Natural bioactive molecules and chemotherapeutics synergism for enhanced cancer therapy.

BACKGROUND: Chemotherapy remains a foundation of cancer care but is limited by multidrug resistance, systemic toxicities, and suboptimal selectivity, prompting interest in adjunctive strategies that improve efficacy and tolerability without adding significant burden to patients or healthcare systems. AIMS/OBJECTIVES: This review highlights evidence on natural bioactive compounds, including polyphenols, alkaloids, terpenoids, and fungal metabolites, as adjuvants to standard chemotherapeutics, with objectives to: first, delineate mechanisms by which these agents enhance cytotoxic efficacy and o

Biologics for bone regeneration: advances in cell, protein, gene, and mRNA therapies.

Bone fractures represent a significant global healthcare burden. Although fractures typically heal on their own, some fail to regenerate properly, leading to nonunion, a condition that causes prolonged disability, morbidity, and mortality. The challenge of treating nonunion fractures is further complicated in patients with underlying bone disorders where systemic and local factors impair bone healing. Traditional treatment approaches, including autografts, allografts, xenografts, and synthetic biomaterials, face limitations such as donor site pain, immune rejection, and insufficient mechanical

Biobehavioral Pathways and Cancer Progression: Insights for Improving Well-Being and Cancer Outcomes.

The relationship between psychosocial factors and cancer has intrigued people for centuries. In the last several decades there has been an expansion of mechanistic research that has revealed insights regarding how stress activates neuroendocrine stress-response systems to impact cancer progression. Here, we review emerging mechanistic findings on key pathways implicated in the effect of stress on cancer progression, including the cellular immune response, inflammation, angiogenesis, and metastasis, with a primary focus on the mediating role of the sympathetic nervous system. We discuss converg

Small molecule inhibitors targeting the cancers.

Compared with traditional therapies, targeted therapy has merits in selectivity, efficacy, and tolerability. Small molecule inhibitors are one of the primary targeted therapies for cancer. Due to their advantages in a wide range of targets, convenient medication, and the ability to penetrate into the central nervous system, many efforts have been devoted to developing more small molecule inhibitors. To date, 88 small molecule inhibitors have been approved by the United States Food and Drug Administration to treat cancers. Despite remarkable progress, small molecule inhibitors in cancer treatme

RHOA at the intersection of inflammation-driven and sporadic colorectal cancer.

In the last decades, colorectal cancer (CRC) has emerged as a global problem, representing approximately 10% of all malignant tumors and the second leading cause of cancer-related death. Colitis-associated cancer (CAC) arises from chronic unresolved inflammation and is typically characterised by poor prognosis. Among key cellular regulators, the small GTPase RHOA controls cytoskeleton dynamics in various cell types and, thereby, key biological processes. Although it has been linked to various diseases, the role of RHOA in cancer remains controversial. RHOA has been proposed as a biomarker in c

Протеазомное ингибирование подрывает микроваскулярную целостность, оказывая заметное воздействие на неиммунные эндотелиальные клетки и иммунные клетки.

Для нескольких миеломы (ММ) установлены хемапаутические протеасомные ингибиторы Бортезомиб (БЗ, обратимый ингибитор) и Карфилзомиб (КФЗ, необратимый ингибитор). Вместе с тем, их целевые и нецелевые эффекты, связанные с прохожими в крови, точно не известны. Чтобы прояснить острое негативное воздействие внутривенного протеасомального ингибитора, мы изучили некоторые из ключевых типов микроваскулатуры крови: барьер эндотелиальные клетки, периферийные моноядерно-кротовые клетки крови и множественные клетки миеломы (MM1.S).

Nanoparticles Based Therapeutic Approaches in Oncogenic Viral Infections: A Review.

