Female patients contain much less TP53 mutations than male patients (65% vs. 24%, FDR = 0.01). Co-amplification of CDK4 and MDM2, CDK6 and EGFR were identified, which indicated cell cycle dysregulation and EGFR alteration are important co-occurring features in patients with METex 14 alteration. Of 9 tissue specimens having PD-L1 immunohistochemistry (IHC) results, 5 of them (55.5%) were found PD-L1 positive, which is comparable to other types of tumor. In 14 crizotinib-treated patients, the median progression free survival (mPFS) was 7 months. Upon resistance to crizotinib, two patients acquired secondary mutations in MET and one patient acquired BRAF p.K601E that can be a novel resistance mechanism. Conclusion Chinese cancer patients have a relatively lower frequency of METex14 alterations compared to Western patients. Patients with METex14 alterations showed distinct molecular characteristics and the representative case study showed responses to MET tyrosine kinase inhibitor (TKI).Ovarian cancer (OC) is the most lethal of gynecological tumors in women. Tumor metabolism has become a new opportunity in the treatment of tumors. Pyruvate dehydrogenase kinase 1 (PDK1), as a key regulatory enzyme implicated in metabolic reprogramming of tumors, abnormally high expressed in various tumors and involved in the regulation of tumor cell biological behavior. However, the role of PDK1 in the occurrence and development of ovarian cancer remains unclear. Our team identified the expression of PDK1 in ovarian cancer cell lines and tissues through RT-PCR and immunohistochemical staining and evaluated the correlation of PDK1 expression with clinicopathologic features of patients and survival analyses. We used a variety of in vitro experiments to explore the influence of PDK1 on proliferation, invasion, migration, colony formation, apoptosis and the cell cycle of ovarian cancer cell lines CAOV3 and SKOV3. PDK1 was highly expressed in ovarian cancer cell lines and OC tissues. High expression of PDK1 was closely correlated to tumor size, FIGO stage, extraovarian metastases status and distribution. Univariate and multivariate Cox regression analysis identified that PDK1 was an independent prognostic factor for overall survival. Moreover, PDK1 was a superior predictor in prognosis of ovarian cancer and the incorporation of CA125 into PDK1 generated a predictive combination that displayed better predictive accuracy for overall survival. Downregulation of PDK1 suppressed the biological behavior of ovarian cancer cells due to S phase arrest and cellular apoptosis. PDK1 may serve as a novel prognostic biomarker, even a promising antineoplastic target of ovarian cancer.Background Colorectal cancer (CRC) is one of the most common tumors, and its five-year survival is still very low despite of the advance of treatment strategies. The antitumor effect of ethanol extracted from radix of Actinidia chinensis (EERAC) were identified in human colon cancer cells, but the underlying mechanism remains unclear. Methods Cell proliferation, migration, and invasion were measured with cell counting kit-8 (CCK-8), wound healing, and transwell assays. Cell apoptosis and cycle were detected by flow cytometry. Western blotting and qRT-PCR were used to measure expression of target molecules. Xenograft tumor assay was applied to detect the influence of EERAC on tumor growth. Results we found that EERAC inhibited the cell viability, migration, and invasion of SW480 cells in a concentration dependent manner, but promoted apoptosis and the cell percentage in S phase significantly. The suppression of notch-signaling pathway molecules, Notch1, Jagged1, and c-Myc, by EERAC was confirmed using western blotting and immunohistochemical staining. The significant inhibition of tumor growth by EERAC was also observed. Meanwhile, EERAC remarkably reversed the effects of mastermind like transcriptional coactivator 1 (MAML1, activator of notch-signaling pathway) on cell survival of SW480. Conclusions EERAC might be a promising chemotherapeutic agent for CRC treatment.
Pathogenic inflammatory pathways are largely shared between different autoimmune and inflammatory diseases (AIDs). This offers the potential to develop a given targeted therapy in several AIDs.

We analyzed two clinical trials registries (ClinicalTrials.gov and EU Clinical Trials Register) to identify the targeted therapies whose development is shared between at least two of the most common AIDs [rheumatoid arthritis (RA), spondyloarthritis (SpA), cutaneous psoriasis (cPso), inflammatory bowel diseases (IBD), systemic lupus erythematosus (SLE), primary Sjögren's syndrome (pSS), systemic sclerosis (SSc), idiopathic inflammatory myopathies (IIM), giant cell arteritis (GCA), and multiple sclerosis (MS)] using an in-depth repurposing analysis.

We identified 142 shared targeted therapies. The four diseases in which shared targeted therapies were the most numerous were RA (
 = 92), cPso (
 = 67), IBD (
 = 58), and SLE (
 = 56). Pemetrexed The two clusters of diseases between which the overlap of targeted therapies waion of the current, clinically based classification of AIDs towards a more mechanistic-based taxonomy might be relevant.Osteoarthritis is a painful, disabling condition which is increasing in prevalence as a result of an ageing population. With no recognized disease-limiting therapeutics, arthroplasty of the hip and knee is the most common and effective treatment for lower limb osteoarthritis, however lower limb arthroplasty has a finite life-span and a proportion of patients will require revision arthroplasty. With increasing life expectancy and an increasing proportion of younger ( less then 65 years) patients undergoing arthroplasty, the demand for revision arthroplasty after implant failure is also set to increase. Statins are cholesterol-modulating drugs widely used for cardiovascular risk reduction which have been noted to have pleiotropic effects including potentially influencing arthroplasty survival. In vitro studies have demonstrated pleiotropic effects in human bone cells, including enhancement of osteoblastogenesis following simvastatin exposure, and in vivo studies have demonstrated that intraperitoneal simvastatin can increase peri-implant bone growth in rats following titanium tibial implant insertion.
