Loss of function of the CC2D1A gene appears to primarily affect the brain, leading to a range of behavioral problems in humans. In our study published in 2020, we found that the expressions of miR-19a-3p, miR-361-5p, miR-150-5p, miR-3613-3p, miR-126-3p and miR-499a-5p were downregulated in the serum samples of autistic patients, their families and mouse models (Cc2d1a +\/\u2212 and valproic acid treated males). Here, acquired non-Mendelian hereditary character in a genetically defined mouse model of autism (Cc2d1a +\/\u2212) correlates with the transcriptional alteration of five miRNAs. We seek to test the hypothesis that miRNA levels vary by changes in RNA\/DNA structure during development, thereby creating transcription alteration and cell memory. Behavioral tests were conducted on the offspring of Cc2d1a (+\/\u2212) mutant and control mice, such as novel object, social interaction, marble burying and tail suspension behavior. Two RNA fractions were isolated from mouse hippocampal tissues and sperm cells via standard TRIzol extraction: free RNA and the fraction of RNA bound to DNA in the form of a DNA\/RNA hybrid (R-loop). The expression levels of miR-19a-3p, miR-361-5p, miR-150-5p, miR-126-3p and miR-499a-5p were investigated by quantitative real-time RT-PCR. We report differences in the distribution of five miRNAs in the hippocampus between male and female mice, particularly in colonies of Cc2d1a (+\/\u2212) mice. Furthermore, the number of miRNAs engaged in the DNA\/RNA hybrid fraction is generally higher in the mutant pedigree than in the control group. On the other hand, in sperm, both fractions are at lower levels than in controls. R-loops contribute to the physiology and pathology of organisms including human disease. Here, we report a variation in five miRNA levels between gender and tissue. Our results suggest that the transcription levels of these five miRNAs are directly regulated by their RNA.<\/jats:p>","DOI":"10.3390\/biom14091183","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T07:38:57Z","timestamp":1726817937000},"page":"1183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Autism-Related Cc2d1a Heterozygous Mice: Increased Levels of miRNAs Retained in DNA\/RNA Hybrid Profiles (R-Loop)"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5644-5442","authenticated-orcid":false,"given":"Elif Funda","family":"Sener","sequence":"first","affiliation":[{"name":"Genome and Stem Cell Center (GENKOK), Erciyes University, 38039 Kayseri, T\u00fcrkiye"},{"name":"Department of Medical Biology, Medical Faculty, Erciyes University, 38039 Kayseri, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0829-8625","authenticated-orcid":false,"given":"Halime","family":"Dana","sequence":"additional","affiliation":[{"name":"Genome and Stem Cell Center (GENKOK), Erciyes University, 38039 Kayseri, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reyhan","family":"Tahtasakal","sequence":"additional","affiliation":[{"name":"Genome and Stem Cell Center (GENKOK), Erciyes University, 38039 Kayseri, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serpil","family":"Taheri","sequence":"additional","affiliation":[{"name":"Genome and Stem Cell Center (GENKOK), Erciyes University, 38039 Kayseri, T\u00fcrkiye"},{"name":"Department of Medical Biology, Medical Faculty, Erciyes University, 38039 Kayseri, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5522-0647","authenticated-orcid":false,"given":"Minoo","family":"Rassoulzadegan","sequence":"additional","affiliation":[{"name":"Genome and Stem Cell Center (GENKOK), Erciyes University, 38039 Kayseri, T\u00fcrkiye"},{"name":"The National Institute of Health and Medical Research (INSERM)-Centre National de la Recherche Scientifique (CNRS), Universit\u00e9 C\u00f4te d\u2019Azur, Inserm, 06000 Nice, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"607","DOI":"10.1007\/s10930-023-10146-0","article-title":"A Proteomics Investigation of Salivary Profiles as Potential Biomarkers for Autism Spectrum Disorder (ASD)","volume":"42","author":"Wormwood","year":"2023","journal-title":"Protein J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"244","DOI":"10.1016\/S1474-4422(22)00407-0","article-title":"Prediction of autism in infants: Progress and challenges","volume":"22","author":"Dawson","year":"2023","journal-title":"Lancet Neurol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"613","DOI":"10.1007\/s11011-016-9795-0","article-title":"The roles of CC2D1A and HTR1A gene expressions in autism spectrum disorders","volume":"31","author":"Sener","year":"2016","journal-title":"Metab.
