Abstract
Breast cancer remains a leading cause of cancer-related mortality among women worldwide. One of its defining features is resistance to apoptosis, driven by aberrant expression of apoptosis-related proteins, notably the overexpression of anti-apoptotic Bcl-2 proteins. These proteins enable breast cancer cells to evade apoptosis and develop resistance to chemotherapy, underscoring their critical role as therapeutic targets. Diet plays a significant role in breast cancer risk, potentially escalating or inhibiting cancer development. Recognizing the limitations of current treatments, extensive research is focused on exploring bioactive compounds derived from natural sources such as plants, fruits, vegetables, and spices. These compounds are valued for their ability to exert potent anticancer effects with minimal toxicity and side effects. While literature extensively covers the effects of various dietary compounds in inducing apoptosis in cancer cells, comprehensive information specifically on how dietary bioactive compounds modulate anti-apoptotic Bcl-2 protein expression in breast cancer is limited. This review aims to provide a comprehensive understanding of the interaction between Bcl-2 proteins and caspases in the regulation of apoptosis, as well as the impact of dietary bioactive compounds on the modulation of anti-apoptotic Bcl-2 in breast cancer. It further explores how these interactions influence breast cancer progression and treatment outcomes.

Abstract
Recently, consumers have become increasingly interested in natural, health-promoting, and chronic disease-preventing medicine and food homology (MFH). There has been accumulating evidence that many herbal medicines, including MFH, are biologically active due to their biotransformation through the intestinal microbiota. The emphasis of scientific investigation has moved from the functionally active role of MFH to the more subtle role of biotransformation of the active ingredients in probiotic-fermented MFH and their health benefits. This review provides an overview of the current status of research on probiotic-fermented MFH. Probiotics degrade toxins and anti-nutritional factors in MFH, improve the flavor of MFH, and increase its bioactive components through their transformative effects. Moreover, MFH can provide a material base for the growth of probiotics and promote the production of their metabolites. In addition, the health benefits of probiotic-fermented MFH in recent years, including antimicrobial, antioxidant, anti-inflammatory, anti-neurodegenerative, skin-protective, and gut microbiome-modulating effects, are summarized, and the health risks associated with them are also described. Finally, the future development of probiotic-fermented MFH is prospected in combination with modern development technologies, such as high-throughput screening technology, synthetic biology technology, and database construction technology. Overall, probiotic-fermented MFH has the potential to be used in functional food for preventing and improving people's health. In the future, personalized functional foods can be expected based on synthetic biology technology and a database on the functional role of probiotic-fermented MFH.

Abstract
Polymethoxylated flavonoids (PMFs) are a subclass of flavonoids found in citrus fruits that have shown multifunctional biological activities and potential anticancer effects against breast cancer. We studied the absorption, metabolism, species source, toxicity, anti-cancer mechanisms, and molecular targets of PMFs to better utilize their anticancer activity against breast cancer. We discuss the absorption and metabolism of PMFs in the body, including the methylation, demethylation, and hydroxylation processes. The anticancer mechanisms of PMFs against breast cancer were also reviewed, including the estrogen activity, cytochrome P-450 enzyme system, and arylhydrocarbon receptor (AhR) inhibition, along with various molecular targets and potential anticancer effects. Although PMFs may be advantageous in the prevention and treatment for breast cancer, there is a lack of clinical evidence and data to support their efficacy. Despite their promise, there is still a long way to go before PMFs can be applied clinically.

