Reactive oxygen species (ROS) in cancer: from mechanism to therapeutic implications.

Reactive oxygen species (ROS) act as critical secondary messengers in various intracellular signaling pathways that regulate cellular proliferation, differentiation, and survival under normal physiological conditions. However, dysregulation of redox signaling-driven by genetic mutations, epigenetic alterations, and posttranscriptional or posttranslational modifications-plays a central role in malignant transformation and cancer progression. Cancer cells typically exhibit elevated basal ROS levels due to increased metabolic activity, mitochondrial dysfunction, and oncogene activation. This mode

Orthogonal targeting of osteoclasts and myeloma cells for radionuclide stimulated dynamic therapy induces multidimensional cell death pathways.

Rationale: Multiple myeloma (MM) is a multifocal malignancy of bone marrow plasma cells, characterized by vicious cycles of remission and relapse that eventually culminate in death. The disease remains mostly incurable largely due to the complex interactions between the bone microenvironment (BME) and MM cells (MMC). In the "vicious cycle" of bone disease, abnormal activation of osteoclasts (OCs) by MMC causes severe osteolysis, promotes immune evasion, and stimulates the growth of MMC. Disrupting these cancer-stroma interactions would enhance treatment response. Methods: To disrupt this cycle

Multifunctionality of Calebin A in inflammation, chronic diseases and cancer.

Chronic diseases including cancer have high case numbers as well as mortality rates. The efficient treatment of chronic diseases is a major ongoing medical challenge worldwide, because of their complexity and many inflammatory pathways such as JNK, p38/MAPK, MEK/ERK, JAK/STAT3, PI3K and NF-κB among others being implicated in their pathogenesis. Together with the versatility of chronic disease classical mono-target therapies are often insufficient. Therefore, the anti-inflammatory as well as anti-cancer capacities of polyphenols are currently investigated to complement and improve the effect of

The Role of Plant-Derived Natural Products as a Regulator of the Tyrosine Kinase Pathway in the Management of Lung Cancer.

One of the most common malignant tumors worldwide is lung cancer, and it is associated with the highest death rate among all cancers. Traditional treatment options for lung cancer include radiation, chemotherapy, targeted therapy, and surgical resection. However, the survival rate is low, and the outlook is still dreadfully dire. The pursuit of a paradigm change in treatment approaches is, therefore, imperative. Tyrosine kinases (TKs), a subclass of protein kinases, regulate vital cellular function by phosphorylating tyrosine residues in proteins. Mutations, overexpression, and autocrine parac

Fatty acid synthase in chemoresistance: mechanisms and therapeutic opportunities.

Chemoresistance has been a major obstacle to the efficient treatment of cancer. Recently, targeting lipid metabolism has gained significant attention because of its roles not only in promoting cancer progression but also in inducing chemotherapy resistance. Fatty acid synthase (FAS) is the sole enzyme that is in charge of catalyzing the synthesis of palmitate, a long-chain lipid that is essential for membrane construction and post-translational modification in cell biology. Both FAS and its product, palmitate, have been validated as critical players in mediating or causing chemoresistance in c

Emerging and underexplored ginsenosides in cancer therapy (2020-2025): Beyond cytotoxic mechanisms.

Ginsenosides from Panax plants have long been studied as potential anticancer agents. In earlier years, most research focused on a few well-known ginsenosides that showed strong direct cytotoxicity, such as Rg3 and Rh2. As a result, many other ginsenosides were considered less active and received limited attention. However, studies published between 2020 and 2025 indicate that several previously underexplored ginsenosides also exhibit meaningful anticancer activity. These compounds often do not function as strongly cytotoxic agents. Instead, they act through broader and more indirect mechanism
