Abstract
High-throughput ribosome profiling demonstrates the translation of thousands of small open reading frames located in the 5' untranslated regions of messenger RNAs (upstream ORFs). Upstream ORF can both perform a regulatory function by influencing the translation of the downstream main ORF and encode a small functional protein or microprotein. In this work, we showed that the 5' untranslated region of the PRPF19 mRNA encodes an upstream ORF that is translated in human cells. Inactivation of this upstream ORF reduces the viability of human cells.

Abstract
Mitochondrial ribosome assembly is a complex multi-step process involving many additional factors. Ribosome formation differs in various groups of organisms. However, there are universal steps of assembly and conservative factors that have been retained in evolutionarily distant taxa. METTL17, the object of the current study, is one of these conservative factors involved in mitochondrial ribosome assembly. It is present in both bacteria and the mitochondria of eukaryotes, in particular mice and humans. In this study, we tested a hypothesis of putative METTL17 methyltransferase activity. MALDI-TOF mass spectrometry was used to evaluate the methylation of a putative METTL17 target - a 12S rRNA region interacting with METTL17 during mitochondrial ribosome assembly. The investigation of METTL17 and other mitochondrial ribosome assembly factors is of both fundamental and practical significance, because defects in mitochondrial ribosome assembly are often associated with human mitochondrial diseases.

Abstract
Telomerase is a ribonucleoprotein complex, the main components of which are telomerase RNA and reverse transcriptase. Previously, it was shown in our laboratory that human telomerase RNA contains an open reading frame starting at adenine in position 176. The open reading frame encodes the hTERP protein, and the deletion of nucleotides 184-188 of human telomerase RNA disrupts the open reading frame and leads to the absence of hTERP. Human telomerase RNA has a conserved structure, changes in which affect telomerase activity. In this work, we have shown that the deletion of nucleotides 184-188 of telomerase RNA does not affect the functioning of telomerase.

Abstract
Ribosome biogenesis is consecutive coordinated maturation of ribosomal precursors in the nucleolus, nucleoplasm, and cytoplasm. The formation of mature ribosomal subunits involves hundreds of ribosomal biogenesis factors that ensure ribosomal RNA processing, tertiary structure, and interaction with ribosomal proteins. Although the main features and stages of ribosome biogenesis are conservative among different groups of eukaryotes, this process in human cells has become more complicated due to the larger size of the ribosomes and pre-ribosomes and intricate regulatory pathways affecting their assembly and function. Many of the factors involved in the biogenesis of human ribosomes have been identified using genome-wide screening based on RNA interference. A previous part of this review summarized recent data on the processing of the primary rRNA transcript and compared the maturation of the small 40S subunit in yeast and human cells. This part of the review focuses on the biogenesis of the large 60S subunit of eukaryotic ribosomes.

Abstract
The formation of eukaryotic ribosomes is a sequential process of ribosomal
precursors maturation in the nucleolus, nucleoplasm, and cytoplasm. Hundreds of
ribosomal biogenesis factors ensure the accurate processing and formation of
the ribosomal RNAs’ tertiary structure, and they interact with ribosomal
proteins. Most of what we know about the ribosome assembly has been derived
from yeast cell studies, and the mechanisms of ribosome biogenesis in
eukaryotes are considered quite conservative. Although the main stages of
ribosome biogenesis are similar across different groups of eukaryotes, this
process in humans is much more complicated owing to the larger size of the
ribosomes and pre-ribosomes and the emergence of regulatory pathways that
affect their assembly and function. Many of the factors involved in the
biogenesis of human ribosomes have been identified using genome-wide screening
based on RNA interference. This review addresses the key aspects of yeast and
human ribosome biogenesis, using the 40S subunit as an example. The mechanisms
underlying these differences are still not well understood, because, unlike
yeast, there are no effective methods for characterizing pre-ribosomal
complexes in humans. Understanding the mechanisms of human ribosome assembly
would have an incidence on a growing number of genetic diseases
(ribosomopathies) caused by mutations in the genes encoding ribosomal proteins
and ribosome biogenesis factors. In addition, there is evidence that ribosome
assembly is regulated by oncogenic signaling pathways, and that defects in the
ribosome biogenesis are linked to the activation of tumor suppressors.

Abstract
A lot of long non-coding RNAs (lncRNAs) are expressed in human cells in a number of transcripts of different lengths and composition of exons. In case of cancer-associated lncRNAs, an actual task is to determine their specific isoforms, since each transcript can perform its own function in carcinogenesis and might have a unique expression profile in various types of tumors. For the first time, we analyzed the expression of CASC8 lncRNA in human pancreatic ductal adenocarcinoma cell lines and found an abundant isoform that was previously considered as the minor one in this type of cancer. We also revealed extremely high expression levels of all CASC8 transcripts in MIA PaCa-2 cells and, conversely, the lack of this lncRNA in PANC-1. This allows to use them as convenient models for further in vitro studies.

