Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection which is commonly known as COVID-19 (COronaVIrus Disease 2019) has creeped into the human population taking tolls of life and causing tremendous economic crisis. It is indeed crucial to gain knowledge about their characteristics and interactions with human host cells. It has been shown that the majority of our genome consists of non-coding RNAs. Non-coding RNAs including micro RNAs (miRNAs) and long non-coding RNAs (lncRNAs) display significant roles in regulating gene expression in almost all cancers and viral diseases. It is intriguing that miRNAs and lncRNAs remarkably regulate the function and expression of major immune components of SARS-CoV-2. MiRNAs act via RNA interference mechanism in which they bind to the complementary sequences of the viral RNA strand, inducing the formation of silencing complex that eventually degrades or inhibits the viral RNA and viral protein expression. LncRNAs have been extensively shown to regulate gene expression in cytokine storm and thus emerges as a critical target for COVID-19 treatment. These lncRNAs also act as competing endogenous RNAs (ceRNAs) by sponging miRNAs and thus affecting the expression of downstream targets during SARS-CoV-2 infection. In this review, we extensively discuss the role of miRNAs and lncRNAs, describe their mechanism of action and their different interacting human targets cells during SARS-CoV-2 infection. Finally, we discuss possible ways how an interference with their molecular function could be exploited for new therapies against SARS-CoV-2.

Abstract
Osteosarcoma (OS) is the most common primary malignant bone tumor which has unclear pathobiology. Hence, enlightening the exact molecular mechanism underlying osteosarcoma progression is crucial for developing new treatment strategies. One member of the ARID family of DNA binding proteins is ARID3A that is implicated in osteosarcoma pathogenesis. ARID3A could bind E2F1 and regulate the transcription of E2F1 targets. At the same time, BECN1 is a well-characterized autophagy regulator gene that is a direct target of E2F1. The present study aimed to investigate the effect of ARID3A on the expression of BECN1 in osteosarcoma cells. First, we determined gene expression levels of ARID3A, BECN1, and E2F1 in U-2 OS by qPCR and confirmed with online datasets from GEO database. In addition, the prognostic value of these genes was also evaluated from Kaplan-Meier plotter database. Next, ARID3A was overexpressed and silenced in order to investigate the effect of ARID3A on BECN1 expression and proliferation of U-2 OS cells. Our results demonstrated that BECN1 was negatively correlated with E2F1 and positively correlated with ARID3A based on initial expression and prognostic effect in OS. Overexpression of ARID3A upregulated BECN1 while silenced ARID3A downregulated BECN1 expression in U-2 OS cells. Additionally, silencing of ARID3A promoted colony formation and proliferation, whereas overexpression of ARID3A suppressed colony formation and proliferation of U-2 OS cells. Taken together, these results indicate that ARID3A could function as tumor suppressor and affect the expression level of BECN1 in U-2 OS cells.

Abstract
Growth factor indepdendent 1 (GFI1) is a SNAG-domain, DNA binding transcriptional repressor which controls myeloid differentiation through molecular mechanisms and co-factors that still remain to be clearly identified. Here we show that GFI1 associates with the chromodomain helicase DNA binding protein 4 (CHD4) and other components of the Nucleosome remodeling and deacetylase (NuRD) complex. In granulo-monocytic precursors, GFI1, CHD4 or GFI1/CHD4 complexes occupy sites enriched for histone marks associated with active transcription suggesting that GFI1 recruits the NuRD complex to target genes regulated by active or bivalent promoters and enhancers. GFI1 and GFI1/CHD4 complexes occupy promoters that are either enriched for IRF1 or SPI1 consensus binding sites, respectively. During neutrophil differentiation, chromatin closure and depletion of H3K4me2 occurs at different degrees depending on whether GFI1, CHD4 or both are present, indicating that GFI1 is more efficient in depleting of H3K4me2 and -me1 marks when associated with CHD4. Our data suggest that GFI1/CHD4 complexes regulate histone modifications differentially to enable regulation of target genes affecting immune response, nucleosome organization or cellular metabolic processes and that both the target gene specificity and the activity of GFI1 during myeloid differentiation depends on the presence of chromatin remodeling complexes. Helness et al. show that GFI1/CHD4 complexes critically regulate chromatin accessibility and histone modifications to regulate target genes affecting diverse cellular processes in neutrophils. Their results provide further insight into the molecular network operated by GFI1 for neutrophil differentiation programs.

