Роман G-quadrulex motif в области поощрения человека МЕТ.

Известно, что гуанинобогатые нити протоонкогенных пропагандистов могут сворачиваться в структуры G-quadrulex для регулирования генного выражения. В МЕТ-промобилизаторе был выявлен параллельный внутримолекулярный G-quadrulex. Она выступает в качестве подавляющего устройства в регулировании выражения МЕТ. Вместе с тем весь богатый гуанином район в МЕТ-промобилизаторе образует гибридную параллельную/антипараллельную структуру G-quadrulex в физиологических условиях, что означает наличие в этом регионе некоторых противопараллельных и гибридных параллельных/антипараллельных структур G-quadrupllex.

Update on primary plasma cell leukemia.

Plasma cell leukemia (PCL) is a rare and highly aggressive plasma cell neoplasm developing in 0.5?4% of patients with multiple myeloma (MM). The diagnostic criteria were recently revised from 20% to ≥5% of circulating plasma cells in peripheral blood smears. PCL is classified as primary or secondary; primary PCL is when it presents in patients with no MM. Primary PCL shows clinical and laboratory features at presentation that differ from MM and exhibits a dismal prognosis even with the use of effective agents against MM. Therefore, intensive chemotherapy should be initiated immediately after d

Genetic architecture of multiple myeloma: From somatic alterations to germline susceptibility and clinical implications.

Multiple myeloma (MM) is best understood as a dynamically evolving genomic ecosystem shaped by inherited susceptibility, early oncogenic events, and continuous selective pressures. We propose an evolutionary genomics framework integrating germline risk, disease initiation, clonal diversification, and therapeutic adaptation into a unified model of MM biology. Polygenic risk burden, rare predisposing variants, and alterations in DNA repair and telomere pathways create a permissive background that influences precursor states and immune interactions. Primary cytogenetic events, particularly immuno

Протеин тиросин фосфатаза-рецептор типа каппа (ПТПРК) вернулся к рассмотрению: развивающееся понимание структуры, функций и патологии.

Protein Tyrosine Phosphataze Type Cappa (PTPRK) — мембранная тиросина фосфатаза, кодируемая часто удаляемой областью хромосомы 6q, которая играет ключевую роль в регулировании сигнала, сцепления и иммунной реакции клеток. Структурно PTPRK включает внеклеточную область, связанную с сцеплением клеток, область трансмембрана и две внутриклеточные каталитические области, ответственные за фосфатазу. В частности, PTPRK подвергается протеолитическому декольте с помощью Furin и ADAM10, в результате чего образуется внеклеточная подгруппа E и подгруппа P.

Adeno-associated virus as a delivery vector for gene therapy of human diseases.

Adeno-associated virus (AAV) has emerged as a pivotal delivery tool in clinical gene therapy owing to its minimal pathogenicity and ability to establish long-term gene expression in different tissues. Recombinant AAV (rAAV) has been engineered for enhanced specificity and developed as a tool for treating various diseases. However, as rAAV is being more widely used as a therapy, the increased demand has created challenges for the existing manufacturing methods. Seven rAAV-based gene therapy products have received regulatory approval, but there continue to be concerns about safely using high-dos

Агрессивная экстрамеуллярная миелома, представляющая собой маленькое препятствование.

De novo extramedullary multieloma (EMM) — редкая подмножество миеломы (MM), определяемая наличием клональных плазменных клеток (PC) за пределами костного мозга. Она связана с рефракторными заболеваниями и неблагоприятными последствиями. Даже в ЭММ плазменные цитомы внутри дуоденума, джеджунум и лилум редко встречаются при меньшем количестве 70 - случаи, о которых сообщается в литературе. Здесь мы представляем особо агрессивный случай ЭММ, который привел к тому, что маленький кишечник стал преградой для внутрисветовой плазмоцитомы во время лечения миэломы. Пациент прошел хирургическую пересечен

CD200 является мощным новым фактором роста в Мультимиломе, зависящим от сигнала рецептора IGF1.

CD200 — это иммунный контрольно-пропускной пункт, безошибочно выраженный в 70% недавно диагностированных пациентов с множественной миеломой (ММ) и связанный с плохим исходом. Выражение CD200 клетками опухоли препятствует иммунной реакции через взаимодействие с CD200R и участвует в устойчивости к иммунной терапии. Однако его роль в опухоли остается слабой. В этом исследовании мы показываем, что клетки MM, перевыражающие CD200, представляют собой значительное пролиферативное преимущество в свободных культурных сыворотках, средних и клоногенных анализах. Преимущество роста клеток, опосредованное

Mechanisms and Clinical Applications of Genome Instability in Multiple Myeloma.

