Cardiovascular disease (CVD) remains the primary cause of global morbidity and mortality. CVD includes various life-threatening conditions such as myocardial infarction, stroke and peripheral arterial diseases. In this context, atherosclerosis continues to play the principal role in the pathogenesis of these conditions. Atherosclerosis emanates from a set of modifiable and non-modifiable risk factors that include age, male gender, family history, obesity, smoking, diabetes mellitus and hypertension. Recent evidence classifies atherosclerosis as a latent disease affecting all-sized arteries with a predilection for arterial branching points of decreased or absent blood supply. Atherosclerosis is not only a lipid metabolism disorder, but is also a chronic inflammatory one. This review providesa synoptic discussion of the underlying pathological mechanisms of atherosclerosis andthe currently applied therapeutic interventions. We then discuss the classical lipid-lowering therapies as well as the newly discovered therapies. For the classical therapies, we point out the importance of statins and ezetimibe in reducing plasma cholesterol levels by virtue of their effects on synthesis, reuptake and intestinal absorption of cholesterol. We also discuss the role of fibrates in modulating lipid metabolism and improving the ratio of high-density to low-density density lipoproteins. This study focuseson the more recent molecular and genetic interventions exemplified by proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies, evinacumab, and microRNA inhibitors. Special attention is also given to clinical trials involving these therapies.

Pancreatic cancer (PC) is the fourth leading cause of all cancer-related deaths. Despite major improvements in treating PC, low survival rate remains a major challenge, indicating the need for alternative approaches, including herbal medicine. Among medicinal plants is Ziziphus nummularia (family Rhamnaceae), which is a thorny shrub rich in bioactive molecules. Leaves of Ziziphus nummularia have been used to treat many pathological conditions, including cancer. However, their effects on human PC are still unknown. Here, we show that the treatment of human pancreatic ductal adenocarcinoma cells (Capan-2) with Ziziphus nummularia ethanolic extract (ZNE) (100–300 μg/mL) attenuated cell proliferation in a time- and concentration-dependent manner. Pretreatment with N-acetylcysteine, an ROS scavenger, attenuated the anti-proliferative effect of ZNE. In addition, ZNE significantly decreased the migratory and invasive capacity of Capan-2 with a concomitant downregulation of integrin α2 and increased cell–cell aggregation. In addition, ZNE inhibited in ovo angiogenesis as well as reduced VEGF and nitric oxide levels. Furthermore, ZNE downregulated the ERK1/2 and NF-κB signaling pathways, which are known to drive tumorigenic and metastatic events. Taken together, our results suggest that ZNE can attenuate the malignant phenotype of Capan-2 by inhibiting hallmarks of PC. Our data also provide evidence for the potential anticancer effect of Ziziphus nummularia, which may represent a new resource of novel anticancer compounds, especially ones that can be utilized for the management of PC.

Herbal medicine has been gaining special interest as an alternative choice of treatment for several diseases, being generally accessible, cost-effective and safe, with fewer side-effects compared to chemically synthesized medicines. Over 25% of drugs worldwide are derived from plants, and surveys have shown that, when available, herbal medicine is the preferred choice of treatment. Origanum syriacum (Lamiaceae) is a widely used medicinal plant in the Middle East, both as a home and a folk remedy, and in the food and beverage industry. Origanum syriacum contains numerous phytochemical compounds, including flavonoids, phenols, essential oils, and many others. Because of its bioactive compounds, O. syriacum possesses antioxidant, antimicrobial, and antiparasitic capacities. In addition, it can be beneficial in the treatment of various diseases such as cancer, neurodegenerative disorders, and peptic ulcers. In this review, the chemical compositions of different types of extracts and essential oils from this herb will first be specified. Then, the pharmacological uses of these extracts and essential oils in various contexts and diseases will be discussed, putting emphasis on their efficacy and safety. Finally, the cellular and molecular mechanisms of O. syriacum phytochemicals in disease treatment will be described as a basis for further investigation into the plant’s pharmacological role.

Breast cancer is a common and chronic condition, and despite improvements in diagnosis, treatment, and prevention, the number of cases of breast cancer is rising annually. New therapeutic drugs that target specific checkpoints should be created to fight breast cancer. Mandragora autumnalis possesses substantial cultural value as a herb and is regarded as one of the most significant medicinal plants; however, little is known about its anticancerous biological activity and chemopreventive molecular pathways against the triple-negative breast cancer (MDA-MB-231) cell line. In this study, the antioxidant, anticancer, and underlying molecular mechanisms of the Mandragora autumnalis ethanolic leaves extract (MAE) were evaluated, and its phytochemical composition was determined. Results indicated that MAE diminished the viability of MDA-MB-231 cells in a concentration- and time-dependent manner. Although MAE exhibited 55% radical scavenging activity at higher concentrations in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, the attenuation of its cytotoxic effects in MDA-MB-231 cells with N-acetylcysteine (NAC) co-treatment suggests a potential role of oxidative stress. Additionally, MAE caused an increase in the tumor suppressor p53. Moreover, this extract caused a significant decrease in the expression of Ki-67 (a cellular proliferation marker), MMP-9 (matrix metalloproteinase-9, an enzyme involved in extracellular matrix degradation and metastasis), and STAT-3 (a transcription factor regulating cell growth and survival). Also, MAE altered cell cycle, cell migration, angiogenesis, invasion, aggregation, and adhesion to suppress cellular processes linked to metastasis. All of our research points to MAE’s potential to function as an anticancer agent and opens up new possibilities for the development of innovative triple-negative breast cancer treatments.

Background/Objectives: Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype associated with poor prognosis and limited targeted therapeutic options. Natural products, rich in bioactive phytochemicals, represent a potential source of novel anticancer agents. This study examined the phytochemical profile and anticancer activity of an ethanolic bulb extract of Cyclamen persicum (CPE), with a primary focus on TNBC. Methods: The phytochemical composition of CPE was analyzed by liquid chromatography–mass spectrometry (LC–MS). Antioxidant activity was evaluated using DPPH radical scavenging assay. The anticancer effects of CPE were assessed mainly in MDA-MB-231 TNBC cells using MTT cell viability assays, Ki-67 immunoblotting, Western blot analysis of signaling proteins, wound healing migration assays, Matrigel invasion assays, adhesion assays and cell–cell aggregation assays. Antiproliferative activity was also examined in 22RV1 (prostate), Capan-2 (pancreatic), and HCT116 (intestinal) cancer cell lines using MTT assays. Results: LC–MS analysis indicated that the extract contains multiple polyphenolic and organic acid constituents commonly associated with bioactivity. Consistent with this profile, CPE demonstrated strong antioxidant activity. In MDA-MB-231 cells, CPE significantly reduced cell viability and proliferation, accompanied by decreased Ki-67 expression. Treatment was associated with modulation of proteins involved in proliferative and survival signaling, induction of apoptosis-related markers, and reduced migratory and invasive capacities. CPE also promoted cell–cell homotypic aggregation, suggesting a shift toward a less aggressive phenotype. These effects were associated with reduced phosphorylation of p65, indicating possible modulation of NF-κB signaling. Additionally, CPE decreased proliferation in 22RV1, Capan-2, and HCT116 cancer cell lines. Conclusions: Collectively, these findings indicate that C. persicum bulb extract exerts multimodal anticancer effects in vitro, particularly in TNBC cells, and highlights its potential as a source of bioactive compounds warranting further mechanistic and translational investigation.
