The Lithuanian population has outstanding rates of alcohol consumption and alcohol related mortality. Alteration of brain dopaminergic system play a role in the risk for addiction disorders. We evaluated the association of one single nucleotide polymorphism rs1800497 in the Ankyrin Repeat and Kinase Domain Containing 1 - Dopamine Receptor D2 complex (ANKK1-DRD2) and a catechol-o-methyltransferase (COMT) rs4680 single nucleotide polymorphism with the risk for alcohol use disorder and impulsiveness in Lithuanian population. Both genetic polymorphisms are known to alter brain dopaminergic activity, thus we also investigated the possible interaction effect of these polymorphisms. ⋯ Our study demonstrated that the interaction of COMT rs4680 and ANKK1-DRD2 rs1800497 genetic polymorphisms is associated with a hazardous use of alcohol.

Cervical cancer (CC) is a common cancer threatens women's health worldwide. Circular RNAs (circRNAs) is critically involved in carcinogenesis of various cancers. This work aimed to explore the expression pattern, functions and mechanisms of hsa_circ_0001038 in CC. ⋯ Ectopic expression of hsa_circ_0001038 increased cell oncogenic properties. For mechanism investigation, hsa_circ_0001038 could sponge miR-337-3p to release its suppression on cyclin-M3 (CNNM3) and metastasis-associated in colon cancer 1 (MACC1), thereby promoting CC cell growth and invasive potential, respectively. In conclusion, hsa_circ_0001038 plays an oncogenic role in CC cells partly by activating CNNM3 and MACC1.

Identification the genetic factors in preeclampsia (PE) are useful to increase the current knowledge of the pathophysiology of the disorder. The genetic factors implicated for all cases of PE remain to be determined. This study was aimed to investigate association between ADD1 1378G > T, AGTR2 1675G > A, AGTR1 1166A > C, NOS3 894 G > T and CYP11B2 -344C > T gene polymorphisms in Iranian women with PE. ⋯ Our results showed a significant association between CYP11B2 -344C > T gene polymorphism with PE. This finding suggests that mentioned polymorphism may be associated with susceptibility to PE at least in IRAN.

Long noncoding RNAs (lncRNAs) have been shown to play an important role in tumor biogenesis and prognosis. The glioma is a grade classified cancer, however, we still lack the knowledge on their function during glioma progression. While previous studies have shown how lncRNAs regulate protein-coding gene epigenetically, it is still unclear how lncRNAs are regulated epigenetically. ⋯ Thirdly, we developed a DESeq2-GSEA-ceRNA-survival analysis strategy to investigate their functions. Particularly, MIR4435-2HG is highly expressed in high-grade glioma and may have an impact on EMT and TNFα signaling pathway by functioning as a miRNA sponge of miR-125a-5p and miR-125b-5p to increase the expression of CD44. Our results revealed the dynamic expression of lncRNAs in glioma progression and their epigenetic regulation mechanism.

Case Reports Meta Analysis
First identification of homozygous truncating CSRP3 variants in two unrelated cases with hypertrophic cardiomyopathy.
Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiovascular disease with an estimated prevalence of 1/500. More than 40 genes have been reported to cause HCM. Among them, CSRP3 is usually included on HCM gene panels used for molecular diagnosis by next-generation sequencing (NGS). ⋯ Meta-analysis of rare previously reported CSRP3 variants on HCM probands using ACMG guidelines indicate that only one variation (p. Cys58Gly) could be considered as likely pathogen. By combining meta-analysis results and identification of two unrelated HCM patients with homozygous CSRP3 truncating variants, we suggest that the association of CSRP3 as a validated HCM-causing gene require additional studies and those CSRP3 variants could result in HCM with an autosomal recessive inheritance rather than with an autosomal dominant transmission as usually reported on HCM (OMIM 612124).
