Mir-770-5p-Induced Cellular Switch To Sensitize Trastuzumab Resistant Breast Cancer Cells Targeting Her2/Egfr/Igf1r Bidirectional Crosstalk, Senem Noyan, Bala Gür Dedeoğlu
Turkish Journal of Biology
Background/aim: Studies highlighted the bidirectional crosstalk between the HER family members in breast cancer as resistance mechanism to anti-HER agents. Cross-signaling between HER2/EGFR and ER/IGF1R could play role in the development of resistance to therapeutics hence stimulating cell growth. To overcome this resistance, combined therapies targeting both pathways simultaneously have been proposed as an effective strategy. The involvement of miRNAs in resistance of targeted therapies like trastuzumab was demonstrated in recent studies. Hence the regulation of miRNAs in resistance state could reverse the cell behaviour to drugs. Previously we found that overexpression of miR-770-5p downregulated AKT and ERK expression through …

Turkish Journal of Medical Sciences
Background/aim: In this prospective study, we aimed to investigate the association of serum (s) and urine (u) IP-10, galectin-9, and SIGLEC-1 with disease activity in patients with systemic lupus erythematosus (SLE).Materials and methods: Sixty-three patients with active SLE (31 renal, 32 extrarenal) were included. Thirty patients with inactive SLE (15 renal, 15 extrarenal), 17 with renal active AAV, and 32 healthy volunteers were selected as control groups. Serum and urine IP-10, galectin-9, and SIGLEC-1 were tested using ELISA.Results: Levels of sIP-10 (p = 0.046), uIP-10 (p < 0.001), sGalectin-9 (p = 0.03), and uSIGLEC-1 (p = 0.006) were significantly higher in active SLE group compared to the inactive SLE; however, no differences were detected in the comparison of uGalectin-9 (p = 0.18) and sSIGLEC-1 (p = 0.69) between two groups. None of the biomarkers discriminated patients with active renal SLE from active extrarenal SLE. ROC analyses revealed an AUC of 0.63 (0.52–0.73) for sIP-10, 0.78 (0.68–0.86) for uIP-10, 0.64 (0.53–0.74) for sGalectin-9, and 0.68 (0.57–0.77) for uSIGLEC-1 in discriminating disease activity in SLE, which did not outperform C3 (0.75, 0.64–0.84) and C4 (0.72, 0.61–0.82). sIP-10 (p = 0.001), uIP-10 (p = 0.042), and uGalectin-9 (p = 0.009) were significantly increased in patients with active renal SLE compared to active renal AAV. sGalectin-9 (p < 0.001) and sIP-10 levels (p = 0.06) were decreased after 8 (5–22.5) months of treatment.Conclusion: sIP-10, uIP-10, sGalectin-9, and uSIGLEC-1 reflect global disease activity in SLE but do not outperform C3 and C4. sIP-10 and uIP-10 may be specific for active SLE compared to active AAV. sIP-10 and sGalectin-9 might be valuable in monitoring response after treatment.

Background/aim: Obesity is a chronic metabolic disease involving dysregulation of fat metabolism that affects 13% of the world’s population. Obesity has been linked to dyslipidemia with a lot of complication, including stroke, chronic kidney disease, fatty liver disease, and so on. One of the natural resources that have several potential effects including anticholesterol, antiobesity, and antidyslipidemia is the butterfly pea (Clitoria ternatea/CT). CT’s petal has been found to contain high levels of anthocyanins and tannins that can inhibit the biosynthesis of cholesterol and lipid. This study aims to investigate the antiobesity and antidyslipidemic effects of Clitoria ternatea extract (CTE).Materials and …
