The effect of micronutrients, including Vitamin K, on various cancer cell lines has been widely studied, but the potential anticancer effect of VK3-OCH3, an analog of vitamin K3 (Menadione), on African American prostate cancer has not been evaluated. In this study, we compared the anticancer effect of VK3-OCH3 on targeting African American derived PCa cell lines namely RC77-T and MDA-PCa-2b. Our results show that VK3-OCH3 significantly inhibits the proliferation of both RC77-T and MDA-PCa-2b African American PCa cells and promotes apoptosis, and the underlying mechanism of cell death appears to be similar in both the cell lines. Notably, VK3-OCH3 inhibits colony-forming ability and induces apoptosis by blocking the cell cycle at G0 in African American PCa cells. VK3-OCH3 also acts as an anti-metastatic agent by inhibiting the migration ability of the metastatic properties of African American PCa cells. The cell death of African American PCa cells mediated by VK3-OCH3 is associated with the production of free radicals, such as intracellular and mitochondrial reactive oxygen species (ROS). Interestingly, antioxidants such as N-Acetylcysteine (NAC) and Glutathione (GSH) effectively negated the oxidative stress induced by VK3-OCH3 on PCa cell lines derived from African American patients. Of note, VK3-OCH3 reduces androgen receptor and prostate-specific antigen expression in these PCa cells. Furthermore, molecular dynamic studies reiterated that VK3-OCH3 strongly binds to the androgen receptor, suggesting that the androgen receptor is the potential molecular target of VK3-OCH3. In addition, Western blot analysis showed that VK3-OCH3 reduces the expression of androgen receptor, TRX2, and anti-apoptotic signaling molecules such as Bcl-2 and TCTP in the MDA-PCa-2b metastatic PCa cellular model. In conclusion, our results suggested that VK3-OCH3 is a promising anticancer agent that could potentially reduce the mortality rates of African American PCa patients, warranting further preclinical and translational studies.</p>","PeriodicalId":8923,"journal":{"name":"BioFactors","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142118915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lotus seedpod extract (LSE) has demonstrated anticancer effects in various cancer cells. However, its potential against radioresistant tumors remains unclear. In this study, we aimed to investigate the effect of LSE on radioresistant breast cancer cells, explore the underlying mechanism, and identify the major constituents responsible for its cytotoxic effect. LSE, extracted using 70% ethanol, exhibited selective cytotoxic effects against radioresistant breast cancer cells compared with their parental cells. Chemical analysis identified quercetin and its derivatives, hyperoside and miquelianin, as the major constituents responsible for these selective effects. Notably, quercetin displayed the most potent cytotoxicity against radioresistant breast cancer cells compared with hyperoside and miquelianin. Further investigation revealed that these compounds inhibited the activation of DNA repair systems, leading to the accumulation of DNA damage and the induction of apoptosis. Importantly, they efficiently suppressed the expression of ACSL4, a factor previously associated with radioresistance. In an in vivo study, quercetin exhibited a significant suppression of tumor growth in radioresistant tumor-bearing mice. Taken together, our findings highlight the potential of LSE and its major constituents, quercetin and its derivatives, in overcoming radioresistance in breast cancer. This study provides compelling evidence to support the use of LSE as a medicinal source for the future adjunctive therapy to combat radioresistance in breast cancers.</p>","PeriodicalId":8923,"journal":{"name":"BioFactors","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142016254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Propolis has been widely recognized as a functional food due to its diverse range of beneficial bioactivities. However, the therapeutic effects of consuming propolis against atopic dermatitis (AD) remain largely unknown. The current study aimed to investigate the potential efficacy of propolis against AD and explore the active compound as well as the direct molecular target. In HaCaT keratinocytes, propolis inhibited TNF-α-induced interleukin (IL)-6 and IL-8 secretion. It also led to a reduction in chemokines such as monocyte chemoattractant protein-1 (MCP-1) and macrophage-derived chemokine (MDC), while restoring the levels of barrier proteins, filaggrin and involucrin. Propolis exhibited similar effects in AD-like human skin, leading to the suppression of AD markers and the restoration of barrier proteins. In DNCB-induced mice, oral administration of propolis attenuated AD symptoms, improved barrier function, and reduced scratching frequency and transepidermal water loss (TEWL). In addition, propolis reversed the mRNA levels of AD-related markers in mouse dorsal skin. These effects were attributed to caffeic acid phenethyl ester (CAPE), the active compound identified by comparing major components of propolis. Mechanistic studies revealed that CAPE as well as propolis could directly and selectively target MKK4.

