Отличительные стратегии распознавания tRNA, используемые гомологической семьей редактирующих доменов, предотвращают неправильный перевод.

Ошибки в синтезе белка из-за пропускания аминокислот с tRNA ставят под угрозу жизнеспособность клеток. Было описано несколько контрольно-пропускных пунктов для предотвращения образования Ala- и Cys-tRNA(Pro), в том числе специально для Ala редактируемый домен (INS) большинства бактериальных проли-тринских синтезаторов (PRS) и автономный однодомный INS homolog, YbaK, который очищает Cys-tRNA(Pro) в транс. Во многих видах, где у ПРОРС нет домена INS, за редактирование Ala-tRNA(ProXp-ala) отвечает другой однодомный белок, похожий на INS. Хотя аминокислотная специфичность этих доменов редактирован

Targeting Cancer Through Thymoquinone: From Molecular Mechanisms to Clinical Prospects.

Thymoquinone (TQ), the active compound in Nigella sativa (black seed), has shown promising effects against cancer in many laboratory studies. In this review, we explore how TQ works on different aspects of cancer, from stopping cancer cell growth and spread, to triggering cancer cell death, reducing inflammation, and helping the immune system fight back. We also highlight how TQ may overcome one of the biggest problems in cancer treatment-chemoresistance. When used together with common treatments like chemotherapy, radiation, or immunotherapy, TQ has been shown to improve their effects and red

Current and emerging treatment options for patients with relapsed myeloma.

Multiple myeloma (MM) is a neoplastic disorder. It results from proliferation of clonal plasma cells in bone marrow with production of monoclonal proteins, which are detectable in serum or urine. MM is clinically characterized by destructive bone lesions, anemia, hypercalcemia and renal insufficiency. Its prognosis is severe, with a median survival after diagnosis of approximately 3 years due to frequent relapses. Treatments for patients with relapsed/refractory MM include hematopoietic cell transplantation, a rechallenge using a previous chemotherapy regimen or a trial of a new regimen. The i

The impact of myelosuppression on quality of life of patients treated with chemotherapy.

Side effects from chemotherapy-induced myelosuppression can negatively affect patients' quality of life (QoL). Neutropenia increases infection risk, and anemia frequently results in debilitating fatigue. Additionally, the bleeding risk associated with thrombocytopenia can lead to fear and anxiety. However, traditional interventions for myelosuppression fall short of the ideal. Granulocyte colony-stimulating factors reduce the risk of severe neutropenia but commonly lead to bone pain. Erythropoiesis-stimulating agents are not always effective and may cause thromboembolic events, while transfusi

С-терминальный связывающий белок 2 - новый дезинфицирующий опухоль, направленный на MYC-IRF4 ось в множестве миеломы.

Клетки с множественной миеломой (MM) подвержены зависимости от MYC, а их непосредственные цели по трансактивации IRF4 направлены на распространение и выживание. MYC и IRF4 по-прежнему считаются "ненаркоманными", поскольку большинство мелких ингибиторов молекулярного происхождения страдают от низкой производительности, неоптимальных фармакокинетических свойств и нежелательных нецелевых эффектов. Косвенное подавление MYC/IRF4 проявляется в качестве терапевтической уязвимости MM. Здесь мы обнаружили неоцененную опухоль, впечатляющую роль связующего белка С-терминала 2 (CTBP2) в MM путем сильного

Molecular Evaluation of Low-grade Low-stage Endometrial Cancer With and Without Recurrence.

Low-grade, low-stage endometrioid carcinomas (LGLS EC) demonstrate 5-yr survival rates up to 95%. However, a small subset of these tumors recur, and little is known about prognostic markers or established mutation profiles associated with recurrence. The goal of the current study was to identify the molecular profiles of the primary carcinomas and the genomic differences between primary tumors and subsequent recurrences. Four cases of LGLS EC with recurrence and 8 cases without recurrence were evaluated via whole-exome sequencing. Three of the 4 recurrent tumors were evaluated via Oncomine Com

A Systematic Review of the Effects of Bisphosphonates on Osteoblasts In Vitro.

Bisphosphonates (BPs) are widely used to treat bone disorders, prevent skeletal-related events, and manage bone metastasis. These drugs are synthetic analogs of pyrophosphate and primarily function by inhibiting osteoclast activity. However, increasing evidence suggests that they also have an effect on osteoblasts. This systematic review aims to evaluate how bisphosphonates affect osteoblasts by summarizing findings from in vitro studies on the impact of BPs on osteoblast lineage cells, addressing the following question: "Do bisphosphonates affect osteoblast cell lineage function?". For this p

Trial watch: beta-blockers in cancer therapy.

Compelling evidence supports the hypothesis that stress negatively impacts cancer development and prognosis. Irrespective of its physical, biological or psychological source, stress triggers a physiological response that is mediated by the hypothalamic-pituitary-adrenal axis and the sympathetic adrenal medullary axis. The resulting release of glucocorticoids and catecholamines into the systemic circulation leads to neuroendocrine and metabolic adaptations that can affect immune homeostasis and immunosurveillance, thus impairing the detection and eradication of malignant cells. Moreover, catech

Alterations in macrophage polarization in the craniofacial and extracranial skeleton after zoledronate application and surgical interventions - an in vivo experiment.

PURPOSE: Medication-related osteonecrosis occurs exclusively in the jaw bones. However, the exact pathogenesis of medication-related osteonecrosis of the jaw (MRONJ) and the unique predisposition of the jaw bones have not been elucidated, making its treatment a challenge. Recent evidence indicates that macrophages might play a pivotal role in MRONJ pathogenesis. The aim of the present study was to compare the macrophage populations between the craniofacial and extracranial skeleton and to investigate the changes induced by zoledronate (Zol) application and surgical interventions. MATERIALS AN

BET bromodomain protein inhibition is a therapeutic option for medulloblastoma.

Medulloblastoma is the most common malignant brain tumor of childhood, and represents a significant clinical challenge in pediatric oncology, since overall survival currently remains under 70%. Patients with tumors overexpressing MYC or harboring a MYC oncogene amplification have an extremely poor prognosis. Pharmacologically inhibiting MYC expression may, thus, have clinical utility given its pathogenetic role in medulloblastoma. Recent studies using the selective small molecule BET inhibitor, JQ1, have identified BET bromodomain proteins, especially BRD4, as epigenetic regulatory factors for

Effects of the polyunsaturated fatty acids, EPA and DHA, on hematological malignancies: a systematic review.

Omega-3 polyunsaturated fatty acids (PUFAs) have well established anti-cancer properties. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are among this biologically active family of macromolecules for which various anti-cancer effects have been explained. These PUFAs have a high safety profile and can induce apoptosis and inhibit growth of cancer cells both in vitro and in vivo, following a partially selective manner. They also increase the efficacy of chemotherapeutic agents by increasing the sensitivity of different cell lines to specific anti-neoplastic drugs. Various mechanisms

Диагностический вызов надпочечной массы в множестве миэломы: случай ганглионевромы.

Адренальная ганглионеврома — это редкий доброкачественная опухоль, которая часто обнаруживается случайно и может представлять серьезную диагностическую проблему из-за ее неконкретных особенностей. Эта трудность особенно проявляется у пациентов с известной злоумышленностью, у которых адренальная масса более легко интерпретируется как метастатическая или плазменная болезнь. Мы сообщаем о пациенте с множественной миеломой, в котором была обнаружена случайная адренальная масса во время установки вычисленной томографии. Находки неопределены и вызывают подозрения по поводу адренального метастаза или
