We suggest that ordered and random mapping protocols show different susceptibility to other design choices such as stimulus type and duration of the mapping cycle and can produce significantly different pRF results. TGFβ signaling pathway is critical for the cell division, differentiation and apoptosis, the aberrant regulation of which will result in severe diseases including cancer. N6-methyl-adenosine (m6A) is one of the most abundant modifications on mRNA, it is unclear yet how m6A epitranscriptome response to stimulation of TGFβ. Here, we found that cellular m6A level of RNA was elevated after TGFβ treatment, which might be regulated by upregulation of WTAP and METTL3. MeRIP-Seq of mRNAs of MCF7 with or without treated by TGFβ showed that mRNA with upregulated m6A modification level after TGFβ treatment were enriched in TGFβ signaling pathway. Phosphorylated level of SMAD2 or SMAD3 induced by TGFβ was impaired when WTAP was silenced. Moreover, the m6A modification and mRNA level of JunB, which is known as a cell cycle inhibitor, both were increased after induction of TGFβ and decreased after knockdown of WTAP. Intriguingly, growth inhibition caused by TGFβ was rescued in WTAP-knockdown cells. Collectively, these results reveal the key role that m6A pathway playing in the cell cycle arrest induced by TGFβ signaling, providing new mechanisms explanation for growth inhibition mediated by TGFβ. Studies have recently demonstrated that mesenchymal stem cells (MSCs) have therapeutic capabilities on many diseases and this effect is mainly mediated by miRNAs. However, the actual mechanism of MSCs paracrine effect on testis to improve male fertility is still elusive. Herein, we evaluated the altered expression of some spermatogenesis-related miRNAs and their target genes following transplantation of bone marrow (BM)-derived MSCs into testes of busulfan-induced azoospermic rats using real time PCR. Transplantation of MSCs improved fertility of azoospermic rats as revealed by enhanced serum levels of testosterone and estradiol, and upregulated expression of germ cell‑specific genes. Azo rats injected with MSCs also exhibited a significant downregulated expression of miRNA-19b, miRNA-100, miRNA-141, miRNA‑146a, miRNA-429, and let‑7a and a significant upregulated expression of miRNA-21, miRNA-34b, miRNA-34c, miRNA-122, miRNA-449a, miRNA-449b, and miRNA-449c in the testis as compared to Azo rats injected with phosphate buffer saline. Transplantation of MSCs was also accompanied with restoration of the disrupted expression of Ccnd1, E2F1, Myc, and PLCXD3 (target genes for miRNA-34 and miRNA‑449 clusters) and ERα and AKT1 (target genes for miRNA-100 and let‑7a) to level comparable to that of the fertile group. Upon these data, we infer that BM-MSCs can improve fertility of azoospermic rats and this effect was followed by altered expression of some spermatogenesis-related miRNAs and their target genes. These findings provide MSCs as a promising and effective cell-based therapeutic method for azoospermic patients, but further investigations are required before clinical application. Lipoxin A4 (LXA4) is considered a specialised pro-resolving mediator that decreases inflammation however, pro-inflammatory effects have been described in the airways. Here, we investigated whether LXA4 could influence airway hyperreactivity induced in mouse trachea by house dust mite extract (HDM) or TNFα. Intranasal instillation of HDM caused a serotonin (5-HT) mediated airway hyperreactivity ex vivo (Emax 78.1 ± 16.2% versus control 12.8 ± 1.0%) that was reduced by LXA4 installation one hour prior to HDM (Emax 49.9 ± 11.4%). Also, in isolated tracheal segments cultured for four days, HDM induced a hyperreactivity (Emax 33.2 ± 3.1% versus control 9.0 ± 0.7%) that was decreased by LXA4 (Emax 18.7 ± 1.5%). One part of the HDM-induced hyperreactivity could be inhibited by the TNFα-inhibitor etanercept. TNFα-induced upregulation of 5-HT responses (Emax 51.3 ± 1.2% versus control 13.9 ± 0.5%) was decreased by 10-1000 nM LXA4. In precontracted tracheal segments, LXA4 had no relaxing effect. PD123319 manufacturer Overall, LXA4 was able to decrease airway hyperreactivity induced by both HDM and TNFα, thus having a sub-acute anti-inflammatory effect in airway inflammation. A pulmonary infection model due to Scedosporium apiospermum in immunocompetent mice was developed. BALB/c mice were infected by endotracheal intubation with 5 × 106 conidia/mouse and disease progression was evaluated on days 1, 3, 5, 7, 11, 16, 21, 30, 50 and 60 post-infection through quantitative culture and histopathological analysis of lungs, livers, spleens, brains, and kidneys. There was no extrapulmonary dissemination during the study nor shown to be a lethal infection. The fungal burden in lungs was maintained from day 1-5 and gradually decreased by day 30 post-challenge. On day 60, 30% of mice showed complete elimination of the fungus. Severe alterations in the lung tissue were observed, as well as the presence of conidia and hyphae surrounded by a cellular infiltrate composed mainly of neutrophils in the first days of the infection. The elimination of fungal cells and normal tissue morphology were recovered throughout the study. Diabetic kidney disease is growing exponentially. This review aims to discuss alternate therapeutic approaches beyond the glomerulocentric view and to consider a novel tubulocentric approach with focus on the primary cilia. Renin-angiotensin-aldosterone system blockade to decrease glomerular capillary pressure and prevent albuminuria has been the mainstay of treatment for diabetic and non-diabetic proteinuric kidney disease. Landmark clinical trials have also shown cardiorenal benefit with sodium-glucose linked co-transporter 2 inhibitors and glucagon-like peptide 1 receptor analogues in patients with type 2 diabetes. Effective renoprotective drugs seem to have a common mechanistic mode of reducing glomerular hyperfiltration/hypertension. In the tubules, primary cilia act as "antennae" to detect mechanosensory changes such as glomerular hyperfiltration and trgger intracellular signalling pathways. They are also implicated in obesity and metabolic disorders linked to diabetes. To conclude, primary cilia of the kidney tubules offer a novel therapeutic target and may complement the current glomerulocentric approaches.
