Autism spectrum disorder (ASD) is a group of developmental pathologies that impair social communication and cause repetitive behaviors. The suggested roles noncoding RNAs in pathology led us to perform comparative analysis the microRNAs expressed serum human ASD patients. cohort 45 children with revealed six (miR-19a-3p, miR-361-5p, miR-3613-3p, miR-150-5p, miR-126-3p, miR-499a-5p) were at low very levels compared those healthy controls. A similar but less pronounced decrease was registered...

Abstract Purpose Traumatic Brain Injury (TBI) poses a significant global health burden, with Mild TBI (mTBI) being the most prevalent form. triggers activation of hypothalamic–pituitary–adrenal (HPA) axis, which in turn affects hypothalamic-pituitary–gonadal (HPG) axis regulating oogenesis and spermatogenesis. In this study, we investigated impact mTBI on sperm genome integrity using repetitive (r-mTBI) mouse model. Methods We assessed telomere length (TL), free TERRA (fTERRA), DNA/RNA...

Functional long non-coding RNAs (lncRNAs) have been in the limelight aging research because short telomeres are associated with higher levels of TERRA (Telomeric Repeat containing RNA). The genomic instability, which leads to telomeres, is a mechanism observed cell and class cancer cells. Psoriasis, skin disease, disorder epidermal keratinocytes, altered telomerase activity. Research on fraction nascent hybrid DNA offers avenues for new strategies. Skin blood samples from patients were...

Recently, we described the alteration of six miRNAs in serum autistic children, their fathers, mothers, siblings, and sperm mouse models. Studies model organisms suggest that noncoding RNAs participate transcriptional modulation pathways. Using mice, approaches to alter amount RNA fertilized eggs enable vivo intervention at an early stage development. Noncoding are very numerous spermatozoa. Our study addresses a fundamental question: can transfer content from result changes phenotypic...

Traumatic brain injury (TBI) is a major health problem affecting millions of people worldwide and leading to death or permanent damage. TBI affects the hypothalamic-pituitary-adrenal (HPA) axis either by primary hypothalamic-hypophyseal region secondary vascular damage, brain, and/or pituitary edema, vasospasm, inflammation. Neuroendocrine dysfunctions after have been clinically described in all hypothalamic-pituitary axes. We established mild (mTBI) rats using controlled cortical impact...

<b><i>Introduction:</i></b> Traumatic brain injuries (TBIs) pose a high risk of pituitary insufficiency development in patients. We have previously reported alterations miR-126-3p levels sera from patients with TBI-induced deficiency. <b><i>Methods:</i></b> To investigate why deficiency develops only some and to reveal the relationship between hormone axes, we used mice that were epigenetically modified at embryonic stage. These subjected mild...

Autism Spectrum Disorder (ASD) poses significant challenges to society and science due its impact on communication, social interaction, repetitive behavior patterns in affected children. The Developmental Disabilities Monitoring (ADDM) Network continuously monitors ASD prevalence characteristics. In 2020, was estimated at 1 36 children, with higher rates than previous estimates. This study focuses ongoing research conducted by Erciyes University. Serum samples from 45 patients 21 unrelated...

ABSTRACT Traumatic brain injury (TBI) causes inflammation, one of the main cellular aging. Telomere repeat-containing RNA (TERRA) hybridizes to telomere regions, forming R-loop structures and ensuring genome stabilization. Deregulation homeostasis leads genomic instability linked neurodegenerative diseases cancer. The hypothalamus-pituitary-adrenal (HPA) axis response is critical maintaining after TBI. We showed that local increase in transcription levels Crh Pomc genes, particular, suggests...

The WHO classifies t(6;9)-positive acute myeloid leukemia (AML) as a subgroup of high-risk AML because its clinical and biological peculiarities, such young age therapy resistance. t(6;9) encodes the DEK/NUP214 fusion oncoprotein that targets only small subpopulation bone marrow progenitors for leukemic transformation. This distinguishes from other oncoproteins, PML/RARα, RUNX1/ETO, or MLL/AF9, which have broad target population they block differentiation increase stem cell capacity. A...