Abstract
Apoptosis and autophagy are conserved processes that regulate cell survival and death under stress conditions. Apoptosis aims to remove cells from the body with minimal damage to surrounding tissues. Autophagy promotes removal of damaged organelles, protein aggregates, and cellular pathogens, stimulating cell survival. The signaling pathways involved in the regulation of apoptosis and autophagy largely overlap, leading to both competition and unidirectional interaction, which is of particular interest in investigating them as potential targets for cancer, autoimmune, and neurodegenerative disease therapies. This review analyzes the main pathways of molecular interactions between autophagy and apoptosis, which is necessary for understanding the mechanism maintaining the balance between cell death and survival under unfavorable conditions.

Abstract
Somatic Cell Nuclear Transfer (SCNT) technique was used to produce the first viable cloned cattle offspring in Russia. Whole-genome SNP genotyping confirmed that the cloned calf was identical to the fibroblast cell line that was used for SCNT. CRISPR/Cas9 approach was subsequently used to knock out genes for beta-lactoglobulin gene (PAEP) and the beta-lactoglobulin-like protein gene (LOC100848610) in the fibroblast cells. Gene editing (GE) efficiency was 4.4% for each of these genes. We successfully obtained single-cell-derived fibroblast colonies containing PAEP and LOC100848610 knockouts, which will be used to produce beta-lactoglobulin-deficient cattle.

Abstract
Long noncoding RNAs (lncRNAs) are promising biomarkers and potential targets for liver cancer therapy. Stable hepatocyte lines are used in vitro to investigate functions of lncRNAs which amount in cell fluctuates during carcinogenesis. For the first time we compared gene expression of known lncRNAs in human conditional normal liver cells HepaRG and cancer cell lines Huh7 and HepG2. We showed that relative amounts of these lncRNAs in HepaRG are close to analogous variables measured for liver samples from healthy donors. Obtained data demonstrate exclusive peculiarities of HepaRG and confirm its reasonable application as a model of normal human hepatocytes for studying functions of lncRNAs.

Abstract
Telomeres are special DNA-protein structures that are located at the ends of linear eukaryotic chromosomes. The telomere length determines the proliferation potential of cells. Telomerase is a key component of the telomere length maintenance system. While telomerase is inactive in the majority of somatic cells, its activity determines the clonogenic potential of stem cells as a resource for tissue and organism regeneration. Reactivation of telomerase occurs during the process of immortalization in the majority of cancer cells. Telomerase is a ribonucleoprotein that contains telomerase reverse transcriptase and telomerase RNA components. The RNA processing mechanism of telomerase involves exosome trimming or degradation of the primary precursor. Recent data provide evidence that the competition between the processing and decay of telomerase RNA may regulate the amount of RNA at the physiological level. We show that termination of human telomerase RNA transcription is dependent on its promoter, which engages with the multisubunit complex Integrator to interact with RNA polymerase II and terminate transcription of the human telomerase RNA gene followed by further processing.

Abstract
Telomerase is one of the major components of the telomeres -- linear eukaryotic chromosome ends - maintenance system. Linear chromosomes are shortened during each cell division due to the removal of the primer used for DNA replication. Special repeated telomere sequences at the very ends of linear chromosomes prevent the deletion of genome information caused by primer removal. Telomeres are shortened at each replication round until it becomes critically short and is no longer able to protect the chromosome in somatic cells. At this stage, a cell undergoes a crisis and usually dies. Rare cases result in telomerase activation, and the cell gains unlimited proliferative capacity. Special types of cells, such as stem, germ, embryonic cells and cells from tissues with a high proliferative potential, maintain their telomerase activity indefinitely. The telomerase is inactive in the majority of somatic cells. Telomerase activity in vitro requires two key components: telomerase reverse transcriptase and telomerase RNA. In cancer cells, telomerase reactivates due to the expression of the reverse transcriptase gene. Telomerase RNA expresses constitutively in the majority of human cells. This fact suggests that there are alternative functions to telomerase RNA that are unknown at the moment. In this manuscript, we review the biogenesis of yeasts and human telomerase RNAs thanks to breakthroughs achieved in research on telomerase RNA processing by different yeasts species and humans in the last several years.

