RESUMO
Background: Maternal and perinatal mortality is caused by a variety of factors, including preeclampsia. PE's onset and progression may be influenced by lncRNAs. The effect of long non-coding RNA (lncRNA) Colon cancer-associated transcription factor 1 (CCAT1) expression in the placenta of preeclampsia patients on preeclampsia progression was the focus of this investigation. Objectives: The aim of the current study is to check if the levels of expression of Colon cancer-associated transcription factor 1 (CCAT1) and Cyclin-dependent protein kinase 4 (CDK4) are associated with preeclampsia vulnerability and biogenesis. Subjects: and methods: This work included the participation of 160 people. Eighty of the patients had preeclampsia. The control group included 80 normal pregnant women. The two groups were almost of the same age. A thorough clinical examination was performed in all groups (including taking a detailed history, concentrating on parity, age and previous background of diabetes or hypertension). The expression levels of CCAT1 and CDK4 in placental tissue were determined using a real-time q PCR technique. Results: Expression levels of CCAT1 and CDK4 differed significantly between the study groups. preeclamptic patients having the highest level of CCAT1in comparison with control group, However, preeclamptic patients having lower level of CDK4 than controls. There was a strong negative association between CDK4 expression level and DBP, SBP, creatinine, urea and CCAT1 level of expression in the preeclamptic group, whereas there was a positive correlation between CCAT1 level of expression and DBP, SBP, urea and creatinine in patients group. Conclusion: Based on the findings of this study, it is possible that CCAT1 and CDK4 expression levels could be used to aid in the diagnosis and biogenesis of preeclampsia.
RESUMO
BACKGROUND: Psoriasis is a complex autoimmune multifactorial disease induced by interaction of environmental and genetic factors. This research aimed to clarify the association of NLRP3 (rs10754558) and PTPN22 (1858C/T) (rs2476601) polymorphisms with susceptibility to psoriasis. METHODS: This case-control study involved 150 patients diagnosed with psoriasis and 100 age- and gender-matched apparently healthy individuals. NLRP3 (rs10754558) polymorphism was done by real time PCR and PTPN22 1858C/T (rs2476601) genotype was identified by tetra-primer amplification refractory mutation system-polymerase chain reaction (PCR) method. RESULTS: The genotypes distribution of NLRP3 (rs10754558) were significantly associated with psoriasis (p<0.0001). Whereas for PTPN22 (1858C/T) (rs2476601), no significance was found (p=0.09). NLRP3 (rs10754558) GC genotype revealed a significant association with psoriasis (p<0.0001), mainly among male (p=0.004) patients with mild psoriasis (p=0.001) and affected extremities (p=0.0001). CONCLUSION: We can conclude that the NLRP3 (rs10754558) GC genotype may play a role in psoriasis susceptibility among male Egyptian populations with affected extremities. Future studies must evaluate its role in the prevention or the treatment of psoriasis.
