This study aims to evaluate the relationship between serum thymus and activation-regulated chemokine (TARC) levels with various clinicopathological conditions in patients with drug eruptions. The value of TARC in diagnosing drug-induced hypersensitivity syndrome (DIHS) was also examined.', 'Study participants included 84 patients who presented with generalized eruptions suspected to be drug-related, including DIHS, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), maculopapular exanthema (MPE), erythema multiforme (EM), erythroderma, and toxicoderma. The correlation coefficients between serum TARC levels and clinical parameters in peripheral blood samples were calculated.', 'Serum TARC levels in patients with DIHS were higher than those found in patients with SJS/TEN, MPE, EM, and toxicoderma. TARC levels had 100% sensitivity and 92.3% specificity in diagnosing DIHS, with a threshold value of 13,900\xa0pg/mL. Serum TARC levels positively correlated with age, white blood cell (WBC) count, neutrophil count, eosinophil count, monocyte count, atypical lymphocyte (Aty-ly) count, serum blood urea nitrogen (BUN) levels, and creatinine (Cr) levels. It negatively correlated with serum total protein (TP), albumin (Alb), and estimated glomerular filtration rate (eGFR). Among these clinical parameters, blood eosinophil counts were most strongly correlated with serum TARC levels, with a correlation coefficient of 0.53.

Hematopoiesis is regulated by proliferation, differentiation, and death. p16(INK4a) has been reported to regulate apoptosis and differentiation of diverse cells, as well as arresting the cell cycle at G1 phase. The aim of this study is to explore the properties of p16 in apoptosis and differentiation of erythroid cells.', 'We transfected the INK4a gene to K562 cells, which defect the INK4a gene, and compared the effect of enforced expression of p16(INK4a) with that of various additives, topoisomerase I inhibitor (SN 38), interferon-alpha, phosphatidyl-inositol-3 kinase inhibitor (LY294002), and serum deprivation, which arrest cell cycle at different phases. We also investigated the role of p16(INK4a) in normal day-6 human erythroid colony-forming cells by transfecting the INK4a gene.', 'p16(INK4a) induced cell cycle arrest at the G0/G1 phase, and promoted erythroid differentiation in viable K562 cells, but induced apoptosis in K562 cells with incomplete differentiation. The apoptosis induced by p16 was accompanied with downregulation of bcl-x and nuclear NF-kappaB. These findings were not observed in K562 cells treated with various additives. p16(INK4a) decreased the cell viability and promoted apoptosis in day-9 ECFC.

The current standard of care for glioblastoma (GBM) involves a combination of surgery, radiotherapy, and temozolomide chemotherapy, but this regimen fails to achieve long-term tumor control. Resistance to temozolomide is largely mediated by expression of the DNA repair enzyme MGMT; however, emerging evidence suggests that inactivation of MSH6 and other mismatch repair proteins plays an important role in temozolomide resistance. Here, we investigate endogenous MSH6 mutations in GBM, anaplastic oligodendroglial tumor tissue, and corresponding brain tumor-initiating cell lines (BTIC).', 'MSH6 sequence and MGMT promoter methylation were determined in human tumor samples and BTICs. Sensitivity to temozolomide was evaluated in vitro using BTICs in the absence and presence of O(6)-benzylguanine to deplete MGMT. The influence of MGMT and MSH6 status on in vivo sensitivity to temozolomide was evaluated using intracranial BTIC xenografts.', 'We identified 11 previously unreported mutations in MSH6 in nine different glioma samples and six paired BTIC lines from adult patients. In addition, MSH6 mutations were documented in three oligodendrogliomas and two treatment-naïve gliomas, both previously unreported findings. These mutations were found to influence the sensitivity of BTICs to temozolomide both in vitro and in vivo, independent of MGMT promoter methylation status.