Abstract
In the last years, the field of nanomedicine and drug delivery has grown exponentially, providing new platforms to carry therapeutic agents into the target sites. Extracellular vesicles (EVs) are ready-to-use, biocompatible, and non-toxic nanoparticles that are revolutionizing the field of drug delivery. EVs are involved in cell-cell communication and mediate many physiological and pathological processes by transferring their bioactive cargo to target cells. Recently, nanovesicles from plants (PDNVs) are raising the interest of the scientific community due to their high yield and biocompatibility. This study aims to evaluate whether PDNVs may be used as drug delivery systems. We isolated and characterized nanovesicles from tangerine juice (TNVs) that were comparable to mammalian EVs in size and morphology. TNVs carry the traditional EV marker HSP70 and, as demonstrated by metabolomic analysis, contain flavonoids, organic acids, and limonoids. TNVs were loaded with DDHD1-siRNA through electroporation, obtaining a loading efficiency of 13%. We found that the DDHD1-siRNA complex TNVs were able to deliver DDHD1-siRNA to human colorectal cancer cells, inhibiting the target expression by about 60%. This study represents a proof of concept for the use of PDNVs as vehicles of RNA interference (RNAi) toward mammalian cells.

Abstract
Although the Citrus tangerina cultivar “Dahongpao” (CTD) has been established as a rich source of polymethoxyflavones (PMFs) with anti-inflammatory and anti-cancer properties, their individual effects on cellular signaling remain to be elucidated. In this study, five major PMFs from the peel of CTD were isolated, including sinensetin, tetramethyl-O-scutellarin (5,6,7,4′-tetramethoxyflavone), nobiletin (5,6,7,8,3′, 4′-hexamethoxyflavone), tangeretin (5,6,7,8,4′-pentamethoxyflavone), and 5-demethylnobiletin (5-OH-6,7,8,3′,4′-pentamethoxyflavone). These PMFs were found to significantly (p < 0.05) inhibit the production of NO and biomarkers of chronic inflammation (TNF-α and IL-6). Additionally, they effectively suppressed mRNA biomarkers of acute inflammation (Cox-2 and iNOS), and to varying degrees promoted the activation of anti-inflammatory cytokines (IL-4, IL-13, TNF-β, and IL-10). Among the five PMFs, tangeretin was found to have a considerable anti-proliferative effect on tumor cell lines (PC-3 and DU145) and synergistically enhanced the cytotoxicity of mitoxantrone, partially via activation of the PTEN/AKT pathway. The findings of this study provide valuable insights into the activity of different PMF monomers and advance the understanding of the roles of PMFs in promoting apoptotic and anti-cancer effects.

Abstract
The contribution of autophagy to drug resistance has been studied in several cancers. However, there is no clear evidence about the role of autophagy in the resistance to chemotherapy in cancers, such as hepatocellular carcinoma (HCC). HCC is characterized by a poor prognosis and limited therapeutic options. Moreover, the emergence of multidrug-resistance (MDR) hinders successful treatment. Therefore, understanding how autophagy is regulated in resistant HCC is essential for sensitizing this malignancy to chemotherapy. This work demonstrated that basal and induced autophagy differ between parental and resistant Hep3B cells. In optimum growth conditions, the basal level of autophagy was low in resistant Hep3B (Hep3B-R) cells compared to the wild-type Hep3B (Hep3B-P) cells. However, in metabolic or therapeutic stress conditions, the rate of autophagy flux was much faster in the resistant cells. The work also confirmed the pro-survival function of autophagy in HCC. Besides, it demonstrated that the autophagy inhibitor, spautin, acted synergistically with fingolimod (FTY720) to promote cell death. The combination treatment resulted in superior reactive oxygen species (ROS) production and significant induction of apoptosis. In addition, spautin potentiated the effect of FTY720 against cell survival pathways like the Akt and ERK. Interestingly, the results indicated that Hep3B-R cells were more sensitive to autophagy inhibition than their parental counterparts. Collectively, this work revealed that combining spautin with chemotherapeutic agents that induce cytoprotective autophagy such as FTY720 is a promising approach to overcome MDR in HCC.