Abstract
The human genome project revealed the existence of many thousands of long non-coding RNAs (lncRNAs). These transcripts that are over 200 nucleotides long were soon recognized for their importance in regulating gene expression. However, their poor conservation among species and their still controversial annotation has limited their study to some extent. Moreover, a generally lower expression of lncRNAs as compared to protein coding genes and their enigmatic biochemical mechanisms have impeded progress in the understanding of their biological roles. It is, however, known that lncRNAs engage in various kinds of interactions and can form complexes with other RNAs, with genomic DNA or proteins rendering their functional regulatory network quite complex. It has emerged from recent studies that lncRNAs exert important roles in gene expression that affect many cellular processes underlying development, cellular differentiation, but also the pathogenesis of blood cancers like leukemia and lymphoma. A number of lncRNAs have been found to be regulated by several well-known transcription factors including Myelocytomatosis viral oncogene homolog (MYC). The c-MYC gene is known to be one of the most frequently deregulated oncogenes and a driver for many human cancers. The c-MYC gene is very frequently activated by chromosomal translocations in hematopoietic cancers most prominently in B- or T-cell lymphoma or leukemia and much is already known about its role as a DNA binding transcriptional regulator. Although the understanding of MYC's regulatory role controlling lncRNA expression and how MYC itself is controlled by lncRNA in blood cancers is still at the beginning, an intriguing picture emerges indicating that c-MYC may execute part of its oncogenic function through lncRNAs. Several studies have identified lncRNAs regulating c-MYC expression and c-MYC regulated lncRNAs in different blood cancers and have unveiled new mechanisms how these RNA molecules act. In this review, we give an overview of lncRNAs that have been recognized as critical in the context of activated c-MYC in leukemia and lymphoma, describe their mechanism of action and their effect on transcriptional reprogramming in cancer cells. Finally, we discuss possible ways how an interference with their molecular function could be exploited for new cancer therapies.

Abstract
Long noncoding RNA (lncRNA) dysregulation is known to be taking part in majority of cancers, including osteosarcoma. In one of our previous studies, we showed that lncRNA MEG3 is being regulated by microRNA-664a (miR-664a) suppresses the migratory potential of osteosarcoma cells (U-2OS). We now report a novel lncRNA, namely, ERICD, which is linked to the transcription factor AT-rich interaction domain 3A (ARID3A) in U-2OS cells. We show that ARID3A binds to ERICD and indirectly interacts with each other via the E2F transcription factor 1 (E2F1). Furthermore, small interfering RNA (siRNA)-mediated knockdown of ERICD inhibited cell migration, formation of colonies, and proliferation in U-2OS cells. Overexpression of ARID3A inhibited cell migration, colony formation, and proliferation, whereas siRNA-mediated knockdown of ARID3A promoted cell migration, colony formation, and proliferation. Our findings indicate that ARID3A and lncRNA ERICD have plausible tumor suppressive and oncogenic functions, respectively, in osteosarcoma. Our data demonstrate the converse interaction between ARID3A and lncRNA ERICD that target DNA-binding proteins and dysregulation of their expression through E2F1 augments osteosarcoma progression. The cell rescue experiment also indicated E2F1 to be involved in the regulation of ARID3A and ERICD.

Abstract
Moringa oleifera (Moringaceae) is a plant known for having high antioxidant potency, anticancer, hepatoprotective, cardioprotective etc. and many more activities. Besides these, Moringaceae has the potential for attenuating the male sexual dysfunction. Reactive oxygen species/ROS were increased in cryptorchidism and therefore cause infertility by damaging sperm DNA and germ cell apoptosis. There was an increase in heat shock proteins (HSP) in cells, which is affected by heat shock. In the present study, the antioxidant effects of two different doses of M. oleifera Lam Extract (MOLE) on experimentally induced cryptorchid testes of rats was investigated. Forty two male rats (16 days old) were divided into four groups: a normal control group, a cryptorchidism-induced control group and two cryptorchidism-induced groups treated orally with either 400 or 800 mg/kg MOLE for 2 weeks. Our study showed that there were ruptures from interstitial spaces, separation of the germ cells from basal membrane, falling of the germ cells into the lumen, perivascular fibrosis, oedema, increased level of HSP70, apoptosis, malondialdehyde (MDA) and decrease in the level of superoxide dismutase (SOD) after the cryptorchidism. We found that pathological damages, oxidative stress, expression of the HSP70 and germ cell apoptosis were decreased in treated groups with MOLE. In brief, we can say that aqueous extract of M. oleifera reduces the oxidative stress in a unilateral cryptorchidism induced rats, and it might attenuate histopathological damages, HSP expression and germ cell apoptosis.

