NCAPG, mediated through miR-378a-3p, adjusts cell proliferation, cellular never-ending cycle further advancement, as well as apoptosis regarding common squamous cellular carcinoma with the GSK-3β/β-catenin signaling.
Ovarian cancer (OC) ranks one of the most prevalent fatal tumors of female genital organs. Aberrant promoter methylation triggers changes of microRNA (miR)-375 in OC. Our study aimed to evaluate the mechanism of methylated miR-375 promoter region in OC cell malignancy and to seek the possible treatment for OC.

miR-375 promoter methylation level in OC tissues and cells was detected. miR-375 expression in OC tissues and cell lines was compared with that in demethylated cells. Role of miR-375 in OC progression was measured. Dual-luciferase reporter gene assay was utilized to verify the targeting relationship between miR-375 and Yes-associated protein 1 (YAP1). Then, Wnt/β-catenin pathway-related protein expression was tested. Moreover, xenograft transplantation was applied to confirm the
experiments.

Highly methylated miR-375 was seen in OC tissues and cell lines, while its expression was decreased as the promoter methylation increased. Demethylation in OC cells brought miR-375 back to normal level, with obviously declined cell invasion, migration and viability and improved apoptosis. Additionally, miR-375 targeted YAP1 to regulate the Wnt/β-catenin pathway protein expression. Overexpressed YAP1 reversed the protein expression, promoted cell invasion, migration and viability while reduced cell apoptosis. Overexpressed miR-375
inhibited OC progression.

Our study demonstrated that demethylated miR-375 inhibited OC growth by targeting YAP1 and downregulating the Wnt/β-catenin pathway. This investigation may offer novel insight for OC treatment.

The methylation status of RASSF1A, SOX17 and Wif-1 genes was evaluated in the cell free circulating DNA of 70 patients with advanced gastric cancer, using methylation-specific PCR. Patients with higher cell-free DNA concentration seem to have lower PFS, than patients with lower cell-free DNA concentration (p = 0.001). RASSF1A was the tumor suppressor gene, most frequently methylated in metastatic gastric cancer patients, followed by SOX17 and Wif-1 (74.3%, 60.0% and 47.1%, respectively). Patients having the SOX17 promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p less then 0.001). Patients having the Wif-1 promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p = 0.001). Patients having the RASSF1A promoter methylated, had lower progression free survival and overall survival, than unmethylated ones (p = 0.004). Promoter methylation of the examined genes was significantly associated with a decrease in progression free survival and overall survival, comparing to that of patients without methylation. Simultaneous methylation of the above genes was associated with even worse progression free survival and overall survival. The methylation of RASSF1A, SOX-17 and Wif-1 and genes, is a frequent epigenetic event in patients with advanced gastric cancer.Chicken anaemia virus (CAV) is a widespread pathogen that causes immunosuppression in chickens. The virus-induced immunosuppression often results in secondary infections and a sub-optimal response to vaccinations, leading to high mortality rates and significant economic losses in the poultry industry. The small circular ssDNA genome (2.3 kb) has three partially overlapping genes vp1, vp2 and vp3. VP1 capsid protein is highly variable and contains the neutralizing epitopes. Trichostatin A Here, we analysed CAV strains from Uruguay using the full-length vp1 gene and performed a global comparative analysis to provide new evidence about the origin, dispersion and genetic variability of the virus. The phylogenetic analysis classified CAV in three or four major clades. Two clades (II and III) grouped most of the strains circulating worldwide including the Uruguayan strains. The phylodynamic analyses indicated that CAV emerged in the early 1900s and diverged to originate clade II and III. This early period of viral emergence was characterised by local diversification promoted by the extremely high substitution rate inferred for the virus (3.8 × 10-4 substitutions/site/year). Later, the virus underwent a global spreading by intra- and inter-continental migrations that correlates with a significant rise in the effective population size. In South America, CAV was introduced in three different migratory events and spread across the continent. Our findings suggest that the current CAV distribution is the consequence of its continuous expansion capability that homogenizes the populations and prevents the detection of clear temporal and geographic patterns of evolution in most strains.RESEARCH HIGHLIGHTSCurrent strains of chicken anaemia virus emerged in Asia in the early 1900s.Chicken anaemia virus has a high substitution rate.The phylogenetic analysis classified chicken anaemia virus in four major clades.Evolution in South America was characterized by long migration and local spreading.We tested the filtration efficiency of Stryker T5 surgical helmets with and without the addition of a filter medium. Two particle counters were used to count the particles of sizes .5 μm, 1 μm, and 5 μm, both inside and outside the Stryker T5 helmet, concurrently. The total inward leakage (TIL) for the helmet with and without the filter was zero for 5 μm particles at all time points. The TIL (3.4) for the .5 μm particles decreased significantly after application of the filter (1.7; P = .007). We recommend that an N95 should be used inside the helmet system.Non-Hodgkin lymphoma (NHL) is a common haematological cancer that is comprised of approximately 30 subtypes, of which Waldenström Macroglobulinemia (WM) is a rare incurable form. It is typically managed using a watch-and-wait strategy that can contribute to illness uncertainty which may result in fear of cancer recurrence (FCR) and poor health-related quality of life (QOL). However, few studies have examined the correlates of FCR and QOL in NHL patients, including WM patients. One-hundred males and 92 females with a mean age of 62.7 years who were an average of 6.8 years from diagnosis completed the online questionnaire which asked about demographics, medical history, QOL, FCR, stress, anxiety and depression. Few NHL patients reported significant stress or affective distress, most had moderate-high QOL and 41% experienced recent FCR, relative to published cut-off scores. Poorer QOL was related to depression symptoms, FCR, higher illness burden (i.e. comorbidity) and fewer personal resources (i.e. unemployed), whereas FCR was related to shorter time since diagnosis and more depressive symptoms.
