Special Issue Information

Dear Colleagues,

According to the World Health Organization (WHO)’s latest estimates, in 2022, there were 20 million new cancer diagnoses and 9.7 million cancer deaths globally. The therapeutic strategy against cancer depends on several factors, including the type and stage of cancer, a patient’s general health status and their tolerance to chemotherapy treatment (if needed). In fact, adverse drug reactions often force doctor’s to reduce the dose of treatment. As a consequence, patients risk being undertreated, resulting in worsen oncologic outcomes. Phytochemicals (as well phenolics, flavonoids, and carotenoids) are dietary bioactive compounds present in fruits and vegetables known to act, under certain conditions, as pro-oxidant and cytotoxic agents in certain tissues, including tumour cells. Due to their properties, dietary phytochemicals are used to supplement conventional chemotherapy drugs to increase anti-tumor efficacy, or they can be modified to synthesize novel anti-cancer formulations less cytotoxic to normal tissue cells and more effective against cancer. In this Special Issue, we invite authors to submit original research and review articles investigating different metabolic changes in cancer cells due to the administration of natural compounds and their derivatives. Also, we gratefully appreciate all contributions focused on the identification of new therapeutic approaches using vegetable bioactive compounds in patients for improving positive outcomes in cancer treatment.

Current therapies for colorectal cancer (CRC) are associated with significant side effects and limitations, driving the search for novel therapeutic approaches. This study investigated the antiproliferative potential of D-limonene, a natural compound, on human colorectal adenocarcinoma (Caco-2) cells and analyzed its underlying mechanisms. Caco-2 cells were treated with D-limonene or doxorubicin (DOX) for 24 h. Cell viability was assessed using the MTT assay, with D-limonene and DOX showing IC50 values of 18.6 and 6.4 µM, respectively. In comparison to controls, D-limonene treatment dramatically enhanced the formation of reactive oxygen species (ROS) and decreased cellular antioxidant capacity, as seen by concentration-dependent lower glutathione (GSH) levels. The substance also increased the levels of pro-apoptotic proteins (caspase-3, Bax), tumor suppressor p53, lactate dehydrogenase (LDH), and inflammatory indicators [tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1β)]. Furthermore, in a concentration-dependent way, D-limonene therapy decreased the levels of matrix metalloproteinases (MMP2, MMP9), proliferation marker Ki67, and the anti-apoptotic protein Bcl-2. These results imply that the induction of oxidative stress, inflammation, and apoptotic pathways mediates D-limonene’s antiproliferative actions in colon cancer cells. Our findings show that D-limonene has therapeutic promise as a natural substitute for the treatment of colorectal cancer. Full article

Breast cancer remains a leading global cause of cancer-related mortality among women, requiring the development of safer and more effective therapeutic strategies. Herbal medicines have gained increasing attention as complementary approaches due to their multi-targeted actions, more limited toxicities, and the potential ability to overcome resistance associated with conventional treatments. This review highlights the antitumor properties and underlying mechanisms of several well-studied herbal compounds, including curcumin, resveratrol, epigallocatechin gallate, withaferin A, thymoquinone, baicalin, berberine, Oldenlandia diffusa, and Salvia miltiorrhiza. These phytochemicals exert antitumor effects by inducing apoptosis, inhibiting cell proliferation and metastasis, modulating immune responses, and sensitizing tumor cells to chemotherapy and radiotherapy. Furthermore, many of these agents regulate key signaling pathways, such as nuclear factor kappa-light-chain-enhancer of activated B cells, phosphatidylinositol 3-kinase/AKT, p53, signal transducer and activator of transcription 3, and extracellular signal-regulated kinases 1/2, and the tumor microenvironment. Despite promising preclinical and early clinical evidence, challenges remain regarding the bioavailability, standardization, and large-scale clinical validation of these phytochemicals. This review underscores the therapeutic potential of herbal medicines in breast cancer treatment and advocates for further research to facilitate their integration into evidence-based oncology practice.

Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory condition that may progress to colorectal cancer (CRC), presenting significant challenges to global health. With shifts in lifestyle, the incidence of both conditions continues to rise, underscoring the urgent need for effective treatments. While traditional therapies can be effective, their high recurrence rates and associated adverse reactions limit their broader application. Luteolin, a flavonoid derived from natural plants, has emerged as a promising focus in both IBD and CRC research due to its multi-target therapeutic potential. This article reviews the molecular mechanisms and signaling pathways through which luteolin regulates immune cell differentiation, mitigates inflammation and oxidative stress, modulates gut microbiota, and restores intestinal mucosal barrier function in IBD. In the context of CRC, luteolin demonstrates significant anti-tumor effects by inhibiting cancer cell proliferation, inducing apoptosis, and suppressing cell migration and invasion. Notably, luteolin has demonstrated significant improvements in IBD symptoms by influencing the differentiation of T cell subsets, decreasing the expression of inflammatory mediators, activating antioxidant pathways, and enhancing the structure of gut microbiota. Furthermore, advancements in formulation technology, such as the use of polymer micelles and responsive nanoparticles, have greatly improved the bioavailability and efficacy of luteolin. However, further investigation is needed to address the bioavailability and potential toxicity of luteolin, particularly in the critical transition from IBD to CRC. This article emphasizes the potential of luteolin in the treatment of IBD and CRC and anticipates its promising prospects for future clinical applications as a natural therapeutic agent. Full article
