

IL-6 is an inflammatory cytokine and its overexpression plays an important role in osteoarthritis (OA) pathogenesis. Expression of IL-6 is regulated post-transcriptionally by MCPIP1. The 3' untranslated region (UTR) of MCPIP1 mRNA harbors a miR-139 'seed sequence', therefore we examined the post-transcriptional regulation of MCPIP1 by miR-139 and its impact on IL-6 expression in OA chondrocytes.

MicroRNA-9 promotion of interleukin-6 expression by inhibiting monocyte chemoattractant protein-induced protein 1 expression in interleukin-1β-stimulated human chondrocytes.

Objective: Enhanced expression of interleukin-6 (IL-6) plays an important role in the pathogenesis of osteoarthritis (OA). Monocyte chemoattractant protein-induced protein 1 (MCPIP-1) is a novel posttranscriptional regulator of IL-6 expression and is targeted by microRNA-9 (miR-9). We investigated the expression of MCPIP-1 in OA cartilage and explored whether targeting of MCPIP-1 by miR-9 contributes to enhanced IL-6 expression in OA.

MicroRNA-602 and microRNA-608 regulate sonic hedgehog expression via target sites in the coding region in human chondrocytes.

Objective: Hedgehog (HH) signaling has recently been associated with cartilage degradation in osteoarthritis (OA). Because interleukin-1β (IL-1β) has been implicated as a principal instigator of OA, we sought to determine whether IL-1β induces the expression of sonic HH (SHH) and its regulation by microRNAs (miRNAs) in human chondrocytes.

Methods: Expression of SHH protein in human OA cartilage and in an animal model of OA was determined by immunohistochemical analysis and immunofluorescence analysis, respectively.

Modulation of ten-eleven translocation 1 (TET1), Isocitrate Dehydrogenase (IDH) expression, α-Ketoglutarate (α-KG), and DNA hydroxymethylation levels by interleukin-1β in primary human chondrocytes.

5-Hydroxymethylcytosine (5-hmC) generated by ten-eleven translocation 1-3 (TET1-3) enzymes is an epigenetic mark present in many tissues with different degrees of abundance. IL-1β and TNF-α are the two major cytokines present in arthritic joints that modulate the expression of many genes associated with cartilage degradation in osteoarthritis. In the present study, we investigated the global 5-hmC content, the effects of IL-1β and TNF-α on 5-hmC content, and the expression and activity of TETs and isocitrate dehydrogenases in primary human chondrocytes.

Overexpression of β-catenin and cyclinD1 predicts a poor prognosis in ovarian serous carcinomas.

Unlabelled: Ovarian serous cancer is the most common subtype of epithelial ovarian cancer, and is the leading cause of death from gynecologic cancer. There is an important need for exploration of diagnostic and prognostic markers for this disease. β-catenin and cyclinD1 play central roles in the tumorigenesis for certain cancers.

Clinicopathological features of myxopapillary ependymoma.

Myxopapillary ependymoma (MPE) is a rare and distinct variant of ependymoma with a tendency for local recurrence and metastasis. Its clinicopathological spectrum is heterogenous, underscoring the need to understand and characterize MPE for better diagnosis and treatment. The purpose of this study was to explore the tumor biology and assess the management of patients with MPE.

Efficacy of recruitment maneuver for improving the brain dead marginal lungs to ideal.

Background: Because of the shortage of lungs for transplantation, finding the suitable lungs in brain-dead donors is an important issue. Recruitment maneuver is a strategy aimed at re-expanding collapsed and edematous lung tissue. The aim of this study was to assess the efficacy of this maneuver on improving marginal lungs for transplantation.

Osteolytic myxopapillary ependymoma with marked hyaline degeneration in a 72-year-old male: A case report.

Myxopapillary ependymomas (MPEs) are uncommon and account for ∼15% of all ependymomas. The current study presents a case of rare spinal MPE with abnormal hyaline degeneration. The patient was a 72-year-old male with a 10-month history of lower back pain.

Synthesis, physiochemical properties, photochemical probe, and antimicrobial effects of novel norfloxacin analogues.

The emerging resistance to antimicrobial drugs demands the synthesis of new remedies for microbial infections. Attempts have been made to prepare new compounds by modifications in the quinolone structure. An important method for the synthesis of new quinolone is using Vilsmeier approach but has its own limitations.

TSA downregulates Wilms tumor gene 1 (Wt1) expression at multiple levels.

The Wilms tumor gene WT1 encodes a zinc-finger transcription factor that is inactivated in a subset of pediatric kidney cancers. During embryogenesis, WT1 is expressed in a time- and tissue-specific manner in various organs including gonads and kidney but also in the hematopoietic system. Although widely regarded as a tumor suppressor gene, wild-type WT1 is overexpressed in a variety of hematologic malignancies, most notably in acute lymphoblastic leukemia as well as myelodysplastic syndromes.
