Abstract
Colorectal cancer (CRC) is a common malignant tumor worldwide. Capsaicin and cold exposure were positively correlated with CRC metastasis. However, the mechanisms of action underlying capsaicin and cold exposure in 1,2-dimethylhyrazine (DMH)-induced CRC remain unknown. Multiple assays were utilized in the present study, including methylene blue, hematoxylin eosin (H&E) and immunohistochemistry (IHC) staining, western blotting and Duolink proximity ligation assay (PLA), in order to assess the influence of capsaicin and cold exposure on CRC rat models induced by DMH. The present study reported that capsaicin and cold exposure treatment significantly increased the size and number of colonic tumors, and the CRC metastasis rate in the capsaicin and cold exposure groups was higher than that in DMH model group.Moreover, it was observed that capsaicin and cold exposure increased mRNA and protein expression levels of LAMC2 and integrin-β1 induced by DMH. Duolink PLA results indicated that cold exposure and capsaicin significantly promoted interaction formation between LAMC2 and ITGB1 in CRC rats induced by DMH. Furthermore, western blot and IHC analysis confirmed that cold exposure and capsaicin inhibited DMH-induced decreases in the expression levels of E-cadherin, and increases in the expression levels of p-FAK, Snails, Fibronectin and N-cadherin. In addition, the serum levels of IL-1β and IL-6 in capsaicin and cold exposure group were higher than those of model group. In conclusion, our study suggests that both capsaicin and cold exposure may contribute to EMT-mediated the formation of premetastatic niche, which may lead to CRC metastasis by activating the early interaction between LAMC2 and integrin-β1.

Basic concepts, introduction, and future resource for vaccine adjuvant discovery. Front Oncol 2023; 13:1180084. [PMID: 37588095 PMCID: PMC10426289 DOI: 10.3389/fonc.2023.1180084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 05/30/2023] [Indexed: 08/18/2023] Open
Abstract
The presence of microorganism communities (MOCs) comprised of bacteria, fungi, archaea, algae, protozoa, viruses, and the like, are ubiquitous in all living tissue, including plant and animal. MOCs play a significant role in establishing innate and acquired immunity, thereby influencing susceptibility and resistance to disease. This understanding has fostered substantial advancements in several fields such as agriculture, food science/safety, and the development of vaccines/adjuvants, which rely on administering inactivated-attenuated MOC pathogens. Historical evidence dating back to the 1800s, including reports by Drs Busch, Coley, and Fehleisen, suggested that acute febrile infection in response to "specific microbes" could trigger spontaneous tumor remission in humans. This discovery led to the purposeful administration of the same attenuated strains, known as "Coley's toxin," marking the onset of the first microbial (pathogen) associated molecular pattern (MAMPs or PAMPs)-based tumor immunotherapy, used clinically for over four decades. Today, these same MAMPS are consumed orally by billions of consumers around the globe, through "specific" mediums (immune boosting "herbal supplements") as carriers of highly concentrated MOCs accrued in roots, barks, hulls, sea algae, and seeds. The American Herbal Products Association (AHPA) mandates microbial reduction in botanical product processing but does not necessitate the removal of dead MAMP laden microbial debris, which we ingest. Moreover, while existing research has focused on the immune-modulating role of plant phytochemicals, the actual immune-boosting properties might instead reside solely in the plant's MOC MAMP laden biomass. This assertion is logical, considering that antigenic immune-provoking epitopes, not phytochemicals, are known to stimulate immune response. This review explores a neglected area of research regarding the immune-boosting effects of the herbal microbiome - a presence which is indirectly corroborated by various peripheral fields of study and poses a fundamental question: Given that food safety focuses on the elimination of harmful pathogens and crop science acknowledges the existence of plant microbiomes, what precisely are the immune effects of ingesting MAMPs of diverse structural composition and concentration, and where are these distributed in our botanicals? We will discuss the topic of concentrated edible MAMPs as acid and thermally stable motifs found in specific herbs and how these would activate cognate pattern recognition receptors (PPRs) in the upper gut-associated lymphoid tissue (GALT), including Peyer's patches and the lamina propria, to boost antibody titers, CD8+ and CD4+ T cells, NK activity, hematopoiesis, and facilitating M2 to M1 macrophage phenotype transition in a similar manner as vaccines. This new knowledge could pave the way for developing bioreactor-grown/heat-inactivated MOC therapies to boost human immunity against infections and improve tumor surveillance.

