Review ArticleOpen accessJAK Inhibitors for Rheumatoid Arthritis: Assessing Efficacy and Safety in TreatmentAnastasia V. Poznyak, Varvara A Orekhova, Natalia Vladimirovna Elizova et al.Rheumatoid Arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation, progressive joint destruction, and systemic complications. Dysregulated cytokine signaling through the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway plays a central role in RA pathogenesis, making JAK inhibitors an important therapeutic option. Tofacitinib, baricitinib, and upadacitinib are oral targeted synthetic disease-modifying antirheumatic drugs that interfere with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 8 Oct 2026 · 430 accessesView PDF Cite

Review ArticleOpen accessThe Intricate Relationship between Obesity and Type 2 DiabetesAnastasia V. Poznyak, Elizaveta M. Pleshko, Aleksandra S. Utkina et al.The rising prevalence of obesity and type 2 diabetes mellitus (T2DM) has emerged as one of the most pressing global public health challenges, profoundly impacting various demographic groups worldwide. This review synthesizes recent epidemiological data and explores the intricate biochemical mechanisms linking obesity to T2DM. We highlight the multifactorial nature of obesity, characterized by excessive adipose tissue, systemic inflammation, and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 9 Aug 2026 · 459 accessesView PDF Cite

Literature ReviewOpen accessMicroRNAs in Atherosclerosis: Key Players, Diagnostic Potential, and Therapeutic OpportunitiesAnastasia V Poznyak, Stanislav Anatolievich Antonov, Ulyana V. Rozhkova et al.Atherosclerosis is a significant contributor to cardiovascular diseases, often progressing silently over many years before clinical symptoms manifest. The multifaceted pathogenesis of atherosclerosis, involving processes such as endothelial dysfunction and inflammation, presents challenges in early diagnosis and effective treatment. MicroRNAs (miRNAs), a class of non-coding RNA molecules with post-transcriptional gene regulation abilities, have emerged as potential key players in atherosclerosis … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 25 Jul 2026 · 744 accessesView PDF Cite

Literature ReviewOpen accessUnraveling NETosis: From Immune Mechanisms to Therapeutic InnovationsAnastasia V. Poznyak, Alexey V. Churov, Gulalek Amanmyradovna Babayeva et al.Neutrophil Extracellular Traps (NETs) are integral to immune responses, serving both protective and pathological roles in inflammatory diseases. Despite increasing recognition of NETs, significant gaps remain in understanding the nuanced mechanisms of NETosis and its implications for health and disease. This review systematically explores NETosis—the formation of NETs—by elucidating the molecular signaling pathways and cellular mechanisms involved. We highlight the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 21 Feb 2026 · 1,685 accessesView PDF Cite

Literature ReviewOpen accessCorrelation of Atherosclerosis and Osteoarthritis, the Role of Inflammation in the Pathogenesis of Osteoarthritis and AtherosclerosisAnastasia V. Poznyak, Nikolay A. Orekhov, Aleksandra Sergeevna Utkina et al.Cardiovascular Diseases (CVD) rank among the leading causes of death globally, accounting for a substantial proportion of mortality rates and affecting millions of individuals. Risk factors such as ageing, obesity, diabetes and a sedentary lifestyle contribute significantly to the prevalence of CVD. Osteoarthritis (OA), on the other hand, is one of the most common joint disorders, affecting a large segment … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 15 Feb 2026 · 1,777 accessesView PDF Cite

Literature ReviewOpen accessPotential Therapies for Mitochondrial Diseases Caused by mtDNA MutationsAnastasia V. Poznyak, Nikolay A. Orekhov, Dmitry Felixovich Beloyartsev et al.Mitochondrial diseases, caused by mutations in mitochondrial DNA (mtDNA), present significant genetic and clinical complexities that challenge accurate diagnosis and treatment. This review examines the critical molecular mechanisms underlying these disorders, particularly the role of heteroplasmy, where mixtures of mutated and normal mtDNA influence disease severity, and the nuclear-mitochondrial DNA interactions that compound diagnostic and therapeutic challenges. The threshold effect, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,750 accessesView PDF Cite

Review ArticleOpen accessTheory and Strategies of Atherosclerotic Renal Artery Stenosis TreatmentAnastasia V. Poznyak, Nikolay A. Orekhov, Gulalek Amanmyradovna Babayeva et al.Atherosclerosis is a disease that affects large arteries and contributes to the development of cardiovascular disease and adverse events. The main characteristic of this disease is the formation of plaques that narrow the lumen of the vessel. However, atherosclerosis is not the only cause of vasoconstriction. For example, various causes may be involved in renal artery stenosis, such as vasculitis … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 4 Jan 2026 · 1,862 accessesView PDF Cite
