The aim of the present study is to investigate the effect of flavonoids from stem and leaf of Scutellaria baicalonsis Georgi (SSF) on multi-sites phosphorylation of tau protein in cerebral cortex and hippocampus of rats induced by okadaic acid (OA) and the regulative mechanism of the protein kinases.

The model of AD-like memory impairment and neuronal injuries was established in male SD rats who were microinjected with OA (200 ng/kg) to establish a memory impairment model and screened for successful model rats by Morris water maze on day 21 after surgery. The successful model rats were continuously administered with intragastric infusion (ig) SSF 25, 50, and 100 mg/kg or Ginkgo biloba leaves flavonoids (GLF) 200 mg/kg for 36 d. The relative protein expressed levels of phosphorylated tau protein at sites of Ser199, Ser202, Ser214, Ser404 and Thr231, protein kinases (CDK5, PKA, pTyr216-GSK3β and pSer9-GSK3β) were detected by Western blotting.

The relative protein expressed levels of p-tau(Ser199), p-tau(Sctivities of protein kinase CDK5, PKA, and GSK3β.

Buyang Huanwu Tang (BYHWT) and relevant Traditional Chinese medicine (TCM) has its unique advantages in the treatment of cerebral ischemia. However, its pharmacological mechanism have not been fully explained.

Base on the multi-component, also the entire disease network targets, the present study set out to identify major bioactive ingredients, key disease targets, and pathways of BYHWT against cerebral ischemia disease by systematic pharmacological methodology.

Both the bioactive compounds from the BYHWT and the positive drugs against cerebral ischemia were fully investigated. The binding targets of the positive drugs were then obtained. A virtual screening protocol was then used to highlight the compound-target interaction. And network was constructed to visual the compound-target binding effect after docking analysis. Moreover，the targets enrichment analysis for biological processes and pathways were revealed to further explore the function of bio-targets protein gene and its role in the signal pathway.

A total of 382 active ingredients of the BYHWT and 23 candidate disease targets were identified. Virtual screening results indicated that multiple bioactive compounds targeted multiple proteins. Each compounds act on one or more targets. The mechanisms were linked to 20 signaling pathways, and the key mechanism was related to serotonergic synapse, calcium signaling pathway and camp signaling pathways.

The present study explored the bioactive ingredients and mechanisms of BYHWT against cerebral ischemia by systematic pharmacological methodology. the novel methodology would provide a reference for the lead discovery of precursors, disease mechanism and material base for TCM.

Oesophgeal adenocarcinoma (OAC) is the most frequent cause of cancer death. POLO-like kinase 1 (PLK1) is overexpressed in broad spectrum of tumors and has prognostic value in many cancers including esophageal cancer, suggesting its potential as a therapeutic target. p53, the guardian of genome is the most important tumor suppressors that represses the promoter of PLK1, whereas tumor cells with inactive p53 are arrested in mitosis due to DNA damage. PLK1 expression has been linked to the elevated p53 expression and has been shown to act as a biomarker that predicts poor prognosis in OAC.

The aim of the present study was identification of PLK1 associated phosphorylation targets in p53 mutant and p53normal cells to explore the downstream signaliging evets.

Here we develop a proof-of-concept phospho-proteomics approach to identify possible biomarkers that can be used to identify mutant p53 or wild-type p53 pathways. We treated PLK1 asynchronously followed by mass spectrometry data analysis. Protein networking and motif analysis tools were used to identify the significant clusters and potential biomarkers.

We investigated approximately 1300 potential PLK1-dependent phosphopeptides by LC-MS/MS. In total, 2216 and 1155 high confidence phosphosites were identified in CP-A (p53+)and OE33 (p53-) cell lines owing to PLK1 inhibition. Further clustering and motif assessment uncovered many significant biomarkers with known and novel link to PLK1.

Taken together, our study suggests that PLK1 may serve as a potential therapeutic target in human OAC. The data highlight the efficacy and specificity of small molecule PLK1 kinase inhibitors to identify novel signaling pathways in vivo.

The origin of BBE is unknown, and some of its epidemiological, clinical, and radiographic features have not been fully characterized. The purpose of this study was to determine whether specific demographic characteristics are associated with BBE in cats; and whether BBE is associated with other relevant radiographic findings. BAY-1816032 purchase Pertinent data were collected from archived dental radiographs and electronic medical records of 97 client-owned cats. Results showed that BBE is common in cats presented for evaluation and treatment of dental disease; that breed, sex, and age are not associated with BBE; that BBE is not associated with a pattern of horizontal alveolar bone loss/extrusion or tooth resorption; that a pattern of vertical alveolar bone loss is a typical feature of BBE; and that BBE represents a common cause of canine tooth loss in cats.This short report describes the case discussion of 9-year-old patient with acute kidney injury due to paediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 with successful peritoneal dialysis via a peritoneal dialysis catheter inserted at the bedside in an intensive care setting.