Abstract
Mitochondria are the cytoplasmic organelles mostly known as the "electric engine" of the cells; however, they also play pivotal roles in different biological processes, such as cell growth/apoptosis, Ca2+ and redox homeostasis, and cell stemness. In cancer cells, mitochondria undergo peculiar functional and structural dynamics involved in the survival/death fate of the cell. Cancer cells use glycolysis to support macromolecular biosynthesis and energy production ("Warburg effect"); however, mitochondrial OXPHOS has been shown to be still active during carcinogenesis and even exacerbated in drug-resistant and stem cancer cells. This metabolic rewiring is associated with mutations in genes encoding mitochondrial metabolic enzymes ("oncometabolites"), alterations of ROS production and redox biology, and a fine-tuned balance between anti-/proapoptotic proteins. In cancer cells, mitochondria also experience dynamic alterations from the structural point of view undergoing coordinated cycles of biogenesis, fusion/fission and mitophagy, and physically communicating with the endoplasmic reticulum (ER), through the Ca2+ flux, at the MAM (mitochondria-associated membranes) levels. This review addresses the peculiar mitochondrial metabolic and structural dynamics occurring in cancer cells and their role in coordinating the balance between cell survival and death. The role of mitochondrial dynamics as effective biomarkers of tumor progression and promising targets for anticancer strategies is also discussed.

Abstract
Drug resistance is responsible for the failure of many available anticancer drugs. Several studies have demonstrated the association between the alteration in sphingolipids (SPLs) and the development of drug resistance. To investigate the association between SPLs metabolism and doxorubicin (dox)-resistance in MCF-7 cells, a comparative sphingolipidomics analysis between dox-sensitive (parental) and -resistant MCF-7 cell lines along with validation by gene expression analysis were conducted. A total of 31 SPLs representing 5 subcategories were identified. The data obtained revealed that SPLs were clustered into two groups differentiating parental from dox-resistant cells. Eight SPLs were significantly altered in response to dox-resistance including SM (d18:1/16), SM (d18:1/24:2), SM (d18:1/24:0), SM (d18:1/20:0), SM (d18:1/23:1), HexCer (d18:1/24:0), SM (d18:1/15:0), DHSM (d18:0/20:0). The current study is the first to conclusively ascertain the potential involvement of dysregulated SPLs in dox-resistance in MCF-7 cells. SPLs metabolism in dox-resistant MCF-7 cells is oriented toward the downregulation of ceramides (Cer) and the concomitant increase in sphingomyelin (SM). Gene expression analysis has revealed that dox-resistant cells tend to escape from the Cer-related apoptosis by the activation of SM-Cer and GluCer-LacCer-ganglioside pathways. The enzymes that were correlated to the alteration in SPLs metabolism of dox-resistant MCF-7 cells and significantly altered in gene expression can represent potential targets that can represent a winning strategy for the future development of promising anticancer drugs.

Abstract
The emergence of multidrug resistance (MDR) is among the crucial obstacles to breast cancer therapy success. The transcription factor nuclear factor (NF)-κB is correlated to the pathogenesis of breast cancer and resistance to therapy. NF-κB augments the expression of MDR1 gene, which encodes for the membrane transporter P-glycoprotein (P-gp) in cancer cells. Since NF-κB activity is considered to be relatively high in particular when it comes to breast cancer, in the present work, we proposed that the inhibition of NF-κB activity can augment and enhance the sensitivity of breast cancer cells to chemotherapy such as doxorubicin (DOX) by virtue of MDR modulation. Our results demonstrated that the DOX-resistant MCF-7 and MDA-MB-231 clones exhibit higher NF-κB (p65) activity, which is linked to the upregulated expression of ABCB1 and ABCC1 transporter proteins. Combined treatment with NF-kB inhibitors (pentoxifylline and bortezomib) sensitized the resistant breast cancer cells to DOX. Such synergy was compromised by forced overexpression of p65. The DOX/NF-κB inhibitor combinations hampered NF-κB (p65) activation and downregulated MDR efflux transporters' level. Breast cancer cell migration was sharply suppressed in cells co-treated with DOX/NF-κB inhibitors. The same treatments successfully enhanced DOX-mediated induction of apoptosis, which is reflected by the elevated ratio of annexin-V/PI positively stained cells, along with the activation of other apoptotic markers. In conclusion, the data generated from this study provide insights for future translational investigations introducing the use of the clinically approved NF-κB inhibitors as an adjuvant in the treatment protocols of resistant breast cancer to overcome the multidrug resistance and enhance the therapeutic outcomes.
