Cytokine Profile in Patients With Maturity-onset Diabetes of the Young (MODY).

BACKGROUND/AIM: High-sensitivity C-reactive protein (hs-CRP) is used in the differential diagnosis of maturity-onset diabetes of the young (MODY)-3, but other inflammatory markers have not been investigated in MODY patients. We aimed to compare the serum levels of anti-inflammatory and proinflammatory cytokines between MODY patients and healthy subjects and show the inflammatory features in MODY subtypes. PATIENTS AND METHODS: Thirty patients with clinically suspected MODY and 34 healthy controls were included in this study. Next-generation sequencing (NGS) was used for the molecular diagnosis of MODY subtypes. Serum levels of cytokines were measured using a multiplexed cytokine assay and hs-CRP concentration was determined by the immunoturbidimetric assay. RESULTS: The hs-CRP levels were higher in both NGS-confirmed (MODY, n=17) (p=0.009) and NGS-unconfirmed (non-MODY, n=13) patients (p<0.001) than those in controls. However, IL-1ß (p=0.001), IL-6 (p=0.018), IL-31 (p=0.003), TNF-α (p<0.001), and sCD40L (p=0.007) levels of MODY patients and IL-1ß (p=0.002), IL-31 (p<0.001), IL-22 (p=0.018), and sCD40L (p=0.039) levels of non-MODY patients were lower than those of controls. While hs-CRP levels were lower in MODY3 patients than non-MODY3 patients (p=0.009), IL-17A (p=0.006) and IL-23 (p=0.016) levels for the first time in this study were found to be higher in patients with MODY3 than in patients with other MODY subtypes (p<0.05). CONCLUSION: MODY patients had lower serum levels of the proinflammatory cytokines IL-1ß, IL-6, TNF-α, IL-31, and sCD40L compared to healthy controls. High IL-17A and IL-23 levels along with low hs-CRP levels may be potential markers to distinguish MODY3 from other MODY subtypes.

Kallikrein 11 Down-regulation in Breast Carcinoma: Correlation With Prognostic Parameters.

BACKGROUND: Expression of kallikrein-11 (KLK11) has been found to be related to the prognosis of various human cancer types but its physiological functions in the steps of breast cancer (BC) progression are still unknown. MATERIALS AND METHODS: BC and adjacent normal breast tissue samples were collected from 28 patients. KLK11 expression levels were determined by real-time polymerase chain reaction for each sample and associations with known prognostic features were statistically analyzed. RESULTS: Although there was slight up-regulation in tumor tissues overall, significant down-regulation of KLK11 expression in tumor tissue was observed in the elderly and in patients with perineural invasion. Furthermore, tumor size, grade, mitotic score, necrosis, calcification, lymphatic invasion, hormone receptor status and Ki67 expression were associated with altered KLK11 level. CONCLUSION: Changes in expression levels of KLK11, associated with patient characteristics, might be used as complementary data in order to predict clinical outcome and prognosis in BC.
