Anticancer natural products from the Middle East and North Africa: biodiversity, mechanisms, and translational challenges.

Cancer remains one of the leading causes of morbidity and mortality worldwide, imposing substantial clinical, societal, and economic burdens. Despite major advances in surgical oncology, systemic chemotherapy, radiation therapy, molecularly targeted therapeutics, and immune checkpoint inhibition, contemporary cancer treatment remains constrained by dose-limiting toxicities, intratumoral and intertumoral heterogeneity, and the inexorable emergence of multifaceted drug resistance mechanisms. These persistent therapeutic challenges have reinstated interest in natural products (NPs) as evolutionar

The crosstalk between non-coding RNAs and oxidative stress in cancer progression.

As living standards elevate, cancers are appearing in growing numbers among younger individuals globally and these risks escalate with advancing years. One of the reasons is that instability in the cancer genome reduces the effectiveness of conventional drug treatments and chemotherapy, compared with more targeted therapies. Previous research has discovered non-coding RNAs' crucial role in shaping genetic networks involved in cancer cell growth and invasion through their influence on messenger RNA production or protein binding. Additionally, the interaction between non-coding RNAs and oxidativ

The roles of Cryptochrome-1: the circadian clock as a control point in cancer therapy.

In this review, we carefully describe the composition and operation of cryptochrome-1 (CRY1). We introduce four related signaling pathways, namely cAMP/PKA/CREB signaling way, HIFα signaling way, NF-κB signaling way, STAT3 signaling way, FOXO signaling pathway and Hedgehog (HH) signaling pathway. We also emphasize the current understanding of the complex roles CRY1 plays in the progression of various solid tumors. We propose that its function represents a novel therapeutic target that could pave the way for new cancer treatments. Additionally, we summarize three emerging therapeutic strategies

Semaglutide: a key medication for managing cardiovascular-kidney-metabolic syndrome.

Recent trials underscore the cardiovascular (CV), renal, and metabolic benefits of semaglutide in individuals with and without type 2 diabetes (T2D). In T2D, semaglutide enhances glycemic control, reduces major adverse CV events (MACE), and slows chronic kidney disease (CKD) progression. The SUSTAIN-6 trial demonstrated a 26% MACE reduction (HR 0.74; 95% CI: 0.58-0.95; p = 0.02) in high CV-risk patients with T2D using semaglutide (0.5 or 1.0 mg weekly). Similarly, the FLOW trial showed a 24% reduction in major kidney disease events (HR 0.76; 95% CI: 0.66-0.88; p = 0.002) with weekly 1.0 mg sem

The important role of the histone acetyltransferases p300/CBP in cancer and the promising anticancer effects of p300/CBP inhibitors.

Histone acetyltransferases p300 (E1A-associated protein p300) and CBP (CREB binding protein), collectively known as p300/CBP due to shared sequence and functional synergy, catalyze histone H3K27 acetylation and consequently induce gene transcription. p300/CBP over-expression or over-activity activates the transcription of oncogenes, leading to cancer cell growth, resistance to apoptosis, tumor initiation and development. The discovery of small molecule inhibitors targeting p300/CBP histone acetyltransferase activity, bromodomains, dual inhibitors of p300/CBP and BRD4 bromodomains, as well as p

Understanding Autoimmunity: Mechanisms, Predisposing Factors, and Cytokine Therapies.

Autoimmunity refers to an organism's immune response against its own healthy cells, tissues, or components, potentially leading to irreversible damage to vital organs. Central and peripheral tolerance mechanisms play crucial roles in preventing autoimmunity by eliminating self-reactive T and B cells. The disruption of immunological tolerance, characterized by the failure of these mechanisms, results in the aberrant activation of autoreactive lymphocytes that target self-tissues, culminating in the pathogenesis of autoimmune disorders. Genetic predispositions, environmental exposures, and immun

Application of toll-like receptors (TLRs) and their agonists in cancer vaccines and immunotherapy.

Toll-like receptors (TLRs) are pattern recognition receptors (PRRs) expressed in various immune cell types and perform multiple purposes and duties involved in the induction of innate and adaptive immunity. Their capability to propagate immunity makes them attractive targets for the expansion of numerous immunotherapeutic approaches targeting cancer. These immunotherapeutic strategies include using TLR ligands/agonists as monotherapy or combined therapeutic strategies. Several TLR agonists have demonstrated significant efficacy in advanced clinical trials. In recent years, multiple reports est

Therapeutic Vaccination in Head and Neck Squamous Cell Carcinoma-A Review.

