Различия между мужчинами и женщинами-неврофилами, в отношении которых в полиомиках присутствуют РНК.

КОЛИЧЕСТВО: Мужчины и женщины демонстрируют различия в распространенности связанных с нейтрофильом заболеваний, таких, как системная волчанка, эритематос, ревматоидный артрит и множественный склероз, а также различия в нейтрофильных физиологических реакциях, таких, как реакция на инфекцию, повреждение тканей и химотактические факторы. Однако мало что известно об основах различий по признаку пола среди нейтрофилов. МЕТОДЫ: Начиная с людей, нейтрофилов от здоровых доноров, мы использовали RNA-seq для изучения общих профилей RNA, RNA, не связанных с рибосом и, следовательно, не переведенных, RNA

The KISS1 Receptor as an In Vivo Microenvironment Imaging Biomarker of Multiple Myeloma Bone Disease.

Multiple myeloma is one of the most common hematological diseases and is characterized by an aberrant proliferation of plasma cells within the bone marrow. As a result of crosstalk between cancer cells and the bone microenvironment, bone homeostasis is disrupted leading to osteolytic lesions and poor prognosis. Current diagnostic strategies for myeloma typically rely on detection of excess monoclonal immunoglobulins or light chains in the urine or serum. However, these strategies fail to localize the sites of malignancies. In this study we sought to identify novel biomarkers of myeloma bone di

Аккумулирование опустошающих липидов в Arf1-Ablanted Neurorons способствует нейродегенерации с помощью mtDNA и активации воспаляющих путей в Микроглии.

В нейронах и глиальных клетках были обнаружены липидные метаболические расстройства у пациентов с нейродегенеративной (ND) и животных. Однако патологическая связь между липидными капельками и НУ остается слабой. Недавняя работа высветила полезность модели мыши Arf1-knockout с учетом особенностей нейронов и соответствующих клеток для разъяснения связи между расстройствами липидного метаболизма и амиотропическим боковым склерозом (ALS) и множественным склерозом (MS). В этом исследовании было установлено, что недостача арф1 вызвала первичный синтез избытка жирной кислоты через ось АКТ-mTORC1-SREB

Fasting boosts breast cancer therapy efficacy via glucocorticoid activation.

The majority of breast cancers are driven by oestrogen receptor-α (ERα) activation, and endocrine therapy represents the mainstay treatment for these patients1. However, resistance is common and tumours often progress after years of endocrine suppression2. Periodic fasting enhances the efficacy of standard endocrine therapy and delays acquired drug resistance, although the underlying mechanisms remain unclear3. Here we show that fasting induces extensive epigenetic reprogramming in ERα-positive breast cancer xenografts when combined with endocrine therapy, with large-scale activation of glucoc

Oncofetal Chondroitin Sulfate Is a Highly Expressed Therapeutic Target in Non-Small Cell Lung Cancer.

Broad-spectrum therapeutics in non-small cell lung cancer (NSCLC) are in demand. Most human solid tumors express proteoglycans modified with distinct oncofetal chondroitin sulfate (CS) chains that can be detected and targeted with recombinant VAR2CSA (rVAR2) proteins and rVAR2-derived therapeutics. Here, we investigated expression and targetability of oncofetal CS expression in human NSCLC. High oncofetal CS expression is associated with shorter disease-free survival and poor overall survival of clinically annotated stage I and II NSCLC patients (n = 493). Oncofetal CS qualifies as an independ

Fucoidan Structure and Activity in Relation to Anti-Cancer Mechanisms.

Fucoidan is a natural derived compound found in different species of brown algae and in some animals, that has gained attention for its anticancer properties. However, the exact mechanism of action is currently unknown. Therefore, this review will address fucoidans structure, the bioavailability, and all known different pathways affected by fucoidan, in order to formulate fucoidans structure and activity in relation to its anti-cancer mechanisms. The general bioactivity of fucoidan is difficult to establish due to factors like species-related structural diversity, growth conditions, and the ex

Escherichia coli in the production of biopharmaceuticals.

Escherichia coli has shouldered a massive workload with the discovery of recombinant DNA technology. A new era began in the biopharmaceutical industry with the production of insulin, the first recombinant protein, in E. coli and its use in treating diabetes. After insulin, many biopharmaceuticals produced from E. coli have been approved by the US Food and Drug Administration and the European Medicines Agency to treat various human diseases. Although E. coli has some disadvantages, such as lack of post-translational modifications and toxicity, it is an important host with advantages such as bei

Identification of Novel Sphydrofuran-Derived Derivatives with Lipid-Lowering Activity from the Active Crude Extracts of Nocardiopsis sp. ZHD001.

