Computational proteomics to enhance personalized treatment of COVID-19 and Long COVID.

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to significant global health burden, including both acute infections and persistent post-acute sequelae, also known as Long COVID (LC) in survivors. While clinical management has reduced case-fatality rates, a substantial proportion of patients develop LC, a heterogeneous syndrome with long-term symptoms. This complex continuum requires therapeutic strategies for both the acute and chronic phases. Plasma proteomics has emerged as a powerful tool in precision medicin

Nutritional approaches in combating therapeutic resistance and enhancing treatment efficacy in cancer: the impact of ketogenic diets.

Cancer remains a major global health challenge, with therapeutic resistance significantly limiting treatment success. Traditional approaches, including surgery, chemotherapy, and radiotherapy, often encounter barriers such as metastasis and adverse effects on healthy tissues. The Warburg effect, which describes cancer cells’ reliance on glucose fermentation despite oxygen availability, has prompted investigations into alternative metabolic interventions. The ketogenic diet (KD), characterized by high fat intake and low carbohydrate intake, induces a metabolic shift that may selectively disadva

N-3 Long-Chain Polyunsaturated Fatty Acids, Eicosapentaenoic and Docosahexaenoic Acid, and the Role of Supplementation during Cancer Treatment: A Scoping Review of Current Clinical Evidence.

This scoping review examines the evidence for n-3 long-chain polyunsaturated fatty acid [LCPUFA, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] supplementation in clinical cancer therapy. A comprehensive literature search was performed to identify relevant clinical intervention studies conducted through August 2020. Fifty-seven unique cancer trials, assessing EPA and/or DHA supplementation pre- or post-treatment, concomitant with neoadjuvant chemotherapy, radiation or surgery, or in palliative therapy were included. Breast, head and neck, gastrointestinal, gastric, colorectal/rect

Harnessing the Therapeutic Potential of Mesenchymal Stem Cells in Cancer Treatment.

Cancer, as a complicated disease, is considered to be one of the major leading causes of death globally. Although various cancer therapeutic strategies have been established, however, some issues confine the efficacies of the treatments. In recent decades researchers for finding efficient therapeutic solutions have extensively focused on the abilities of stem cells in cancer inhibition. Mesenchymal stem cells (MSCs) are multipotent stromal cells that can the most widely extracted from various sources such as the bone marrow (BM), placenta, umbilical cord (UC), menses blood, Wharton's jelly (WJ

Resveratrol: Molecular Mechanisms, Health Benefits, and Potential Adverse Effects.

Resveratrol (RES), a naturally occurring polyphenolic compound, has garnered significant attention due to its diverse biological activities, which include anti-inflammatory, antioxidant, and antiaging properties. This review synthesizes current evidence concerning the molecular mechanisms, therapeutic efficacy, and safety profile of RES across a variety of pathologies, with an emphasis on the latest research conducted in recent years. Mechanistically, RES is known to modulate critical signaling pathways such as the activation of sirtuin 1. These actions collectively contribute to the attenuati

Adiponectin signalling in bone homeostasis, with age and in disease.

Adiponectin is the most abundant circulating adipokine and is primarily involved in glucose metabolism and insulin resistance. Within the bone, osteoblasts and osteoclasts express the adiponectin receptors, however, there are conflicting reports on the effects of adiponectin on bone formation and turnover. Many studies have shown a pro-osteogenic role for adiponectin in in vivo murine models and in vitro: with increased osteoblast differentiation and activity, alongside lower levels of osteoclastogenesis. However, human studies often demonstrate an inverse relationship between adiponectin conc

Targeting the two-pore channel 2 in cancer progression and metastasis.

The importance of Ca2+ signaling, and particularly Ca2+ channels, in key events of cancer cell function such as proliferation, metastasis, autophagy and angiogenesis, has recently begun to be appreciated. Of particular note are two-pore channels (TPCs), a group of recently identified Ca2+-channels, located within the endolysosomal system. TPC2 has recently emerged as an intracellular ion channel of significant pathophysiological relevance, specifically in cancer, and interest in its role as an anti-cancer drug target has begun to be explored. Herein, an overview of the cancer-related functions

The role of miR-320a and IL-1β in human chondrocyte degradation.

ObjectivesThis study aimed to explore the role of miR-320a in the pathogenesis of osteoarthritis (OA).MethodsHuman cartilage cells (C28/I2) were transfected with miR-320a or antisense oligonucleotides (ASO)-miR-320a, and treated with IL-1β. Subsequently the expression of collagen type II alpha 1 (Col2α1) and aggrecan (ACAN), and the concentrations of sulfated glycosaminoglycans (sGAG) and matrix metallopeptidase 13 (MMP-13), were assessed. Luciferase reporter assay, qRT-PCR, and Western blot were performed to explore whether pre-B-cell leukemia Homeobox 3 (PBX3) was a target of miR-320a. Furth

Salmonella enterica and outer membrane vesicles are current and future options for cancer treatment.

Conventional cancer therapies have many limitations. In the last decade, it has been suggested that bacteria-mediated immunotherapy may circumvent the restrictions of traditional treatments. For example, Salmonella enterica is the most promising bacteria for treating cancer due to its intrinsic abilities, such as killing tumor cells, targeting, penetrating, and proliferating into the tumor. S. enterica has been genetically modified to ensure safety and increase its intrinsic antitumor efficacy. This bacterium has been used as a vector for delivering anticancer agents and as a combination thera

[Immunotherapy - The New Era of Oncology].

