Gene regulation by non-Coding RNAs in infertility: a mechanistic review.

Infertility is a significant global health issue affecting millions of couples, with noncoding RNAs (ncRNAs) emerging as pivotal regulators in reproductive biology. This review explores the roles of various ncRNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), long noncoding RNAs (lncRNAs), PIWI-interacting RNAs (piRNAs), and circular RNAs (circRNAs) in male and female infertility. These ncRNAs modulate critical processes such as spermatogenesis, oogenesis, follicular development, and embryo implantation through mechanisms like post-transcriptional regulation, chromatin remode

Вирусная инфекция Эпштейна-Барра поощряет диагностику Т клеток в гуманизированной модели мыши множественного склероза.

Скрытая инфекция вируса Эпштейн-Барр (ЭБВ) является серьезным фактором риска для развития множественных склерозов (МС), хотя основополагающие механизмы остаются неясными. Для изучения этой связи мы спровоцировали экспериментальный аутоиммунный энцефаломиелит (EAE) в мышах с иммунодефицитными мышами, восстановленных с периферийными моноядерными клетками крови (PBMC) у лиц, которые имели или не имели историю заражения EBV и/или повторного образования MS (RMS). Мыши HuPBMC EAE, генерируемые EBV-серонегативными здоровыми донорами, были менее восприимчивы к возникновению серьезных неврологических с

Advances in CRISPR-Cas technology and its applications: revolutionising precision medicine.

CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-associated proteins) has undergone marked advancements since its discovery as an adaptive immune system in bacteria and archaea, emerged as a potent gene-editing tool after the successful engineering of its synthetic guide RNA (sgRNA) toward the targeting of specific DNA sequences with high accuracy. Besides its DNA editing ability, further-developed Cas variants can also edit the epigenome, rendering the CRISPR-Cas system a versatile tool for genome and epigenome manipulation and a pioneering force in precision medic

The Role of Cullin-RING Ligases in Striated Muscle Development, Function, and Disease.

The well-orchestrated turnover of proteins in cross-striated muscles is one of the fundamental processes required for muscle cell function and survival. Dysfunction of the intricate protein degradation machinery is often associated with development of cardiac and skeletal muscle myopathies. Most muscle proteins are degraded by the ubiquitin-proteasome system (UPS). The UPS involves a number of enzymes, including E3-ligases, which tightly control which protein substrates are marked for degradation by the proteasome. Recent data reveal that E3-ligases of the cullin family play more diverse and c

Географическая связь множественного склероза и амиотропического бокового склероза.

Амиотрофический боковой склероз (ALS) и множественный склероз (MS) являются разрушительными, неизлечимыми нейродегенеративными заболеваниями, которые в значительной степени считаются неизвестными этиологами. Хотя эти болезни имеют некоторые сходства, они, как правило, не считаются тесно связанными между собой. У них разные патологические маркеры и разные прогнозы. Кроме того, MS (но не ALS) считается аутоиммунным заболеванием. Кроме того, уже давно отмечается, что НР имеет мощный градиент север-юг в своем распределении, в то время как лишь недавно стало известно о таком градиенте в БАС. Вместе

Pro- and Antioxidant Effects of Vitamin C in Cancer in correspondence to Its Dietary and Pharmacological Concentrations.

Vitamin C is an antioxidant that may scavenge reactive oxygen species preventing DNA damage and other effects important in cancer transformation. Dietary vitamin C from natural sources is taken with other compounds affecting its bioavailability and biological effects. High pharmacological doses of vitamin C may induce prooxidant effects, detrimental for cancer cells. An oxidized form of vitamin C, dehydroascorbate, is transported through glucose transporters, and cancer cells switch from oxidative phosphorylation to glycolysis in energy production so an excess of vitamin C may limit glucose tr

DHCR24 in Tumor Diagnosis and Treatment: A Comprehensive Review.

As an important nutrient in the human body, cholesterol can not only provide structural components for the body's cells, but also can be transformed into a variety of active substances to regulate cell signaling pathways. As an important cholesterol synthase, DHCR24 participates in important regulatory processes in the body. The application of DHCR24 in tumor clinical diagnosis and treatment also attracts much attention. This article reviews the structure and regulatory characteristics of DHCR24, and the research of DHCR24 on tumor progression. We summarize the possible mechanisms of DHCR24 pr

Update of early phase clinical trials in cancer immunotherapy.

Immunotherapy has revolutionized the landscape of cancer treatment and become a standard pillar of the treatment. The two main drivers, immune checkpoint inhibitors and chimeric antigen receptor T cells, contributed to this unprecedented success. However, despite the striking clinical improvements, most patients still suffer from disease progression because of the evolution of primary or acquired resistance. This mini-review summarizes new treatment options including novel targets and interesting combinational approaches to increase our understanding of the mechanisms of the action of and resi

Unc-51 like kinase 3 (ULK3) contributes to autophagy and cell survival in multiple myeloma.

Despite effective therapies such as proteasome inhibitors, multiple myeloma (MM) patients relapse with refractory disease. Analysis of RNA sequencing data from CD138 + MM patient cells (n = 813) across disease stages identifies an autophagy gene signature. Particularly elevated ULK3 expression is strongly associated with disease progression. Functional studies reveal that ULK3 supports MM cell survival via the ULK-ATG13-FIP200 complex. We generate small-molecule kinase inhibitors (SG3-014/MA9-060) exhibiting nanomolar potency against ULK3, with binding confirmed by co-crystallization. While ex

Short and Long Non-Coding RNAs in Renal Cell Carcinoma.

Renal cell carcinoma (RCC) represents the most frequent kidney malignancy and remains a major clinical challenge due to its often silent onset, high metastatic potential, and limited responsiveness to conventional chemotherapy. Increasing evidence indicates that non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are key regulators of RCC tumorigenesis, progression, and therapy resistance. Rather than providing a purely descriptive overview, this review focuses on emerging mechanistic paradigms through which ncRNAs actively shap

C-Reactive Protein: Pathophysiology, Diagnosis, False Test Results and a Novel Diagnostic Algorithm for Clinicians.

The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of

Stage-specific treatment of colorectal cancer: A microRNA-nanocomposite approach.

Colorectal cancer (CRC) is among the leading causes of cancer mortality. The lifetime risk of developing CRC is about 5% in adult males and females. CRC is usually diagnosed at an advanced stage, and at this point therapy has a limited impact on cure rates and long-term survival. Novel and/or improved CRC therapeutic options are needed. The involvement of microRNAs (miRNAs) in cancer development has been reported, and their regulation in many oncogenic pathways suggests their potent tumor suppressor action. Although miRNAs provide a promising therapeutic approach for cancer, challenges such as

Significance of long chain polyunsaturated fatty acids in human health.

In the last decades, the development of new technologies applied to lipidomics has revitalized the analysis of lipid profile alterations and the understanding of the underlying molecular mechanisms of lipid metabolism, together with their involvement in the occurrence of human disease. Of particular interest is the study of omega-3 and omega-6 long chain polyunsaturated fatty acids (LC-PUFAs), notably EPA (eicosapentaenoic acid, 20:5n-3), DHA (docosahexaenoic acid, 22:6n-3), and ARA (arachidonic acid, 20:4n-6), and their transformation into bioactive lipid mediators. In this sense, new familie