Ongoing genomic instability represents a hallmark of multiple myeloma (MM) cells, which manifests largely as whole chromosome- or translocation-based aneuploidy. Importantly, although it supports tumorigenesis, progression and, response to treatment in MM patients, it remains one of the least understood components of malignant transformation in terms of molecular basis. Therefore these aspects make the comprehension of genomic instability a pioneering strategy for novel therapeutic and clinical speculations to use in the management of MM patients. Here we will review mechanisms mediating genom

Nanoparticles and bone microenvironment: a comprehensive review for malignant bone tumor diagnosis and treatment.

Malignant bone tumors, which are difficult to treat with current clinical strategies, originate from bone tissues and can be classified into primary and secondary types. Due to the specificity of the bone microenvironment, the results of traditional means of treating bone tumors are often unsatisfactory, so there is an urgent need to develop new treatments for malignant bone tumors. Recently, nanoparticle-based approaches have shown great potential in diagnosis and treatment. Nanoparticles (NPs) have gained significant attention due to their versatility, making them highly suitable for applica

Multi-omics tumor profiling technologies to develop precision medicine in multiple myeloma.

Multiple myeloma (MM), the second most common hematologic cancer, is caused by accumulation of aberrant plasma cells in the bone marrow. Its molecular causes are not fully understood and its great heterogeneity among patients complicates therapeutic decision-making. In the past decades, development of new therapies and drugs have significantly improved survival of MM patients. However, resistance to drugs and relapse remain the most common causes of mortality and are the major challenges to overcome. The advent of high throughput omics technologies capable of analyzing big amount of clinical a

Comprehensive molecular profiling of 718 Multiple Myelomas reveals significant differences in mutation frequencies between African and European descent cases.

Multiple Myeloma (MM) is a plasma cell malignancy with significantly greater incidence and mortality rates among African Americans (AA) compared to Caucasians (CA). The overall goal of this study is to elucidate differences in molecular alterations in MM as a function of self-reported race and genetic ancestry. Our study utilized somatic whole exome, RNA-sequencing, and correlated clinical data from 718 MM patients from the Multiple Myeloma Research Foundation CoMMpass study Interim Analysis 9. Somatic mutational analyses based upon self-reported race corrected for ancestry revealed significan

Advances in the assessment of minimal residual disease in mantle cell lymphoma.

The clinical impact of minimal residual disease detection at early time points or during follow-ups has been shown to accurately predict relapses among patients with lymphomas, mainly in follicular and diffuse large B cell lymphoma. The field of minimal residual disease testing in mantle cell lymphoma is still evolving but has great impact in determining the prognosis. Flow cytometry and polymerase chain reaction-based testing are most commonly used methods in practice; however, these methods are not sensitive enough to detect the dynamic changes that underline lymphoma progression. Newer meth

The novel role of circular RNA ST3GAL6 on blocking gastric cancer malignant behaviours through autophagy regulated by the FOXP2/MET/mTOR axis.

Gastric cancer (GC) ranks third in mortality among all cancers worldwide. Circular RNAs (circRNAs) play an important role in the occurrence and development of gastric cancer. Forkhead box P2 (FOXP2), as a transcription factor, is closely associated with the development of many types of tumours. However, the regulatory network between FOXP2 and circRNAs remains to be explored. In our study, circST3GAL6 was significantly downregulated in GC and was associated with poor prognosis in GC patients. Overexpression of circST3GAL6 inhibited the malignant behaviours of GC cells, which was mediated by in

Up-regulation of bone marrow stromal protein 2 (BST2) in breast cancer with bone metastasis.

BackgroundBone metastases are frequent complications of breast cancer. Recent literature implicates multiple chemokines in the formation of bone metastases in breast cancer. However, the molecular mechanism of metastatic bone disease in breast cancer remains unknown. We have recently made the novel observation of the BST2 protein expression in human breast cancer cell lines. The purpose of our present study is to investigate the expression and the role of BST2 in bone metastatic breast cancer.MethodscDNA microarray analysis was used to compare the BST2 gene expression between a metastatic to b

Case Report: longitudinal immunoglobulin abnormalities preceding IgA-λ MGUS and colonic DLBCL: a case suggesting immune-driven B-cell dysregulation.

Monoclonal gammopathy of undetermined significance (MGUS) is a common premalignant condition typically associated with progression to plasma cell disorders. Research suggests that MGUS may also coexist with or precede other lymphoid malignancies, potentially reflecting shared mechanisms involving chronic immune dysregulation. We report a 73-year-old man with more than 10 years of long-standing polyclonal immunoglobulin elevation, who subsequently developed IgA-λ MGUS and was later diagnosed with primary colonic diffuse large B-cell lymphoma (DLBCL). Molecular analysis identified mutations in T
