Akebia trifoliata (Lardizabalaceae) is an important medicinal plant with multiple pharmacological effects. However, the lack of genomic information had limited the further excavation and utilization of this plant. An initial survey of the genome A. trifoliata was performed by next-generation sequencing, and then the genome size was inferred by flow cytometry. The whole genome survey of A. trifoliata generated 61.90 Gb of sequence data with approximately 95.51 × coverage. The genome size, heterozygosity and GC content obtained by k-mer analysis were almost 648.07 Mb, 0.72% and 36.11%, respectively. The genome size calculated by flow cytometry was 685.77 Mb, which was consistent with the results of genome survey. A total of 851,957 simple sequence repeats (SSR) were identified in the A. trifoliata genome. selleck kinase inhibitor Twenty-eight phenotypic traits and thirty pairs of SSR primers were selected for the analysis of the genetic diversity of 43 accessions of cultivated A. trifoliata. The results showed that 216 bands were generated by 30 pairs of SSR primers, of which 189 (87.5%) were polymorphic. In addition, the phenotypes and SSR markers were used for cluster analysis of 43 cultivated accessions. The results of the two clustering methods were partially consistent. The genome survey of A. trifoliata demonstrated that the genome size of this plant was about 648.07 Mb. In the present study, the size and characteristics of the genome of A. trifoliata were reported for the first time, which greatly enriched the genomic resources of A. trifoliata for the further research and utilization.Aptamers as potential alternatives for antibodies could be employed against hepatitis B surface antigen (HBsAg), the great hallmark and first serological marker in HBV, for further theragnostic applications. Therefore, isolation HBsAg specific aptamer was performed in this study with a modified Cell-SELEX method. HEK293T overexpressing HBsAg and HEK293T as target and control cells respectively, were incubated with single-stranded rounds of DNA library during six SELEX and Counter SELEX rounds. Here, we introduced the new modified Cell-SELEX using deoxyribonuclease I digestion to separate single stranded DNA aptamers against the HBsAg. Characterization and evaluation of selected sequences were performed using flow cytometry analysis. The results led to isolation of 15 different ssDNA clones in six rounds of selection which were categorized to four clusters based on common structural motifs. The evaluation of SELEX progress showed growth in aptamer affinity with increasing in the cycle number. Taken together, the application of modified cell-SELEX demonstrated the isolation of HBsAg-specific ssDNA aptamers with proper affinity. Modified cell-SELEX as an efficient method can shorten the selection procedure and increase the success rate while the benefits of cell-based SELEX will be retained. Selected aptamers could be applied in purification columns, diagnostic kits, and drug delivery system against HBV-related liver cancer.2,5-Dimethyl-celecoxib (DMC) is a close structural analog of the selective COX-2 inhibitor celecoxib that lacks COX-2-inhibitory function. Thus, DMC is a promising drug for anti-tumor. In this study, we evaluated the efficacy and the molecular basis of DMC in the treatment of human glioblastoma multiforme (GBM). DMC inhibited the growth and proliferation of GBM cell lines (LN229, A172, U251, and U87MG) in a dose-dependent manner (P  less then  0.001). In GBM cells treated with DMC, detection by flow cytometry showed cell cycle arrest, and proteins involved in cell cycle such as P21 were increased. Compared with control group, Annexin-V/PI-staining in DMC-treatment group was increased, indicating that DMC could induce apoptosis in GBM cells. Also, associated proteins including cleaved caspase 3 and cleaved PARP-1 were increased. It was further explored whether DMC blocked cell cycle and induced apoptosis in GBM cells through CIP2A/PP2A/AKT signaling pathway. After treatment of DMC, the phosphorylation of Akt was reduced while the total Akt level was not affected. DMC suppressed the expression of CIP2A in a time-dependent manner, while the CIP2A overexpression group reversed cell cycle and apoptotic protein expression led by DMC. Finally, in a xenograft model in nude mice using LN229 cells, DMC suppressed tumor growth. These findings proved that DMC could block cell cycle and induce apoptosis in GBM cells by suppressing CIP2A/PP2A/Akt signaling axis, which indicated that DMC could be an effective option for GBM treatment.ATP-sensitive potassium channels (KATP) couple vascular reactivity and metabolism with ischemic protection which makes them potential targets for prevention and management of ischemic stroke (IS). This study investigates the potential association between KATP polymorphisms and hypertension (HTN), dyslipidemia, and consequently ischemic stroke (IS). Nine hundred and fourteen (914) patients genotyped for KATP polymorphisms (rs2285676, rs1799858, rs4148671, rs61928479, and rs141294036) were analyzed. KATP rs141294036 (CC, adjusted OR = 1.59, 95%CI 1.17-2.14, P = 0.003) was related to higher HTN risk. Meanwhile, rs2285676 (AA + GA, adjusted OR = 1.53, 95%CI 1.08-2.19, P = 0.018) was associated with increased triglyceride level (≥ 1.7 mmol/L). rs2285676 (AA + GA, adjusted OR = 1.80, 95% CI 1.24-2.61, P = 0.002), rs1799858 (TT + CT, adjusted OR = 1.68, 95% CI 1.17-2.42, P = 0.005), and rs141294036 (TT + CT, adjusted OR = 1.90, 95% CI 1.30-2.78, P = 0.001) were related to increased low-density lipoprotein cholesterol (≥ 1.8 mmol/L). rs2285676 (AA + GA, adjusted OR = 2.57, 95% CI 1.74-3.82, P less then 0.001) and rs141294036 (TT + CT, adjusted OR = 1.93, 95% CI 1.27-2.93, P = 0.002) were related to increased apolipoprotein B (≥ 65 mg/dL). In addition, the 5 KATP polymorphisms were non-correlated with three types of dyslipidemia (total cholesterol, high-density lipoprotein cholesterol, and apolipoprotein AI). After median 50.6 month of follow-up, participants carrying CC genotype of rs141294036 showed correlation with elevated risk of new onset IS (adjusted HR = 2.55, 95% CI 1.23-5.27, P = 0.012). These novel findings suggest that KATP rs141294036 is associated with increased risk of HTN, dyslipidemia, and IS. Based on these correlations, KATP rs141294036 could be a promising target for early and personalized therapeutics as well as prevention strategies for the aforementioned clinical pathologies.
