Project description:Evidence exists for late-life depression (LLD) as both a prodrome of and risk factor for Alzheimer?s disease (AD). The underlying neurobiological mechanisms are poorly understood. Impaired peripheral glucose metabolism may explain the association between depression and AD given the connection between type 2 diabetes mellitus with both depression and AD. Positron emission tomography (PET) measures of cerebral glucose metabolism are sensitive to detecting changes in neural circuitry in LLD and AD. Fasting serum glucose (FSG) in non-diabetic young (YC; n=20) and elderly controls (EC; n=12) and LLD patients (n=16) was correlated with PET scans of cerebral glucose metabolism on a voxel-wise basis. The negative correlations were more extensive in EC versus YC and in LLD patients versus EC. Increased FSG correlated with decreased cerebral glucose metabolism in LLD patients to a greater extent than in EC in heteromodal association cortices involved in mood symptoms and cognitive deficits observed in LLD and dementia. Negative correlations in YC were observed in sensory and motor regions. Understanding the neurobiological consequences of diabetes and associated conditions will have substantial public health significance given that this is a modifiable risk factor for which prevention strategies could have an important impact on lowering dementia risk.

Project description:Identification of differently methylated regions of CpG islands in epithelial ovarian cancer (EOC) tissue from patients with progression free survival <3 years (worse outcome) vs. patients with PFS >3 years (good outcome, relapse free until last follow up). Patients were homogenous in regard to clinical (FIGO III/IV, serous histology, optimally resected (macroscopically tumor free), platin-taxan chemotherapy) and molecular properties (immunohistochemistry for p16, BRCA1, Ki67 and p53)).

Project description:Tumors rely on multiple nutrients to meet cellular bioenergetics and macromolecular synthesis demands of rapidly dividing cells. Although the role of glucose and glutamine in cancer metabolism is well understood, the relative contribution of acetate metabolism remains to be clarified. We show that glutamine supplementation is not sufficient to prevent loss of cell viability in a subset of glucose-deprived melanoma cells, but synergizes with acetate to support cell survival. Glucose-deprived melanoma cells depend on both oxidative phosphorylation and acetate metabolism for cell survival. Acetate supplementation significantly contributed to maintenance of ATP levels in glucose-starved cells. Unlike acetate, short chain fatty acids such as butyrate and propionate failed to prevent loss of cell viability from glucose deprivation. In vivo studies revealed that in addition to nucleo-cytoplasmic acetate assimilating enzyme ACSS2, mitochondrial ACSS1 was critical for melanoma tumor growth in mice. Our data indicate that acetate metabolism may be a potential therapeutic target for BRAF mutant melanoma.

Project description:LINC00341 is a novel long intergenic non-protein coding RNA with unknown functions. In our report, we investigated LINC00341 expression and its prognostic value in cancer patients. DNA over-methylation triggered low expression of LINC00341 and that was associated with poor prognosis in cancers. A meta-analysis further confirmed that high expression of LINC00341 was associated with a better prognosis in cancer patients. Both gene set enrichment analysis and meta-analysis showed that LINC00341 inhibited cancer metastasis. Finally, a large-scale multicentre analysis supported a prognostic value of LINC00341 in cancers.

Project description:Objectivep53 gene, as "the guardian of the genome", is the most widely studied tumor suppressor gene. Previous studies have shown that about 50 percent of tumors have P53 dysfunction. This article aims to retrospectively analyze the correlation between p53 rs1625895 polymorphism and the prognosis of patients with diffuse large B-cell lymphoma (DLBCL).MethodsPCR combined with Sanger sequencing were used to detect rs1625895 genotype in 384 DLBCL patients. The relationship between rs1625895 polymorphisms and the clinical characteristics, first-line therapeutic effects and the prognosis of the patients were analyzed.ResultsAmong all the patients, 2 (0.5%) patients with AA genotype, 34 (8.9%) patients with AG genotype and 348 (90.6%) patients with GG genotype were identified. The patients with different rs1625895 genotypes did not have any difference in terms of age, gender, B symptoms (developing any of the following symptoms: unexplained recurrent fever (often above 38 °C), night sweats, and unexplained weight loss of 10% within 6 months ), erythrocyte sedimentation rate (ESR), international prognostic index (IPI) and molecular subtype (P>0.05). The overall response rate (ORR) was 82.9% and 82.8% in AA/AG and GG, respectively. There was no significant difference between the first-line therapeutic effects of the two groups (P>0.05). And there was also no difference between A allele carriers and homozygous G allele carriers for the 5-year progressionfree survival rate (PFS) (71.8% vs. 62.3%, χ2=1.351, P=0.245) and 5-year overall survival rate (OS) (72.2% vs. 64.1%, χ2=1.267, P=0.260). But in the subgroup with Germinal Center B-cell (GCB) type, the patients carrying A allele for rs1625895 had an obviously longer PFS (91.7% vs. 72.7%, χ2=4.493, P=0.034) and OS (91.7% vs. 76.7%, χ2=4.246, P=0.039) compared with the patients homozygous for the G allele. As for the patients with non-GCB subtype, there was no significant difference in PFS and OS between different rs1625895 genotypes (P>0.05). According to whether the first-line regimen contained rituximab or not, the patients were divided into two groups treated with cyclophosphoramide, doxorubicin, vincristine and prednisone (CHOP) or with rituximab and CHOP (R-CHOP). But in both subgroups, there was no significant difference in the 5-year PFS and OS between the AA/AG and GG patients, too (P>0.05).ConclusionFor DLBCL patients receiving CHOP regimen chemotherapy in the first line, p53 rs1625895 cannot predict the clinical efficacy and prognosis of the patients, but in the patients with GCB subtype, this polymorphism may be a prognostic indicator.
