Background and objectives CKD is a global public health problem with significant mortality and morbidity.Design, setting, participants, & measurements We examined the multivariable association of plasma levels of IL-1, IL-1 receptor antagonist, IL-6, TNF-a, TGF-b, high-sensitivity C-reactive protein, fibrinogen, and serum albumin with progression of CKD in 3430 Chronic Renal Insufficiency Cohort study participants.Results Over a median follow-up time of 6.3 years, 899 participants reached the composite end point of $50% decline in eGFR from baseline or onset of ESRD. Elevated plasma levels of fibrinogen, IL-6, and TNF-a and lower serum albumin were associated with a greater decline in eGFR over time. After adjusting for demographics, BP, laboratory variables, medication use, and baseline eGFR, hazard ratios for the composite outcome were greater for the patients in the highest quartile of fibrinogen (hazard ratio, 2.05; 95% confidence interval, 1.64 to 2.55; P,0.001), IL-6 (hazard ratio, 1.44; 95% confidence interval, 1.17 to 1.77; P,0.01), and TNF-a (hazard ratio, 1.94; 95% confidence interval, 1.52 to 2.47; P,0.001) compared with those in the respective lowest quartiles. The hazard ratio was 3.48 (95% confidence interval, 2.88 to 4.21; P,0.001) for patients in the lowest serum albumin quartile relative to those in the highest quartile. When also adjusted for albuminuria, the associations of fibrinogen (hazard ratio, 1.49; 95% confidence interval, 1.20 to 1.86; P,0.001), serum albumin (hazard ratio, 1.52; 95% confidence interval, 1.24 to 1.87; P,0.001), and TNF-a (hazard ratio, 1.42; 95% confidence interval, 1.11 to 1.81; P,0.001) with outcome were attenuated but remained significant.Conclusions Elevated plasma levels of fibrinogen and TNF-a and decreased serum albumin are associated with rapid loss of kidney function in patients with CKD.

We conducted a joint (pooled) analysis of three genome-wide association studies (GWAS) 1-3 of esophageal squamous cell carcinoma (ESCC) in ethnic Chinese (5,337 ESCC cases and 5,787 controls) with 9,654 ESCC cases and 10,058 controls for follow-up. In a logistic regression model adjusted for age, sex, study, and two eigenvectors, two new loci achieved genome-wide significance, marked by rs7447927 at 5q31.2 (per-allele odds ratio (OR) = 0.85, 95% CI 0.82-0.88; P=7.72x10−20) and rs1642764 at 17p13.1 (per-allele OR= 0.88, 95% CI 0.85-0.91; P=3.10x10−13). rs7447927 is a synonymous single nucleotide polymorphism (SNP) in TMEM173 and rs1642764 is an intronic SNP in ATP1B2, near TP53. Furthermore, a locus in the HLA class II region at 6p21.32 (rs35597309) achieved genome-wide significance in the two populations at highest risk for ESSC (OR=1.33, 95% CI 1.22-1.46; P=1.99x10−10). Our joint analysis identified new ESCC susceptibility loci overall as well as a new locus unique to the ESCC high risk Taihang Mountain region.

The role of long noncoding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR) and its functional single nucleotide polymorphisms (SNPs) in papillary thyroid carcinoma (PTC) is still largely unclear. Therefore, we investigated the involvement of lncRNA HOTAIR and its three haplotype-tagging SNPs (htSNPs) in PTC. There was higher expression of HOTAIR in PTC tissues compared to normal tissues. A series of gain-loss assays demonstrated that HOTAIR acts as a PTC oncogene via promoting tumorigenic properties of PTC cells. Additionally, the functional HOTAIR rs920778 genetic variant was a PTC susceptibility SNP. Subjects with the HOTAIR rs920778 TT genotype had an odds ratio (OR) of 1.88, 1.25 and 1.61 (P = 6.0 × 10−6, P = 0.028 and P = 3.2 × 10−5) for developing PTC in Shandong, Jiangsu and Jilin case-control sets compared with subjects with the CC genotype. This statistically significant associations were only found between the rs920778 genetic polymorphism and PTC risk in females but not in males. The allele-specific regulation on HOTAIR expression by the rs920778 SNP was confirmed both in vitro and in vivo. Our results demonstrate that functional SNPs influencing lncRNA regulation may explain a part of PTC genetic basis.

Background T cell receptor-engineered T cells (TCR-Ts) therapy is a promising cancer treatment strategy. Nowadays, most studies focused on identification of high-avidity T cell receptors (TCRs) directed against neoantigens derived from somatic mutations. However, few neoantigens per patient could induce immune response in epithelial cancer and additionally many tumor-specific antigens could be derived from noncoding region. Autologous tumor cells (ATCs) could be unbiased stimulators in activating and enriching tumor-reactive T cells. However, it’s unknown if T cells engineered to express TCRs isolated from tumor-reactive T cells enriched by ATCs have strong antitumor response. Methods In this study, multiple TIL fragments obtained from a patient with esophageal squamous cell carcinoma (ESCC) were screened for specific recognition of ATCs. Tumor-reactive TILs were enriched by in vitro repeated stimulation of ATCs and isolated based on CD137 upregulation. Subsequently, tumor-reactive TCR was obtained by single-cell RT-PCR analysis and was introduced into peripheral blood lymphocytes to generate TCR-Ts. Results We found that phenotype and effect function of TIL fragments derived from different tumor sites were spatially heterogeneous. Of four TIL fragments, only TIL-F1 could specifically identify ATCs. Subsequently, we isolated CD8 + CD137 + T cells from pre- and post-stimulated TIL-F1 co-cultured with ATCs, and identified their most dominant TCR. This TCR was introduced into PBLs to generate TCR-Ts, which specifically identified and killed ATCs in vivo and in vitro. Conclusion This strategy provides the means to generate tumor-reactive TCR-Ts for ESCC, which is especially important for patients without prior knowledge of specific epitopes and might be applied for other cancers.