Abstract
The non-coding and repetitive sequences constitute a great amount of higher eukaryotes genomes, but the elucidation of its role and mechanisms of action is now at the very beginning. Here we found, that internal telomeric repeats in Danio rerio are colocalized with some repetitive elements, namely, hAT and EnSpm repeats, which are highly represented in vertebrate genome. While investigating one of genome regions, containing two pairs of such repeats in close proximity we found, that it is transcribed. RNA-dependent structures, containing this sequence, were revealed in D. rerio fibroblast nuclei, which may serve as evidence of functional relevance of repetitive elements in genomes or of their transcripts.

Abstract
Telomerase synthesizes repetitive G-rich sequences (telomeric repeats) at the ends of eukaryotic chromosomes. This mechanism maintains the integrity of the genome, as telomere shortening leads to degradation and fusion of chromosomes. The core components of telomerase are the telomerase catalytic subunit and telomerase RNA, which possesses a small template region serving for the synthesis of a telomeric repeat. Mutations in the telomerase RNA are associated with some cases of aplastic anemia and also cause dyskeratosis congenita, myelodysplasia, and pulmonary fibrosis. Telomerase is active in 85% of cancers, and telomerase activation is one of the first steps in cell transformation. The study of telomerase and pathways where this enzyme is involved will help to understand the mechanism of the mentioned diseases and to develop new approaches for their treatment. In this review we describe the modern conception of telomerase RNA biosynthesis, processing, and functioning in the three most studied systems - yeast, vertebrates, and ciliates.

Abstract
Telomerase is an enzyme that maintains the length of the telomere. The telomere length specifies the number of divisions a cell can undergo before it finally dies (i.e. the proliferative potential of cells). For example, telomerase is activated in embryonic cell lines and the telomere length is maintained at a constant level; therefore, these cells have an unlimited fission potential. Stem cells are characterized by a lower telomerase activity, which enables only partial compensation for the shortening of telomeres. Somatic cells are usually characterized by the absence of telomerase activity. Telomere shortening leads to the attainment of the Hayflick limit, the transition of cells to a state of senescence. The cells subsequently enter a state of crisis, accompanied by massive cell death. The surviving cells become cancer cells, which are capable both of dividing indefinitely and maintaining telomere length (usually with the aid of telomerase). Telomerase is a reverse transcriptase. It consists of two major components: telomerase RNA (TER) and reverse transcriptase (TERT). TER is a non-coding RNA, and it contains the region which serves as a template for telomere synthesis. An increasing number of articles focussing on the alternative functions of telomerase components have recently started appearing. The present review summarizes data on the structure, biogenesis, and functions of telomerase.

Abstract
An attempt was made to identify molecular markers of different clinical stages of cervical carcinoma caused by papilloma virus (HPV). Presence of viral genome, telomerase level and expression of a gene, which coded the catalytic activity of that enzyme (hTERT), were assayed in 89 patients. HPV (type 16) genome harboring tumors were detected in 73% which was in conformity with the literature and our own data. Telomerase was identified (TRAP) in all tumors and tumor cells cultured in vitro. hTERT-specific RNA was found in all tumor samples, however, increase in its expression was insignificant. As far as the three markers are concerned, no significant differences between clinical stages of tumor were reported.

Abstract
Our aim was to investigate how replication protein A (RPA) in a wide range of concentration can regulate the activity of human telomerase. We used an in vitro system based on human cell extracts with or without RPA. It has been shown that removal of RPA leads to loss of telomerase activity and addition of RPA restores telomerase activity and at the same time promotes telomerase processivity. However, high excess of RPA inhibited telomerase processivity and caused the synthesis of relatively short DNA fragments (about 50-100 nucleotides). We assume that, together with other telomere-binding proteins, RPA may take part in activation of telomere overhang elongation by telomerase at a certain stage of a cell cycle as well as in regulation of telomere length.

Abstract
Nucleotide sequence changes increasing the number of paired bases without producing stable secondary structure elements in the 5'-untranslated region (5'-UTR) of the beta-globin mRNA had a slight effect on its translation in rabbit reticulocyte lysate at its low concentration and dramatically decreased translation efficiency at a high concentration. The removal of paired regions restored translation. Addition of purified eIF2 to the lysate resulted in equal translation efficiencies of templates differing in structure of 5'-UTR. A similar effect was observed for p50, a major mRNP protein. Other mRNA-binding initiation factors, eIF4F and eIF3B, had no effect on the dependence of translation efficiency on mRNA concentration. Analysis of the assembly of the 48S initiation complex from its purified components showed that less eIF2 is required for translation initiation on the beta-globin mRNA than on its derivative containing minor secondary structure elements in 5'-UTR. According to a model proposed, eIF2 not only delivers Met-tRNA, but it also stabilizes the complex of the 40S ribosome subunit with 5'-UTR, which is of particular importance for translation initiation on templates with structured 5'-UTR.