Nanotechnology has revolutionized biomedical research by providing novel strategies for the prevention, diagnosis, and treatment of oncogenic viral infections. Nanoparticles, possessing tunable physicochemical properties, enable targeted drug delivery, enhance vaccine efficacy, and facilitate advanced viral diagnostics, addressing key limitations of conventional therapies. Oncogenic viruses contribute substantially to the global burden of cancer through persistent infections and are influenced by environmental and lifestyle factors. The objective of this review is to synthesize and critically

Beyond boundaries: unraveling innovative approaches to combat bone-metastatic cancers.

Evidence demonstrated that bones, liver, and lungs are the most common metastasis sites in some human malignancies, especially in prostate and breast cancers. Bone is the third most frequent target for spreading tumor cells among these organs and tissues. Patients with bone-metastatic cancers face a grim prognosis characterized by short median survival time. Current treatments have proven insufficient, as they can only inhibit metastasis or tumor progression within the bone tissues rather than providing a curative solution. Gaining a more profound comprehension of the interplay between tumor c

STAT3 pathway in cancers: Past, present, and future.

Signal transducer and activator of transcription 3 (STAT3), a member of the STAT family, discovered in the cytoplasm of almost all types of mammalian cells, plays a significant role in biological functions. The duration of STAT3 activation in normal tissues is a transient event and is strictly regulated. However, in cancer tissues, STAT3 is activated in an aberrant manner and is induced by certain cytokines. The continuous activation of STAT3 regulates the expression of downstream proteins associated with the formation, progression, and metastasis of cancers. Thus, elucidating the mechanisms o

Targeting Abnormal Hematopoietic Stem Cells in Chronic Myeloid Leukemia and Philadelphia Chromosome-Negative Classical Myeloproliferative Neoplasms.

Myeloproliferative neoplasms (MPNs) are unique hematopoietic stem cell disorders sharing mutations that constitutively activate the signal-transduction pathways involved in haematopoiesis. They are characterized by stem cell-derived clonal myeloproliferation. The key MPNs comprise chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). CML is defined by the presence of the Philadelphia (Ph) chromosome and BCR-ABL1 fusion gene. Despite effective cytoreductive agents and targeted therapy, complete CML/MPN stem cell eradication is r

Small molecules in targeted cancer therapy: advances, challenges, and future perspectives.

Due to the advantages in efficacy and safety compared with traditional chemotherapy drugs, targeted therapeutic drugs have become mainstream cancer treatments. Since the first tyrosine kinase inhibitor imatinib was approved to enter the market by the US Food and Drug Administration (FDA) in 2001, an increasing number of small-molecule targeted drugs have been developed for the treatment of malignancies. By December 2020, 89 small-molecule targeted antitumor drugs have been approved by the US FDA and the National Medical Products Administration (NMPA) of China. Despite great progress, small-mol

A Systematic Review of Glioblastoma-Targeted Therapies in Phases II, III, IV Clinical Trials.

Glioblastoma (GBM), the most frequent and aggressive glial tumor, is currently treated as first line by the Stupp protocol, which combines, after surgery, radiotherapy and chemotherapy. For recurrent GBM, in absence of standard treatment or available clinical trials, various protocols including cytotoxic drugs and/or bevacizumab are currently applied. Despite these heavy treatments, the mean overall survival of patients is under 18 months. Many clinical studies are underway. Based on clinicaltrials.org and conducted up to 1 April 2020, this review lists, not only main, but all targeted therapi

Navigating the Landscape of Exosomal microRNAs: Charting Their Pivotal Role as Biomarkers in Hematological Malignancies.

Under physiological and pathological conditions, all cells release extracellular vesicles named exosomes, which act as transporters of lipidic, protein, and genetic material from parent to recipient cells. Neoplastic cells can secrete higher number of exosomes to exert pro-tumoral effects such as microenvironmental changes, disease progression, immunosuppression and drug-resistance. This holds true for both organ-specific cancers and hematologic malignancies. One of the most important components of exosomal cargo are microRNAs which can mediate all the abovementioned effects. More specifically
