Non-Coding RNAs as Key Regulators in Lung Cancer.

For several decades, most lung cancer investigations have focused on the search for mutations in candidate genes; however, in the last decade, due to the fact that most of the human genome is occupied by sequences that do not code for proteins, much attention has been paid to non-coding RNAs (ncRNAs) that perform regulatory functions. In this review, we principally focused on recent studies of the function, regulatory mechanisms, and therapeutic potential of ncRNAs including microRNA (miRNA), long ncRNA (lncRNA), and circular RNA (circRNA) in different types of lung cancer.

Single nucleotide polymorphism rs527236194 of the cytochrome B gene (MT-CYB) is associated with alterations in sperm parameters.

Background: The mitochondrial genome is substantially susceptible to mutations and has high polymorphism due to structural features, location, and lack of recombinant variability, as its inheritance is strictly maternal. All of these events can be accompanied by the accumulation of mitochondrial single nucleotide polymorphisms (mtSNPs) in the sperm. The aim of this research was to analyze the influence of mutations in the MT-CYB gene on sperm quality.

The level of secondary messengers and the redox state of NAD/NADH are associated with sperm quality in infertility.

In order to explore the interrelation of Calcium, cAMP, and redox state of pyridine nucleotides in seminal plasma and ejaculate quality in cases of idiopathic infertility we conducted an evaluation of 170 infertile males and 46 fertile males aged 20-43 years. Sperm analysis was undertaken according to WHO protocol. The content of Calcium in the seminal plasma was detected using optical emission spectrometry, cAMP levels were determined via enzymatic immunoassay.

In Vivo Antidepressant Efficacy of 3-Substituted Thietane-1,1-dioxide Derivative - A Preliminary Study for Novel Anti-Depression Therapy in Neurological Disorders.

Background: Psychosocial stress-induced depressive behavior is linked to the etiology of several neurological diseases viz., PTSD, and neurodegenerative disease like Alzheimer's Disease (AD). The repeated bouts of social stress defeat can be induced using Resident-Intruder- Paradigm (RIP) and Chronic Mild Social Stress (CMSS) animal models to assess the stress-induced depressive behavioral patterns.

MicroRNA-200 family expression analysis in metastatic clear cell renal cell carcinoma patients.

The aim of this study is to analyse the of expression levels of microRNA-200 family members in patients with metastatic clear cell renal cell carcinoma (ccRCC). Analysis of microRNA expression was performed on 23 paired DNA samples extracted from kidney tumour tissue and the surrounding normal renal parenchyma. MicroRna-200c was found to have significantly lower expression (in kidney tumour tissue compared to normal renal parenchyma.