Abstract
A duplex real-time PCR assay with melting curve analysis, using the EvaGreen fluorescence dye, was developed for rapid and reliable identification of bovine and caprine in ruminant feeds. The method merges the use of bovine (Bos taurus) and caprine (Capra hircus) specific primers that amplify small fragments (bovine 96 bp and caprine 142 bp) of the mitochondrial 16S rRNA and 12S rRNA genes, respectively. DNA was isolated from heat-treated meats (133 °C/3 bar for 20 min) mixtures of bovine and caprine and was used to optimize the assay. Gene products of caprine and bovine produced two distinct melting peaks simultaneously at 82 and 86.8 °C, respectively. Duplex analysis of the reference samples showed that the detection limit of the assay was 0.003 % for bovine and 0.005 % for caprine species. The aim of this study was to develop a duplex real-time PCR assay followed by a melt curve step for sensitive, rapid, specific, and cost-effective detection of bovine and caprine species based on the amplicon melting peak in ruminant feeds to prevent Transmissible Spongiform Encephalopathies.

Abstract
UNLABELLED Colorectal cancer (CRC) is the most common cancer of the gastrointestinal tract. Different factors are responsible for the development of CRC. Transient Receptor Potential (TRP) which is an important component of calcium channel is associated with several pathological conditions like cancer, neurodegenerative and cardiovascular diseases. Thirty members of the family of TRP ion channel in mammals have been determined till now. The aim of this study is to investigate TRPM, TRPV and TRPC gene expression levels in tumor tissues of CRC patients and to analyze the relationship of expression in tumor tissue of CRC with other known prognostic factors. MATERIAL AND METHODS In this study, 93 CRC patients were included. The level of TRP gene expression in paraffin blocks of normal and cancerous colorectal tissue samples were studied at the level of mRNA with Real-time PCR. RESULTS The mRNA expression level of TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 genes in 37 female and 56 male patients diagnosed with CRC was revealed lower in tumor tissue as compared to normal tissue (p < 0.05). No statistically significant differences of mRNA expression levels of other TRP genes were found. CONCLUSIONS TRP gene family like TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 may be thought as potential genes contributing to tumorigenesis as their expression decreases in CRC as compared to normal tissues.

Abstract
A tetraplex PCR assay was developed for a rapid and reliable identification of horse, soybean, poultry, and pork species in sausages simultaneously. The method merges the use of horse (Equus caballus), soybean (Glycine max), poultry (Gallus gallus), and pork (Sus scrofa) specific primers that amplify small fragments (horse; 85bp, soybean; 100bp, poultry; 183bp and pork; 212bp) of the mitochondrial cyt b, lectin, 12S rRNA and ATPase subunit 6 genes respectively. Good quality DNA was isolated from reference sausage to optimize the assay. Tetraplex analysis of the reference sausage samples showed that the detection limit of the assay was 0.01% for each species. Taken together, all data indicated that this tetraplex PCR assay was a simple, rapid, sensitive, specific, and cost-effective detection method for horse, soybean, poultry, and pork species in commercial sausages.

Abstract
Caspases are important initiators and most well-known finishers of apoptosis. By changing the death propagation homeostatic equilibrium, their different expression patterns might trigger the progression of hazardous diseases like cancer. miR-221 is an oncogenic miRNA. It is known to have both anti-angiogenic and angiogenic effect. The aim of this work was to compare the expression levels of miR-221 and its target caspase-3 in different cancer cell lines and to find out a relationship between these two. We also tried to establish a prominent relationship between miR-221 and its role in apoptosis by studying their expression levels. Our results indicate that expression of caspase-3 is quite lower as compared to miR-221 expression in all of the selected cancer cell lines. As a result, we conclude that miR-221 may have a crucial role in repressing the expression of caspase-3 which may contribute to a lower apoptotic rate, thus supporting the selection of more aggressive cancer cells. To our knowledge, this is the first study related to the expression levels of caspase-3 and miR-221 in different cell lines at the same time. We expect that our study might pave the way for better understanding the role of miR-221 in apoptotic regulation of caspase-3.