This study aimed to assess the effects of limonene on intestinal epithelial barrier function and investigate the involvement of cannabinoid receptor type-1 (CB1R) in vitro. Additionally, the study focused on examining the metabolomic changes induced by limonene in the intestinal epithelial cells (Caco-2). Initial analysis of transepithelial electrical resistance (TEER) revealed that both l-limonene and d-limonene, isomers of limonene, led to a dose- and time-dependent increase in TEER in normal cells and those inflamed by pro-inflammatory cytokines mixture (CytoMix). Furthermore, both types of limonene reduced CytoMix-induced paracellular permeability, as demonstrated by a decrease in Lucifer yellow flux. Moreover, d-limonene and l-limonene treatment increased the expression of tight junction molecules (TJs) such as occludin, claudin-1, and ZO-1, at both the transcriptional and translational levels. d-Limonene upregulates E-cadherin, a molecule involved in adherens junctions (AJs). Mechanistic investigations demonstrated that d-limonene and l-limonene treatment significantly inhibited CB1R at the protein, while the mRNA level remained unchanged. Notably, the inhibitory effect of d-limonene on CB1R was remarkably similar to that of pharmacological CB1R antagonists, such as rimonabant and ORG27569. d-limonene also alters Caco-2 cell metabolites. A substantial reduction in β-glucose and 2-succinamate was detected, suggesting limonene may impact intestinal epithelial cells' glucose uptake and glutamate metabolism. These findings suggest that d-limonene's CB1R antagonistic property could effectively aid in the recovery of intestinal barrier damage, marking it a promising gastrointestinal protectant.</p>","PeriodicalId":8923,"journal":{"name":"BioFactors","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141981585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research is to compare the potential effects of a viable probiotic (Lactobacillus rhamnosus GG) with those exerted by its heat-inactivated paraprobiotic counterpart in a dietary rodent model of NAFLD. The probiotic administration effectively prevented the hepatic lipid accumulation induced by a high-fat high-fructose diet feeding, as demonstrated by chemical (lower TG content) and histological (lower steatosis grade and lobular inflammation) analyses. This effect was mainly mediated by the downregulation of lipid uptake (FATP2 protein expression) and upregulating liver TG release to bloodstream (MTTP activity) in rats receiving the probiotic. By contrast, the effect of the paraprobiotic preventing diet-induced liver lipid accumulation was milder, and mainly derived from the downregulation of hepatic de novo lipogenesis (SREBP-1c protein expression and FAS activity) and TG assembly (DGAT2 and AQP9 protein expression).

Ionizing radiation (IR) can harm healthy cells, but as radiotherapy remains crucial in cancer treatment. Owing to the remarkable application of radiotherapy in the treatment of cancers, it is vital to protect healthy cells from radiation hazards while increasing the sensitivity of cancer cells to radiation. This article reviews the current understanding of apigenin's radioprotective and radiosensitive properties with a focuses on the involved signaling pathways and key molecular targets. When exposed to irradiation, apigenin reduces inflammation via cyclooxygenase-2 inhibition and modulates proapoptotic and antiapoptotic biomarkers. Apigenin's radical scavenging abilities and antioxidant enhancement mitigate oxidative DNA damage. It inhibits radiation-induced mammalian target of rapamycin activation, vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP), and STAT3 expression, while promoting AMPK, autophagy, and apoptosis, suggesting potential in cancer prevention. As a radiosensitizer, apigenin inhibits tumor growth by inducing apoptosis, suppressing VEGF-C, tumor necrosis factor alpha, and STAT3, reducing MMP-2/9 activity, and inhibiting cancer cell glucose uptake. Cellular and animal studies support apigenin's radioprotective and anticancer potential, making it a potential candidate for further research.
