Структурная основа для селективного метилирования 5-carboxymethoxyuridine В модификацию tRNA.

Постранарные модификации tRNA широко сохранены во всех сферах жизни. Особенно те из них, которые происходят в антикодоне, часто модифицируют эффективность перевода. Производственные показатели 5-hydroxyuridine конкретно встречаются в бактериальных тРНК, где 5-methoxyuridine и 5-carboxymethoxyuridine , являются основными видами бактерий с положительной и отрицательной массой, соответственно. В некоторых видах тРНК, 5- Карбоксиметоксиуридин может быть дополнительно метилирован CMOM для образования метилэстера. В этом докладе мы представляем рентгеновскую кристаллическую структуру Escherichia col

Activation of p53/miR-34a Tumor Suppressor Axis by Chinese Herbal Formula JP-1 in A549 Lung Adenocarcinoma Cells.

Lung cancer is the leading cause of cancer death worldwide; the most common pathologic type is lung adenocarcinoma (LADC). In spite of the recent progress in targeted therapy, most LADC patients eventually expired due to the inevitable recurrence and drug resistance. New complementary agent with evidence-based molecular mechanism is urgently needed. MiR-34a is an important p53 downstream tumor suppressor, which regulates apoptosis, cell-cycle, EMT (epithelial mesenchymal transition), and so forth. Its expression is deficient in many types of cancers including LADC. Here, we show that a Chinese

Nanotechnology and Matrix Metalloproteinases in Cancer Diagnosis and Treatment.

Cancer is still one of the leading causes of death worldwide. This great mortality is due to its late diagnosis when the disease is already at advanced stages. Although the efforts made to develop more effective treatments, around 90% of cancer deaths are due to metastasis that confers a systemic character to the disease. Likewise, matrix metalloproteinases (MMPs) are endopeptidases that participate in all the events of the metastatic process. MMPs' augmented concentrations and an increased enzymatic activity have been considered bad prognosis markers of the disease. Therefore, synthetic inhib

Tubulin binding potentially clears up Bortezomib and Carfilzomib differential neurotoxic effect.

Proteasome inhibitors (PIs) represent the gold standard in the treatment of multiple myeloma. Among PIs, Bortezomib (BTZ) is frequently used as first line therapy, but peripheral neuropathy (PN), occurring approximately in 50% of patients, impairs their life, representing a dose-limiting toxicity. Carfilzomib (CFZ), a second-generation PI, induces a significantly less severe PN. We investigated possible BTZ and CFZ off-targets able to explain their different neurotoxicity profiles. In order to identify the possible PIs off-targets we used the SPILLO-PBSS software that performs a structure-base

Neurodegeneration: can metabolites from Eremurus persicus help?

The number of patients affected by neurodegenerative diseases is increasing worldwide, and no effective treatments have been developed yet. Although precision medicine could represent a powerful tool, it remains a challenge due to the high variability among patients. To identify molecules acting with innovative mechanisms of action, we performed a computational investigation using SAFAN technology, focusing specifically on HuD. This target belongs to the human embryonic lethal abnormal visual-like (ELAV) proteins and plays a key role in neuronal plasticity and differentiation. The results high

Ранние синапсовые изменения фоторецептора Mitochondria в модели мыши Множественного склероза EAE

Множественный склероз (MS) — воспалительное аутоиммунное заболевание центральной нервной системы (CNS), связанное со многими неврологическими нарушениями. Взгляд на систему часто нарушается в MS. В предыдущих исследованиях мы наблюдали ранние синусосы фоторецепторовых лент в модели мыши EAE MS, которые включали изменения в цикле синаптического везикла и нарушения предсинаптического ка2+ гомеостаза. Поскольку эти преднаптические события требуют очень много энергии, мы проанализировали, может ли синаптическая митохондрия, играющая важную роль в синаптическом энергетическом метаболизме, быть заде

From Nature to Synthetic Compounds: Novel 1(N),2,3 Trisubstituted-5-oxopyrrolidines Targeting Multiple Myeloma Cells.

The insurgence of drug resistance in treating Multiple Myeloma (MM) still represents a major hamper in finding effective treatments, although over the past decades new classes of drugs, such as proteasome inhibitors and immunomodulatory drugs, have been discovered. Recently, our research team, within a Nature-Aided Drug Discovery project, isolated from Hibiscus Sabdariffa L. calyces the secondary metabolite called Hib-ester which possesses antiproliferative properties against human multiple myeloma RPMI 8226 cells, reduces migration and cell invasion and inhibits proteasome without neurotoxic

Bisphosphonate conjugation for bone specific drug targeting.

Bones provide essential functions and are sites of unique biochemistry and specialized cells, but can also be sites of disease. The treatment of bone disorders and neoplasia has presented difficulties in the past, and improved delivery of drugs to bone remains an important goal for achieving effective treatments. Drug targeting strategies have improved drug localization to bone by taking advantage of the high mineral concentration unique to the bone hydroxyapatite matrix, as well as tissue-specific cell types. The bisphosphonate molecule class binds specifically to hydroxyapatite and inhibits

A Review of Recent Curcumin Analogues and Their Antioxidant, Anti-Inflammatory, and Anticancer Activities.

Curcumin, as the main active component of turmeric (Curcuma longa), has been demonstrated with various bioactivities. However, its potential therapeutic applications are hindered by challenges such as poor solubility and bioavailability, rapid metabolism, and pan-assay interference properties. Recent advancements have aimed to overcome these limitations by developing novel curcumin analogues and modifications. This brief review critically assesses recent studies on synthesising different curcumin analogues, including metal complexes, nano particulates, and other curcumin derivatives, focused o

Malignant mesothelioma tumours: molecular pathogenesis, diagnosis, and therapies accompanying clinical studies.

The pathetic malignant mesothelioma (MM) is a extremely uncommon and confrontational tumor that evolves in the mesothelium layer of the pleural cavities (inner lining- visceral pleura and outer lining- parietal pleura), peritoneum, pericardium, and tunica vaginalis and is highly resistant to standard treatments. In mesothelioma, the predominant pattern of lesions is a loss of genes that limit tumour growth. Despite the worldwide ban on the manufacture and supply of asbestos, the prevalence of mesothelioma continues to increase. Mesothelioma presents and behaves in a variety of ways, making dia

Metabolic Reprogramming of Cancer Cells and Therapeutics Targeting Cancer Metabolism.

BackgroundCancer metabolism is a field focused on the unique alterations in metabolic pathways that occur in cancer cells, distinguishing them from the metabolic processes in normal cells.MethodsAn extensive review of the current literature on the metabolic adaptation of cancer cells was carried out in the current study.ResultsThe rapidly proliferating cells require high levels of molecules, such as glucose, amino acids, lipids, and nucleotides, along with increased energy demand (ATP). These requirements are met through alterations in the processes involving glucose, amino acid, lipid, and nu

Landscape of small nucleic acid therapeutics: moving from the bench to the clinic as next-generation medicines.

The ability of small nucleic acids to modulate gene expression via a range of processes has been widely explored. Compared with conventional treatments, small nucleic acid therapeutics have the potential to achieve long-lasting or even curative effects via gene editing. As a result of recent technological advances, efficient small nucleic acid delivery for therapeutic and biomedical applications has been achieved, accelerating their clinical translation. Here, we review the increasing number of small nucleic acid therapeutic classes and the most common chemical modifications and delivery platf