In the field of immunotherapy, essential progress was achieved over the past years partially demonstrating long lasting therapeutic responses in different tumor entities. A better understanding of the interactions between the tumor and the immune system as well as the integration of immunotherapeutic approaches into clinical routine were the foundations for this development. The different approaches intervene on multiple levels of the immune response and directly or indirectly mount the patient's own immune defense against tumor cells. Immunotherapeutic approaches are represented by cytokine t

Understanding the Progression of Bone Metastases to Identify Novel Therapeutic Targets.

Bone is one of the most preferential target site for cancer metastases, particularly for prostate, breast, kidney, lung and thyroid primary tumours. Indeed, numerous chemical signals and growth factors produced by the bone microenvironment constitute factors promoting cancer cell invasion and aggression. After reviewing the different theories proposed to provide mechanism for metastatic progression, we report on the gene expression profile of bone-seeking cancer cells. We also discuss the cross-talk between the bone microenvironment and invading cells, which impacts on the tumour actions on su

Криопрезентация против пересадки свежих стволовых клеток в автоматической трансплантации для множественной миеломы: воздействие на раннюю токсичность и пересадку.

ВВЕДЕНИЕ: Аутологическая трансплантация стволовых клеток (ASCT) по-прежнему является краеугольным камнем терапии для имеющих на это право пациентов с множественной миеломой. Криопирование гематополиетических трансплантаций обеспечивает логистическую гибкость, но может способствовать повышению токсичности, связанной с процедурой, и использованию ресурсов. Мы провели two- Фаза, неслучайное двухнациональное исследование в высших центрах Сантьяго, Чили, и Севилье, Испания, сравнивая криопрезентированные и некриопретрофированные трансплантаты у пациентов, проходящих ACCT.

Circulating biosignatures in multiple myeloma and their role in multidrug resistance.

A major obstacle to chemotherapeutic success in cancer treatment is the development of drug resistance. This occurs when a tumour fails to reduce in size after treatment or when there is clinical relapse after an initial positive response to treatment. A unique and serious type of resistance is multidrug resistance (MDR). MDR causes the simultaneous cross resistance to unrelated drugs used in chemotherapy. MDR can be acquired through genetic alterations following drug exposure, or as discovered by us, through alternative pathways mediated by the transfer of functional MDR proteins and nucleic

Chemokines: humble yet mighty players in the tumour microenvironment.

Chemokines are tiny chemotactic cytokines which play a crucial role in pathophysiology by maintaining homeostasis and inflammation. Their role in the tumour microenvironment is very much puzzling because of both pro- and anti-tumourigenic effects. Chemokines have gained much attention today, since it has been recognized that they are game changers in the TME via controlling immune cell recruitment, angiogenesis, metastasis, tumour growth and drug resistance. In this review, we are exploring the role of several chemokines and their receptors in the TME with special focus on immune cell recruitm

Bridging the Gap in Understanding Bone Metastasis: A Multifaceted Perspective.

The treatment of patients with advanced cancer poses clinical problems due to the complications that arise as the disease progresses. Bone metastases are a common problem that cancer patients may face, and currently, there are no effective drugs to treat these individuals. Prostate, breast, and lung cancers often spread to the bone, causing significant and disabling health conditions. The bone is a highly active and dynamic tissue and is considered a favorable environment for the growth of cancer. The role of osteoblasts and osteoclasts in the process of bone remodeling and the way in which th

Targeting NETosis: nature's alarm system in cancer progression.

Neutrophils are recognized active participants in inflammatory responses and are intricately linked to cancer progression. In response to inflammatory stimuli, neutrophils become activated, releasing neutrophils extracellular traps (NETs) for the capture and eradication of pathogens, a phenomenon termed NETosis. With a deeper understanding of NETs, there is growing evidence supporting their role in cancer progression and their involvement in conferring resistance to various cancer therapies, especially concerning tumor reactions to chemotherapy, radiation therapy (RT), and immunotherapy. This

Cytokine-Engineered Chimeric Antigen Receptor-T Cell Therapy: How to Balance the Efficacy and Toxicity.

Chimeric antigen receptor (CAR)-T cell immunotherapy has revolutionized the paradigm in hematological malignancies. However, its efficacy in treating solid tumors remains limited because the immunosuppressive tumor microenvironment (ITME) seriously blocks T cell activation, infiltration, and proliferation. Cytokines, driving potent assisted function by enhanced T cell expansion, persistence, and direct tumor cell killing, have long been acknowledged as promising candidates combined with CAR-T cells to improve treatment outcomes. Despite their preclinical success, significant toxicity occurs in

Ассоциированные клетки B в аутоиммунных болезнях: патогенез и клинические последствия.

Будучи разнородным подмножеством клеток В, связанные с возрастом клетки В (ABC) имеют различные транскрипционные профили, процессы экстрафолликулярной дифференциации и множественные функции в автоматическом иммунитете. Сигналы TLR7 и TLR9 наряду с стимуляцией IFN-__ и IL-21 имеют важное значение для дифференциации ABC, которая также регулируется хемокиновыми рецепторами, включая CXCR3 и CCR2, и интегралами, включая CD11b и CD11c. С учетом их функций, связанных с поглощением и представлением антигенов, секрецией цитокина, а также активацией ячеек Т, ABC демонстрируют потенциал в прогнозе, диагн

Histone deacetylase upregulation of neuropilin-1 in osteosarcoma is essential for pulmonary metastasis.

The lungs represent the most common site of metastasis for osteosarcoma (OS). Despite our advances in developing targeted therapies for treating solid malignancies, broad acting chemotherapies remain the first line treatment for OS. In assaying the efficacy of approved therapeutics for non-OS malignancies, we previously identified the histone deacetylase 1 and 2 (HDAC1 and 2) inhibitor, romidepsin, as effective for the treatment of established lung metastatic OS. Yet, romidepsin has noted toxicities in humans and so here we aimed to define the primary mechanisms through which HDAC1/2 mediate O
