Abstract Many studies have illustrated the significance of long noncoding RNAs in oncogenesis and promotion of breast cancer (BC). However, the biological roles of CCDC183 antisense RNA 1 (CCDC183-AS1) in BC have rarely been characterized. Thus, we explored whether CCDC183-AS1 is involved in the malignancy of BC and elucidated the possible underlying mechanisms. Our data confirmed elevated CCDC183-AS1 expression in BC, which was associated with poor clinical outcomes. Functionally, knocking down CCDC183-AS1 hampered cell proliferation, colony formation, migration, and invasion in BC. Additionally, the absence of CCDC183-AS1 restrained tumor growth in vivo. Mechanistically, CCDC183-AS1 executed as a competitive endogenous RNA in… More >

Abstract piRNAs are novel members of small non-coding RNAs and have an impact on genetic and epigenetic mechanisms of cells. It was aimed to investigate the role of piR-651 on MCF-7 benign breast cancer cells by focusing on molecular characteristics. Anti-piR-651 was transfected and effects of piR-651 on proliferation, adhesion, and motility of MCF-7 cells were detected after the 24th, 48th, and 72nd hour. Gene expressions of piR-651, Ki-67, MMP-2, ERα, HIF-1α, and hTERT were determined by using RT-PCR. piR-651 inhibition caused the decrease of proliferation, adhesion (p < 0.001), and motility of MCF-7 cells. The efficiency of anti-piR-651 transfection supported… More >

Abstract This study aims to investigate the protective effects of peroxiredoxin 6 on the total motility and progressive motility of human spermatozoa. Semen samples with normal parameters were collected from 23 males and supplemented with different concentrations of peroxiredoxin 6. All the semen samples were measured according to the WHO 5th manual, and the motile spermatozoa were extracted using IVF fertilization medium supplemented with different peroxiredoxin 6 concentrations. Total motility and progressive motility were observed at different timepoints of culture at room temperature. After peroxiredoxin 6 supplementation, all groups had a significant increase in total motility and progressive motility compared to… More >

Abstract Sperm cryopreservation is useful in assisted reproductive technology and male fertility preservation. However, freezing and thawing significantly reduces the total and progressive motility of human spermatozoa. In the present study, we explored the effects of peroxiredoxin 6 (PRDX6) on total and progressive motility of human spermatozoa after cryopreservation. Semen samples of 20 males with normal parameters were collected and frozen in media supplemented with different concentrations of PRDX6 (0 mM, 10⁻⁵ mM, 10⁻⁷ mM, and 10⁻⁹ mM, respectively). Postthaw total and progressive motility of sperms were measured. The results showed that in comparison with 0 mM, the concentrations of 10⁻⁵… More >

Abstract Trypanosoma brucei is a protozoan flagellate that causes African sleeping sickness. Flagellar function in this organism is critical for life cycle progression and pathogenesis, however the regulation of flagellar motility is not well understood. The flagellar axoneme produces a complex beat through the precisely coordinated firing of many proteins, including multiple dynein motors. These motors are found in the inner arm and outer arm complexes. We are studying one of the inner arm dynein motors in the T. brucei flagellum: dynein-f. RNAi knockdown of genes for two components of dynein-f: DNAH10, the α heavy chain, and IC138, an intermediate chain,… More >

Abstract Our objective was to determine the effect of phosphodiesterase (PDE) inhibition on: 1) tyrosine phosphorylation of human spermatozoa at the tail level; and 2) sperm motion parameters and hyperactivated motility. The study was conducted with normozoospermic and asthenozoospermic samples incubated under in vitro capacitating conditions. The main outcome measures were computer-assisted sperm motion analysis and fluorescent immunodetection of phosphotyrosine-containing proteins. Pentoxifylline (PTX) was used as PDE inhibitor because of its wide use in the clinic. PTX-treatment significantly increased sperm velocity, hyperactivated motility and tyrosine-phosphorylation, both in normo and asthenozoospermic samples. Tyrosine-phosphorylation of tail proteins was highly conspicuous in both types… More >

Abstract Apigenin, a nonmutagenic flavonoid, has been shown to possess free radical scavenging activities, anticarcinogenic properties, antioxidant and anti-inflammatory effects. Recently, apigenin was reported to cause gastric relaxation in murine. To assess possible effects of apigenin on migration of bladder smooth muscle (SM) cell, we isolated SM cells from peri-cancer tissue of human bladder and established a cell model that was capable to overexpress transiently MEKK1 (MEK kinase 1). Results showed that overexpression of active human MEKK1 by adenoviruses infection induced migration of human bladder smooth muscle (hBSM) cells and phosphorylation of MAPKs, ERK, JNK and p38, which are the downstream… More >

Abstract Our objective was to study the incidence of sperm-tail phosphotyrosine immunoreactivity in normozoospermic and asthenozoospermic human sperm samples, its association with sperm motion parameters, particularly hyperactivated motility, and its potential involvement in the pathogenesis of asthenozoospermia. The work was conducted as a prospective experimental study in the Sperm Biology and Andrology laboratories of the Jones Institute, a medical school-based fertility center. The study subjects were healthy fertile male donors (normozoospermic samples) and infertile patients (asthenozoospermic samples) attending the center. Recently ejaculated semen samples were washed twice to eliminate seminal plasma and a swim-up was performed to select the motile population… More >

Abstract Dendritic cells (DCs) play a crucial role in initiating and amplifying both the innate and adaptive immune responses [1]. Clinically, the DCs-based immunotherapy against cancer is considered one of the most promising therapies to overcome cancers, but there are still many challenges need to be overcome [2]. The motility of DCs is especially crucial for migration of immature DCs into peripheral tissue and dynamic physical interaction between mature DCs and naive T cells in the secondary lymph node. This study focuses on the investigations of DCs at different differentiation stages and under various suppressive cytokines (VEGF, TGF-β1 and IL-10) conditioned… More >
