Analysis of IL-17A, IL-17F, and miR-146a-5p Prior to Transplantation and Their Role in Kidney Transplant Recipients.

: The balance between regulatory and Th17 cells plays an important role in maintaining the immune tolerance after kidney transplantation (KTx) which is essential for transplantation success, defined as a long graft survival and an absence of organ rejection. The present study aimed to assess whether the pretransplant characteristics of IL-17A and IL-17F, their receptors, as well as miR-146a-5p, an miRNA associated with IL-17A/F regulation, can predict KTx outcomes. : A group of 108 pre-KTx dialysis patients and 125 healthy controls were investigated for single nucleotide substitutions within genes coding for , , their / receptors, and .

Relationship between Telomere Length, Genetic Variability and , , , Gene Co-Expression in the Clinicopathological Profile of Breast Cancer.

The molecular mechanisms of telomerase reverse transcriptase ( upregulation in breast cancer (BC) are complex. We compared genetic variability within and telomere length with the clinical data of patients with BC. Additionally, we assessed the expression of the , , and genes in BC patients and in BC organoids (3D cell cultures obtained from breast cancer tissues).

TERT genetic variability and telomere length as factors affecting survival and risk in acute myeloid leukaemia.

Acute myeloid leukaemia (AML) is a neoplasm of immature myeloid cells characterized by various cytogenetic alterations. The present study showed that in addition to the FLT3-ITD and NPM1 mutation status, telomere length (TL) and telomerase reverse transcriptase (TERT) gene polymorphisms may affect risk and overall survival (OS) in AML. TL was longer in healthy controls than in AML patients and positively correlated with age in the patients, but not in healthy subjects.

NF-κB1 -94del/del ATTG polymorphic variant maintains CLL at an early, mildest stage.

Background: NF-κB is an essential player in cancer biology, especially in tumor development, due to its constitutive activation, and because a four-base deletion (ATTG) in the NF-κB1 promoter region at site -94, alters mRNA stability and regulates translation efficiency. This polymorphism is a good candidate risk marker and modulator of clinical course in chronic lymphocytic leukemia (CLL). As the effect of this NF-κB1 gene polymorphism has not been studied in patients with CLL so far, the present study was undertaken to find out whether the NF-κB1 promoter -94 ins/del ATTG polymorphism might be an essential genetic risk factor and/or modulatory disease player associated with CLL.

Shared epitope and polymorphism of and encoding genes in Greek and Polish patients with rheumatoid arthritis.

The present study aimed to analyse and compare the distribution of MICA (rs1051792) and NKG2D/KLRK1 (rs1154831, rs1049174, rs2255336) polymorphisms in 61 Greek and 100 Polish patients with rheumatoid arthritis in relation to the presence of the HLA-DRB1 shared epitope and clinical parameters. Genotyping of selected polymorphism was performed using real-time PCR. HLA-DRB1 shared epitope alleles segregated differently in Greek and Polish patients but in both populations were detected in over 60% of cases.
