Abstract Degraded water quality from nutrient pollution, physical, biological, and other chemical factors contributes to the development and persistence of many harmful algal blooms (HABs). The complex dynamics of the HABs is a challenge to marine ecosystems for the toxic effects reported. The consequences include fish, bird, and mammal mortality, respiratory or digestive tract problems, memory loss, seizures, lesions and skin irritation in many organisms. This review is intended to briefly summarize the recent reported information on harmful marine toxin deleterious effects over the primary organisms of the food web, namely algae, zooplankton and invertebrates.… More >

Abstract Tankyrase1 plays an essential role in cancer progression by regulating telomere length. The study aimed to determine expression of TNKS1 and its regulation in colorectal cancer (CRC) in 20 samples from Saudi patients. mRNA expression of TNKS1 in CRC and paired normal tissues was measured by qRT-PCR. Epigenetic modification of TNKS1 promoter was determined by methylation-specific PCR while somatic mutation was analyzed by Sanger sequencing in exon 10 of the gene. All cancerous and normal tissues expressed TNKS1, but level of expression in CRC tissues was significantly associated with tumor stage though no other parameters; age, gender,… More >

Abstract Histone deacetylation is a key modulator involved in cell proliferation, apoptosis, and mRNA transcription. However, the effects of histone deacetylation on C17.2 neural stem cells (NSCs) remain unclear. Here, the histone deacetylase inhibitors nicotinamide and trichostatin A (TSA) were used to determine the role of histone deacetylation on gene transcription in NSCs. The results showed that the mRNA expression of p53, Sox1, Sox2, and Bax were significantly higher in E14.5 NSCs than in C17.2 NSCs. Nestin, a marker gene of neuronal differentiation, did not differ significantly between E14.5 NSCs and C17.2 NSCs. The transcription levels More >

Abstract Fluoride is a key ingredient of many psychiatric drugs like fluoxetine (Prozac^®, Fluoxetine^®). Pregnant women frequently use this drug as they suffer from depression and anxiety disorders during this period. Fluoxetine is able to reach the fetus through the placenta and passes to the newborn through milk. In the present study, female Wistar rats were treated with 5, 10, and 20 mg/L fluoxetine (containing 94% fluorides) from pregnancy day 10 to day 20. After delivery, the levels of the enzymatic antioxidants in the brain of their offspring at postnatal day 2 were measured. The results More >

Abstract Cisplatin is a powerful anticancer drug but its nephrotoxic effects limit its clinical use. We aimed to evaluate the effect of mesenchymal stem cells (MSCs) injection or of captopril to counteract the cisplatin-induction of nephropathy. MSCs isolation, preparation and tracking, transforming growth factor-β (TGF-β) and interleukin-10 (IL-10) expressions, kidney function tests, oxidative stress state, and histological examinations were done. Cisplatininduced nephropathy was indicated biochemically and confirmed histopathologically. MSCs treatment showed normal kidney architecture, and significantly decreased oxidative stress and TGF-β while increased IL-10 and improved kidney function tests. Rats treated with cisplatin + captopril More >

Abstract The present research reports of quick and marked changes induced by plant extract of Euryops arabicus in the gene expression of 49-kDa apyrases, cytoskeletal proteins, ATPases, ADPase and amount of amino acid of pea (Pisum sativum L. var. Alaska). Pellets of cytoskeletals proteins (27000 xg) were probed with anti-apyrase antibody, biotinylated anti-rat, actin and alpha and beta-tubulin for Western blotting. ATPase and ADPase activities were determined based on the hydrolytic efficacy of adenine triphosphate and adenine diphosphate. By 72 hours, the abundance of apyrases, cytoskeletal proteins and amount of amino acid in pellets of 27000 xg… More >

Abstract Interleukin-22 (IL-22) is a member of IL-10 cytokine family which is expressed in activated T cells predominantly and in activated natural killer cells at lower levels. Previous studies have demonstrated the link between elevated levels of IL-22 and disease severity of psoriasis, Crohn’s disease, rheumatoid arthritis and interstitial lung diseases. However, the function of IL-22 in the development and progression of colorectal cancer (CRC) remains elusive. In this study, we first evaluated the IL-22/IL-22R1 level in CRC patients, and found that tumor tissues have more active expression of IL-22 and IL-22R1 than normal tissues,… More >

Abstract This study aimed to investigate the effect of hyaluronic acid (HA) on the expression of heat shock protein 70 (HSP70) in chondrocytes isolated from patients with osteoarthritis (OA) and Kashin-Beck disease (KBD). The chondrocytes were collected from OA and KBD patients, and chondrocytes isolated from patients of accident injuries were used as the control. The chondrocytes were treated with HA at different doses. HSP70 expression in chondrocytes at both mRNA and protein levels was tested by PCR and Western blot analysis. Compared with control, both mRNA and protein levels of HSP70 were higher in chondrocytes More >