Lipid-lowering is one of the most effective methods of prevention and treatment for cardiovascular diseases. However, most clinical lipid-lowering drugs have adverse effects and cannot achieve the desired efficacy in some complex hyperlipidemia patients, so it is of great significance to develop safe and effective novel lipid-lowering drugs. In the course of our project aimed at discovering the chemical novelty and bioactive natural products of marine-derived actinomycetes, we found that the organic crude extracts (OCEs) of Nocardiopsis sp. ZHD001 exhibited strong in vivo efficacies in reducin

Synthesis and biological evaluation of a new polymeric conjugate and nanocarrier with osteotropic properties.

Bone-seeking (osteotropic) drug delivery systems (ODDS) represent an interesting solution for targeting different types of drugs to the bones. In particular, anticancer and antibacterial agents could take advantage of such therapeutic strategy. We have recently developed an innovative approach to this aim: a new osteotropic biomaterial was prepared, based on the conjugation of a poly(lactide-co-glycolide) (PLGA) with the bisphosphonate drug alendronate (PLGA-ALE); its hemo- and cytocompatibility were verified. Starting with this copolymer, an osteotropic nanoparticle system (NP) was produced f

Perspective Applications and Associated Challenges of Using Nanocellulose in Treating Bone-Related Diseases.

Bone serves to maintain the shape of the human body due to its hard and solid nature. A loss or weakening of bone tissues, such as in case of traumatic injury, diseases (e.g., osteosarcoma), or old age, adversely affects the individuals quality of life. Although bone has the innate ability to remodel and regenerate in case of small damage or a crack, a loss of a large volume of bone in case of a traumatic injury requires the restoration of bone function by adopting different biophysical approaches and chemotherapies as well as a surgical reconstruction. Compared to the biophysical and chemothe

1'-Acetoxyeugenol Acetate Isolated from Thai Ginger Induces Apoptosis in Human Ovarian Cancer Cells by ROS Production via NADPH Oxidase.

The rhizomes of Alpinia galanga (Thai ginger) have been used extensively as a spice in Southeast Asian and Arabian cuisines and reported to possess a wide range of biological properties, such as antioxidant, antimicrobial, and antibacterial. However, the specific molecular and cellular mechanisms underlying the anti-tumor effects induced by Thai ginger and its corresponding active compounds have been poorly characterized. We found that upon EtOH extraction, Thai ginger extract exhibits cytotoxic activity (IC50 < 10 μg/mL) and triggers cell death via caspase-dependent apoptosis in human ovarian

Unlocking the Therapeutic Potential of Algae-Derived Compounds in Hematological Malignancies.

Algae are a rich source of bioactive compounds that have a wide range of beneficial effects on human health and can show significant potential in the treatment of hematological malignancies such as leukemia, lymphoma, and multiple myeloma. These diseases often pose a therapeutic challenge despite recent advances in treatment (e.g., the use of immunomodulatory drugs, proteasome inhibitors, CD38 monoclonal antibodies, stem cell transplant, and targeted therapy). A considerable number of patients experience relapses or resistance to the applied therapies. Algal compounds, alone or in combination

Current Perspectives of the Applications of Polyphenols and Flavonoids in Cancer Therapy.

The development of anticancer therapies that involve natural drugs has undergone exponential growth in recent years. Among the natural compounds that produce beneficial effects on human health, polyphenols have shown potential therapeutic applications in cancer due to their protective functions in plants, their use as food additives, and their excellent antioxidant properties. The possibility of combining conventional drugs-which are usually more aggressive than natural compounds-with polyphenols offers very valuable advantages such as the building of more efficient anticancer therapies with l

Objectives: This work investigated the effect of bacterial nanocellulose (BNC) alone or with chemisorbed chlorhexidine or povidone-iodine on post-tooth extraction repair in rats undergoing bisphosphonate therapy. Methods: Forty Wistar rats were treated with zoledronic acid, subjected to tooth extractions and allocated into groups according to the material inserted in the post-extraction socket: (1) BNC (n = 10); (2) BNC/Iodine (n = 10); (3) BNC/Chlorhex (n = 10); (4) Control (n = 10). Maxillae were dissected and macro- and microscopically analyzed. Results: Oral lesion frequency on macroscopic

Структура и состав микробных сообществ в водной толще Южного залива Мексики и обнаружение предполагаемых микроорганизмов, деградирующих углеводороды.

В ходе этого исследования была проведена оценка сообщества бактериопланктонов и его связи с экологическими переменными, включая общую концентрацию нефтяных углеводородов (ТПГ), в районе шельфа Юкатан в Южном заливе Мексики. Анализ разнообразия бета на основе последовательности 16S rRNA показал различия в структуре общины бактериопланктона между участками отбора проб. ПЕРМАНОВА указала, что эти изменения могут быть связаны главным образом с глубокими изменениями (см.5 в адрес 180 m), концентрация растворенного кислорода (2.06 в адрес 5.93 мг L-1), и концентрация хлорофилла (0.184 в адрес 7.65 м
