Piroplasmosis is a serious debilitating and sometimes fatal disease. Phylogenetic relationships within piroplasmida are complex and remain unclear. In the study, we assessed the relative resolution capabilities of the DNA sequences of the nuclear genes 40S ribosomal protein S5 (RPS5) and mitochondrial DNA Cytochrome c oxidase subunit III (cox3) gene in the phylogeny of Babesia and Theileria species isolates. We demonstrated that by using the cox3 gene can recover a better supported species tree for some Theileria species than when using the nuclear RPS5 gene alone, it tends to intra-specific diversity and considerable inter-specific difference. Additionally, the combined DNA sequences of the nuclear RPS5 and cox3 gene improved the inference of evolutionary relationships among Babesia and Theileria species. compound library chemical The mitochondrial cox3 gene outperforms nuclear RPS5 gene and yields better resolution on the intra-specific diversity of Babesia and Theileria species. However, the combined RPS5 nuclear DNA and cox3 DNA tree had more advantage in the phylogeny of Babesia and Theileria species than that of single gene alone. Histamine binds to one of the four G-protein-coupled receptors expressed by large cholangiocytes. Histamine specifically increases large cholangiocyte proliferation via H2 histamine receptor (H2HR), which is increased in patients with primary sclerosing cholangitis (PSC). Ranitidine decreases liver damage in Mdr2-/- (Abcb4 null) mice. We targeted hepatic H2HR in Mdr2-/- mice using Vivo-Morpholino. Wild-type and Mdr2-/- mice were treated with mismatch or H2HR Vivo-Morpholino by tail vein injection for one week. Liver damage, mast cell (MC) activation, biliary H2HR, and HA serum levels were studied. MC markers were determined by qPCR for chymase and c-kit in total liver. Biliary mass was detected by CK-19 along with F4/80 to evaluate inflammation (with semi-quantification). Biliary senescence was determined by immunofluorescence and SA-β-gal staining. Hepatic fibrosis was evaluated by staining for desmin, Sirius Red/Fast Green, and vimentin. Immunofluorescence for transforming growth factor-β1, vascular endothelial growth factor-A/C, cyclic AMP/extracellular signal-regulated kinase expression was performed. Transforming growth factor-β1 and vascular endothelial growth factor -A secretion was measured in serum and/or cholangiocyte supernatant. Treatment with H2HR Vivo-Morpholino in Mdr2-/-- mice decreased i) hepatic damage; ii) H2HR protein expression and MC presence/activation; iii) large intrahepatic bile duct mass/ inflammation and senescence; iv) fibrosis, angiogenesis, and cyclic AMP/phospho extracellular signal-regulated kinase expression. Inhibition of H2HR signaling ameliorates large ductal PSC-induced damage. The H2HR axis may be targeted in treating PSC. Dermal invasion is a hallmark of malignant melanoma. Thought the molecular alterations driving the progression of primary melanoma to metastatic disease have been studied extensively, the early progression of non-invasive primary melanoma to an invasive state is poorly understood. To elucidate the mechanisms underlying the transition from radial to vertical growth, the first step in melanoma invasion, we developed a zebrafish melanoma model in which constitutive activation of ribosomal protein S6 kinase A1 (Rps6ka1; RSK1) drives tumor invasion. Transcriptomic analysis of ribosomal protein S6 kinase A1-activated tumors identified metabolic changes, including up-regulation of genes associated with oxidative phosphorylation. Vertical growth phase human melanoma cells show higher oxygen consumption and preferential utilization of glutamine compared to radial growth phase melanoma cells. Peroxisome proliferator activated receptor gamma (PPARG) coactivator 1 alpha (PPARGC1A), also known as PPARG coactivator-1α (PGC1α), has been proposed as a master regulator of tumor oxidative phosphorylation. In human primary melanoma specimens, PGC1α protein expression was found to be positively associated with increased tumor thickness and expression of the proliferative marker Ki-67 and the reactive oxygen species scavenger scavenger receptor class A member 3 . PGC1α depletion modulated cellular processes associated with primary melanoma growth and invasion, including oxidative stress. These results support a role for PGC1α in mediating glutamine-driven oxidative phosphorylation to facilitate the invasive growth of primary melanoma. Repetitive transcranial magnetic stimulation (rTMS) is thought to modulate brain function through methods of electromagnetic induction. Over the last few decades, a large body of studies have investigated the clinical applications of rTMS in a variety of patient populations for a diverse range of symptoms from depressive symptomology to post-stroke motor functioning. There is still no clear consensus, however, on how rTMS influences cognitive functioning in the healthy brain. We conducted a quantitative meta-analysis in order to evaluate whether offline rTMS (the delivery of rTMS when not actively engaged in a cognitive task) influences cognition in healthy adults. More specifically, we examined studies that applied rTMS to the dorsal lateral prefrontal cortex (DLFPC) and that tracked cognitive outcomes both before and after a prescribed period of rTMS. Fifteen studies met our inclusion criteria. Cognitive performance was pooled and examined across studies for four cognitive domains (working memory, executive functioning, episodic memory, and visual perception) and under two types of stimulation conditions (excitatory and inhibitory rTMS). Whereas excitatory rTMS was associated with statistically reliable effects for improving executive functioning, inhibitory rTMS was associated with statistically reliable effects for improving episodic memory and visual perception. However, the magnitude of these effects was small and no other significant effects were observed. Though future studies are still needed, our findings suggest that offline forms of rTMS may have limited utility in affecting cognitive functioning when applied to the DLPFC in healthy adults, irrespective of cognitive domain or stimulation type.
