This research aims to investigate the roles of SMYD2 and its interacted molecules in pancreatic adenocarcinoma (PAAD). Two PAAD-related gene expression datasets were downloaded to screen key molecules involved in tumor progression.

Network pharmacology-based prediction and experimental verification of the involvement of the PI3K/Akt pathway in the anti-thyroid cancer activity of crocin.

Crocin, a unique water-soluble carotenoid extracted from saffron, is known to exert anticancer activity against various cancer types, including thyroid cancer (TC). However, the detailed mechanism underlying the anticancer effect of crocin in TC needs further exploration. Targets of crocin and targets associated with TC were acquired from public databases.

Self-cascade catalytic single-atom nanozyme for enhanced breast cancer low-dose radiotherapy.

Radiotherapy (RT) efficacy can be promoted with the help of nanoenzyme that can "re-programing" the tumour's micro-environment by changing the expression level of special bio-molecules. However, problems such as low reaction efficiency, limited endogenous HO, and/or unsatisfactory results of a single catalysis mode in treatment limit the application in the RT field. Herein, a novel Au nanoparticles (AuNPs) decorated iron SAE (FeSAE@Au) was formulated for self-cascade catalytic RT.

Cyp2e1 knockdown attenuates high glucose-induced apoptosis and oxidative stress of cardiomyocytes by activating PI3K/Akt signaling.

Aims: Cyp2e1 is a crucial CYP450 enzyme participating in diabetes and cardiovascular disorder. However, the role of Cyp2e1 in diabetic cardiomyopathy (DCM) has never been reported. Thus, we intended to identify the effects of Cyp2e1 on cardiomyocytes under high glucose (HG) conditions.

Outcomes of adult patients with type 1 primary refractory acute myeloid leukemia: a single center experience.

Adult patients with newly diagnosed de novo acute myeloid leukemia (AML), who had less than a 50% reduction in blast numbers and with > 15% residual blasts after first cycle of induction chemotherapy, defined as type 1 primary refractory (REF1), have grave prognosis. We retrospectively analyzed the data of 58 patients with REF1 who received salvage treatments with curative intension to evaluate the impact of salvage regimens with regard to response and overall survival (OS). Seventeen patients received intermediate- or high-dose cytarabine (ID/HD Ara-C) based intensive salvage chemotherapy, 36 patients received G-CSF primed less intensive chemotherapy and 5 patients received novel targeted drugs based low intensive therapy.

Rationale and design of the optimal antithrombotic treatment for acute coronary syndrome patients with concomitant atrial fibrillation and implanted with new-generation drug-eluting stent: OPtimal management of anTIthroMbotic Agents (OPTIMA)-4 trial.

Background: About 5%-15% of acute coronary syndrome (ACS) patients undergoing stent implantation have concomitant atrial fibrillation and need both antiplatelet and anticoagulant therapies. The optimal antithrombotic regimen remains uncertain in this scenario.

Hypothesis: A multicenter randomized controlled trial (OPtimal management of anTIthroMbotic Agents [OPTIMA]-4) is designed to test the hypothesis that, for ACS patients with concomitant nonvalvular atrial fibrillation (NVAF) and having low-to-moderate risk of bleeding, clopidogrel is comparable in efficacy but superior in safety compared to ticagrelor while being used in combination with dabigatran after new-generation drug-eluting stent (DES) implantation.

Efficacy, feasibility and safety of TIPS in the treatment of recurrent portal hypertension with variceal bleeding after open splenectomy and esophagogastric devascularization.

Purpose: To investigate the efficacy, feasibility, and safety of transjugular intrahepatic portosystemic shunt (TIPS) as a treatment for patients with recurrent portal hypertension with variceal bleeding (RPHVB) who have previously undergone open splenectomy and esophagogastric devascularization (OSED).

Methods: The data were retrospectively retrieved from 39 cirrhotic RPHVB patients who had undergone OSED from August 2015 to December 2020. All patients were treated with TIPS using the Viabahn stent.

Cryptotanshinone Reverses Corticosteroid Insensitivity by Inhibition of Phosphoinositide-3-Kinase-δ in Chronic Obstructive Pulmonary Disease.

Purpose: Corticosteroid insensitivity has become a major barrier in the treatment of chronic obstructive pulmonary disease (COPD). It is known that oxidative stress reduces the expression and activity of histone deacetylase (HDAC)-2 by activating phosphoinositide-3-kinase-δ(PI3Kδ)/Akt pathway, which is a common mechanism. The aim of this study was to investigate whether cryptotanshinone (CPT) can improve corticosteroid sensitivity and to investigate the molecular mechanisms by which this occurs.

PRMT2 promotes RCC tumorigenesis and metastasis via enhancing WNT5A transcriptional expression.

Protein arginine methyltransferase 2 (PRMT2) is involved in several biological processes via histone methylation and transcriptional regulation. Although PRMT2 has been reported to affect breast cancer and glioblastoma progression, its role in renal cell cancer (RCC) remains unclear. Here, we found that PRMT2 was upregulated in primary RCC and RCC cell lines.

Kinesin family member 23 knockdown inhibits cell proliferation and epithelial-mesenchymal transition in esophageal carcinoma by inactivating the Wnt/β-catenin pathway.