Therapeutic vaccination is one of the most effective immunotherapeutic approaches, second only to immune checkpoint inhibitors (ICIs), which have already been approved for clinical use. Head and neck squamous cell carcinomas (HNSCCs) are heterogenous epithelial tumors of the upper aerodigestive tract, and a significant proportion of these tumors tend to exhibit unfavorable therapeutic responses to the existing treatment options. Comprehending the immunopathology of these tumors and choosing an appropriate immunotherapeutic maneuver seems to be a promising avenue for solving this problem. The c

Theranostic Potentials of Gold Nanomaterials in Hematological Malignancies.

Hematological malignancies (HMs) are a heterogeneous group of blood neoplasia generally characterized by abnormal blood-cell production. Detection of HMs-specific molecular biomarkers (e.g., surface antigens, nucleic acid, and proteomic biomarkers) is crucial in determining clinical states and monitoring disease progression. Early diagnosis of HMs, followed by an effective treatment, can remarkably extend overall survival of patients. However, traditional and advanced HMs' diagnostic strategies still lack selectivity and sensitivity. More importantly, commercially available chemotherapeutic dr

Cannabidiol on the Path from the Lab to the Cancer Patient: Opportunities and Challenges.

Cannabidiol (CBD), a major non-psychotropic component of cannabis, is receiving growing attention as a potential anticancer agent. CBD suppresses the development of cancer in both in vitro (cancer cell culture) and in vivo (xenografts in immunodeficient mice) models. For critical evaluation of the advances of CBD on its path from laboratory research to practical application, in this review, we wish to call the attention of scientists and clinicians to the following issues: (a) the biological effects of CBD in cancer and healthy cells; (b) the anticancer effects of CBD in animal models and clin

The Role of Diet in Prognosis among Cancer Survivors: A Systematic Review and Meta-Analysis of Dietary Patterns and Diet Interventions.

Cancer survival continues to improve in high-income countries, partly explained by advances in screening and treatment. Previous studies have mainly examined the relationship between individual dietary components and cancer prognosis in tumours with good therapeutic response (breast, colon and prostate cancers). The aim of this review is to assess qualitatively (and quantitatively where appropriate) the associations of dietary patterns and cancer prognosis from published prospective cohort studies, as well as the effect of diet interventions by means of randomised controlled trials (RCT). A sy

Close interactions between lncRNAs, lipid metabolism and ferroptosis in cancer.

Abnormal lipid metabolism including synthesis, uptake, modification, degradation and transport has been considered a hallmark of malignant tumors and contributes to the supply of substances and energy for rapid cell growth. Meanwhile, abnormal lipid metabolism is also associated with lipid peroxidation, which plays an important role in a newly discovered type of regulated cell death termed ferroptosis. Long noncoding RNAs (lncRNAs) have been proven to be associated with the occurrence and progression of cancer. Growing evidence indicates that lncRNAs are key regulators of abnormal lipid metabo

A guide to cancer immunotherapy: from T cell basic science to clinical practice.

The T lymphocyte, especially its capacity for antigen-directed cytotoxicity, has become a central focus for engaging the immune system in the fight against cancer. Basic science discoveries elucidating the molecular and cellular biology of the T cell have led to new strategies in this fight, including checkpoint blockade, adoptive cellular therapy and cancer vaccinology. This area of immunological research has been highly active for the past 50 years and is now enjoying unprecedented bench-to-bedside clinical success. Here, we provide a comprehensive historical and biological perspective regar

Transcription and Translation Inhibitors in Cancer Treatment.

Transcription and translation are fundamental cellular processes that govern the protein production of cells. These processes are generally up regulated in cancer cells, to maintain the enhanced metabolism and proliferative state of these cells. As such cancerous cells can be susceptible to transcription and translation inhibitors. There are numerous druggable proteins involved in transcription and translation which make lucrative targets for cancer drug development. In addition to proteins, recent years have shown that the "undruggable" transcription factors and RNA molecules can also be targ

Endoplasmic reticulum stress in disease pathogenesis: its implications for therapy.

Endoplasmic reticulum (ER) stress is a key cellular mechanism that is important in the development of many diseases, including cancer. Since the discovery of the unfolded protein response (UPR), research has greatly improved our understanding of how ER stress affects cellular functions, especially protein folding and adaptation to stress. The UPR consists of three main branches: IRE1, ATF6, and PERK, each of which is crucial for regulating stress responses, protein homeostasis, and apoptosis. These pathways normally help cells handle stress effectively; however, excessive or prolonged activati
