The interactions of drug semicarbazide hydrochloride in water and in aqueous-carbohydrate (D-xylose/L-arabinose) solutions from their physicochem. behavior are studied. D., ρ, ultrasonic speed, u and viscosity, η of the drug semicarbazide hydrochloride in water and in aqueous-D-xylose/L-arabinose (5 wt% and 10 wt% of D-xylose/L-arabinose in water, weight/weight) solvents were measured as functions of concentrations at temperatures, T = (293.15 – 318.15) K and at atm. pressure, p = 101 kPa. The measured data have been utilized to calculate various properties like the apparent molar volume, Vφ from d. measurements while apparent molar compressibility, Ks,ϕ, acoustic impedance, Z and intermol. free length, Lf from ultrasonic speed measurements. The values obtained from these parameters indicate strong solute-solvent interactions within the solutions The viscosity data have been analyzed using Jones-Dole equation and coefficients A and B were evaluated. The temperature derivative of B-coefficient, dB/dT together with activation parameters of viscous flow have also been determined The results are discussed in terms of hydrophilic-hydrophilic and hydrophilic-hydrophobic interactions in these systems along with the structure breaking/making ability of the drug.

Glioblastoma (GBM) is the most common primary brain cancer with the median age at diagnosis around 64 years, thus pointing to aging as an important risk factor. Indeed, aging, by increasing the senescence burden, is configured as a neg. prognostic factor for GBM stage. Furthermore, several anti-GBM therapies exist, such as temozolomide (TMZ) and etoposide (ETP), that unfortunately trigger senescence and the secretion of proinflammatory senescence-associated secretory phenotype (SASP) factors that are responsible for the improper burst of (i) tumorigenesis, (ii) cancer metastasis, (iii) immunosuppression, and (iv) tissue dysfunction. Thus, adjuvant therapies that limit senescence are urgently needed. The longevity-associated variant (LAV) of the bactericidal/permeability-increasing fold-containing family B member 4 (BPIFB4) gene previously demonstrated a modulatory activity in restoring age-related immune dysfunction and in balancing the low-grade inflammatory status of elderly people. Based on the above findings, we tested LAV-BPIFB4 senotherapeutic effects on senescent glioblastoma U87-MG cells and on T cells from GBM patients. We interrogated SA-β-gal and HLA-E senescence markers, SASP factors, and proliferation and apoptosis assays. The results highlighted a LAV-BPIFB4 remodeling of the senescent phenotype of GBM cells, enhancement of their sensitivity to temozolomide and a selective reduction of the T cells’ senescence from GBM patients. Overall, these findings candidate LAV-BPIFB4 as an adjuvant therapy for GBM.

The mechanism by which glioblastoma evades temozolomide (TMZ)-induced cytotoxicity is largely unknown. We hypothesized that mitochondria plays a role in this process. RNA transcriptomes were obtained from tumor samples and online databases. Expression of different proteins was manipulated using RNA interference or gene amplification. Autophagic activity and mitochondrial metabolism was assessed in vitro using the resp. cellular and mol. assays. In vivo anal. were also carried out in this study. High SH3GLB1 gene expression was found to be associated with higher disease grading and worse survival profiles. Single-cell transcriptome anal. of clin. samples suggested that SH3GLB1 and the altered gene levels of oxidative phosphorylation (OXPHOS) were related to subsets expressing a tumor-initiating cell signature. The SH3GLB1 protein was regulated by promoter binding with Sp1, a factor associated with TMZ resistance. Downregulation of SH3GLB1 resulted in retention of TMZ susceptibility, upregulated p62, and reduced LC3B-II. Autophagy inhibition by SH3GLB1 deficiency and chloroquine resulted in attenuated OXPHOS expression. Inhibition of SH3GLB1 in resistant cells resulted in alleviation of TMZ-enhanced mitochondrial metabolic function, such as mitochondrial membrane potential, mitochondrial respiration, and ATP production SH3GLB1 modulation could determine tumor susceptibility to TMZ. Finally, in animal models, resistant tumor cells with SH3GLB1 knockdown became resensitized to the anti-tumor effect of TMZ, including the suppression of TMZ-induced autophagy and OXPHOS. SH3GLB1 promotes TMZ resistance via autophagy to alter mitochondrial function. Characterizing SH3GLB1 in glioblastoma may help develop new therapeutic strategies against this disease in the future.

Zhou, Li; Huang, Xuming; Zhang, Yu; Wang, Jihui; Li, Haiyan; Huang, Haiwei published the artcile< PSMG3-AS1 enhances glioma resistance to temozolomide via stabilizing c-Myc in the nucleus.>, HPLC of Formula: 112-63-0, the main research area is PSMG3-AS1; c-Myc; chemotherapy resistance; long non-coding RNA (LncRNA); temozolomide.

Glioblastoma (GBM) is the main form of primary brain malignancies with a dismal prognosis partly due to its invasive growth and rapid relapse. GBM frequently developed resistance to current standard-of-care therapeutic modalities, including surgery, radiation and chemotherapy, of which temozolomide (TMZ) is the most widely used first-line anti-GBM drug. Despite the intense efforts of the past decades, the underlying mechanisms of GBM resistance to TMZ remain largely unclear. Here we show that the long noncoding RNA (lncRNA) PSMG3-AS1 is significantly upregulated in GBM and its expression correlates with the grade of glioma, with the highest level observed in GBM (Grade IV glioma). We also demonstrated that PSMG3-AS1 mediates the resistance of GBM to TMZ, as knockdown of PSMG3-AS1 remarkably increased the sensitivity whereas overexpression of PSMG3-AS1 in sensitive GBM cell line induced a resistance phenotype to TMZ. Mechanistically, PSMG3-AS1 directly binds to c-Myc and thus stabilizes c-Myc in the nucleus to promote the survival of GBM cells under treatment of TMZ. Our data demonstrated an unreported role of PSMG3-AS1 in TMZ resistance and provide a potential novel target to tackle TMZ resistance in GBM.

Han, Fengfeng; Jin, Qi; Xiao, Junpeng; Wu, Lili; Zhang, Xitian published the artcile< V2CTX catalyzes polysulfide conversion to enhance the redox kinetics of Li-S batteries>, Application of C19H34O2, the main research area is vanadium carbide polysulfide conversion redox kinetics lithium sulfur battery.

Lithium-sulfur (Li-S) batteries have the potential to become the future energy storage system, yet they are plagued by sluggish redox kinetics. Therefore, enhancing the redox kinetics of polysulfides is key for the development of high-energy d. and long-life Li-S batteries. Herein, a Ketjen Black (KB)/V2CTX modified separator (KB/V2CTX-PP) based on the catalytic effect in continuous solid-to-liquid-to-solid reactions is proposed to accelerate the conversion of sulfur species during the charge/discharge process in which the V2CTX can enhance the redox kinetics and inhibit polysulfide shuttling. The cells assembled with KB/V2CTX-PP achieve a gratifying first discharge capacity of 1236.1 mA h g-1 at 0.2C and the average capacity decay per cycle reaches 0.049% within 1000 cycles at 1C. The work provides an efficient idea to accelerate redox conversion and suppress shuttle effects by designing a multifunctional catalytic separator.
