APC-targeted proinsulin expression inactivates insulin-specific memory CD8(+) T cells in NOD mice.

Type 1 diabetes (T1D) results from T-cell mediated autoimmune destruction of pancreatic β cells. Effector T-cell responses emerge early in disease development and expand as disease progresses. Following β cell destruction, a long-lived T-cell memory is generated that represents a barrier to islet transplantation and other cellular insulin-replacement therapies. Development of effective immunotherapies that control or ablate β cell destructive effector and memory T cell responses has the potential to prevent disease progression and recurrence. Targeting antigen expression to antigen-presenting cells inactivates cognate CD8(+) effector and memory T-cell responses and has therapeutic potential. Here we investigated this in the context of insulin-specific responses in the non-obese diabetic mouse where genetic immune tolerance defects could impact on therapeutic tolerance induction. Insulin-specific CD8(+) memory T cells transferred to mice expressing proinsulin in antigen-presenting cells proliferated in response to transgenically-expressed proinsulin and the majority were rapidly deleted. A small proportion of transferred insulin-specific Tmem remained undeleted and these were antigen-unresponsive, exhibited reduced TCR expression and H-2K(d)/insB15-23 tetramer binding and expressed co-inhibitory molecules. Expression of proinsulin in antigen-presenting cells also abolished the diabetogenic capacity of CD8(+) effector T cells. Therefore, destructive insulin-specific CD8(+) T cells are effectively inactivated by enforced proinsulin expression despite tolerance defects that exist in diabetes-prone NOD mice. These findings have important implications in developing immunotherapeutic approaches to T1D and other T cell-mediated autoimmune diseases.Immunology and Cell Biology accepted article preview online, 14 June 2017. doi:10.1038/icb.2017.48. - Source :PubMed

Shortage of dNTPs underlies altered replication dynamics and DNA breakage in the absence of the APC/C cofactor Cdh1.

The APC/C-Cdh1 ubiquitin-ligase complex targets cell cycle regulators for proteosomal degradation and helps prevent tumor development and accumulation of chromosomal aberrations. Replication stress has been proposed to be the main driver of genomic instability in the absence of Cdh1, but the real contribution of APC/C-Cdh1 to efficient replication, especially in normal cells, remains unclear. Here we show that, in primary MEFs, acute depletion or permanent ablation of Cdh1 slowed down replication fork movement and increased origin activity. Partial inhibition of origin firing does not accelerate replication forks, suggesting that fork progression is intrinsically limited in the absence of Cdh1. Moreover, exogenous supply of nucleotide precursors, or ectopic overexpression of RRM2, the regulatory subunit of Ribonucleotide Reductase, restore replication efficiency, indicating that dNTP availability could be impaired upon Cdh1 loss. Indeed, we found reduced dNTP levels in Cdh1-deficient MEFs. Importantly, DNA breakage is also significantly alleviated by increasing intracellular dNTP pools, strongly suggesting that genomic instability is the result of aberrant replication. These observations highlight the relevance of APC/C-Cdh1 activity during G1 to ensure an adequate supply of dNTPs to the replisome, prevent replication stress and the resulting chromosomal breaks and, ultimately, suppress tumorigenesis.Oncogene advance online publication, 12 June 2017; doi:10.1038/onc.2017.186. - Source :PubMed

Novel APC gene mutations associated with protein alteration in diffuse type gastric cancer.

The role of adenomatous polyposis coli (APC) gene in mitosis might be critical for regulation of genomic stability and chromosome segregation. APC gene mutations have been associated to have a role in colon cancer and since gastric and colon tumors share some common genetic lesions, it is relevant to investigate the role of APC tumor suppressor gene in gastric cancer. - Source :PubMed

Interplay Of Stereochemistry, Conformational Rigidity, And Ease Of Synthesis For 13-Membered Cyclic Peptidomimetics Containing APC Residues.

As part of a program to design small molecules that bind proteins, we require cyclic peptides (or peptidomimetics) that are severely constrained such that they adopt one predominant conformation in solution. This paper describes syntheses of the 13-membered cyclic tetrapeptides 1 containing aminopyrrolidine carboxyl (APC) residues. A linear precursor was prepared and used to determine optimal conditions for cyclization of that substrate. A special linker was prepared to enable cyclization of similar linear peptidomimetics on a solid phase, and the solution-phase cyclization conditions were shown to be appropriate for this too. Stereochemical variations were then used to determine the ideal APC configuration for cyclization of the linear precursors (on a solid phase, using the conditions identified previously). Consequently, a series of compounds were prepared that are representative of compounds 1. Conformational studies of representative compounds in DMSO solution were performed primarily using (i) NOE studies, (ii) quenched molecular dynamics simulations using no constraints from experiment, and (iii) MacroModel calculations with NMR constraints. All three strategies converged to the same conclusion: the backbone of molecules based on 1 tends to adopt one preferential conformation in solution and that conformation can be predicted from the stereochemistries of the α-amino acids involved. - Source :PubMed

The effect of EBV on WIF1, NLK, and APC gene methylation and expression in gastric carcinoma and nasopharyngeal cancer.

Epstein-Barr virus (EBV) is an important DNA tumor virus that is associated with approximately 10% of gastric carcinomas and 99% of nasopharyngeal cancers. DNA methylation and microRNAs (miRNAs) are the most studied epigenetic mechanisms that can prompt disease susceptibility. This study aimed to detect the effect of EBV on Wnt inhibitory factor 1 (WIF1), Nemo-like kinase (NLK), and adenomatous polyposis coli (APC) gene methylation and expression in gastric carcinoma and nasopharyngeal cancer. - Source :PubMed