He P, Dai Q, Wu X. New insight in urological cancer therapy: From epithelial-mesenchymal transition (EMT) to application of nano-biomaterials. ENVIRONMENTAL RESEARCH 2023; 229:115672. [PMID: 36906272 DOI: 10.1016/j.envres.2023.115672] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 03/07/2023] [Accepted: 03/09/2023] [Indexed: 05/21/2023]
Abstract
A high number of cancer-related deaths (up to 90) are due to metastasis and simple definition of metastasis is new colony formation of tumor cells in a secondary site. In tumor cells, epithelial-mesenchymal transition (EMT) stimulates metastasis and invasion, and it is a common characteristic of malignant tumors. Prostate cancer, bladder cancer and renal cancer are three main types of urological tumors that their malignant and aggressive behaviors are due to abnormal proliferation and metastasis. EMT has been well-documented as a mechanism for promoting invasion of tumor cells and in the current review, a special attention is directed towards understanding role of EMT in malignancy, metastasis and therapy response of urological cancers. The invasion and metastatic characteristics of urological tumors enhance due to EMT induction and this is essential for ensuring survival and ability in developing new colonies in neighboring and distant tissues and organs. When EMT induction occurs, malignant behavior of tumor cells enhances and their tend in developing therapy resistance especially chemoresistance promotes that is one of the underlying reasons for therapy failure and patient death. The lncRNAs, microRNAs, eIF5A2, Notch-4 and hypoxia are among common modulators of EMT mechanism in urological tumors. Moreover, anti-tumor compounds such as metformin can be utilized in suppressing malignancy of urological tumors. Besides, genes and epigenetic factors modulating EMT mechanism can be therapeutically targeted for interfering malignancy of urological tumors. Nanomaterials are new emerging agents in urological cancer therapy that they can improve potential of current therapeutics by their targeted delivery to tumor site. The important hallmarks of urological cancers including growth, invasion and angiogenesis can be suppressed by cargo-loaded nanomaterials. Moreover, nanomaterials can improve chemotherapy potential in urological cancer elimination and by providing phototherapy, they mediate synergistic tumor suppression. The clinical application depends on development of biocompatible nanomaterials.

Abstract
Transcription factors involve many proteins in the process of transactivating or transcribing (none-) encoded DNA to initiate and regulate downstream signals, such as RNA polymerase. Their unique characteristic is that they possess specific domains that bind to specific DNA element sequences called enhancer or promoter sequences. Epithelial-mesenchymal transition (EMT) is involved in cancer progression. Many dysregulated transcription factors-such as Myc, SNAIs, Twists, and ZEBs-are key drivers of tumor metastasis through EMT regulation. This review summarizes currently available evidence related to the oncogenic role of classified transcription factors in EMT editing and epigenetic regulation, clarifying the roles of the classified conserved transcription factor family involved in the EMT and how these factors could be used as therapeutic targets in future investigations.

Hesperidin ameliorates benign prostatic hyperplasia by attenuating cell proliferation, inflammatory response, and epithelial-mesenchymal transition via the TGF-β1/Smad signaling pathway. Biomed Pharmacother 2023; 160:114389. [PMID: 36791565 DOI: 10.1016/j.biopha.2023.114389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 01/30/2023] [Accepted: 02/07/2023] [Indexed: 02/15/2023] Open
Abstract
Excessively activated transforming growth factor-beta 1 (TGF-β1) exacerbates benign prostatic hyperplasia (BPH) by triggering epithelial-mesenchymal transition (EMT) as well as epithelial and stromal cell differentiation. Hesperidin (HSP), a flavanone rich in citrus peels, exhibits a safe anti-cancer activity with few side effects. Although HSP reportedly inhibits cell growth in prostate cancer, studies on BPH have not yet been reported. Thus, this study aimed to figure out the therapeutic effect of HSP and its underlying mechanisms in BPH models in vivo and in vitro. To evaluate the anti-BPH effect of HSP in vivo, rats were injected with testosterone propionate (TP; 10 mg/kg, s.c.), finasteride (5 mg/kg, p.o.), and HSP (50 and 100 mg/kg, i.p.) for four weeks. The in vitro efficacy of HSP was evaluated using two prostate cell models, BPH-1 and dihydrotestosterone-stimulated WPMY-1 cells, for studying the interaction between epithelial and stromal cells. Both in vivo and in vitro, HSP inhibited prostate cell proliferation by suppressing the expression of androgen receptor-related markers. In addition, HSP reduced the expression levels of inflammatory and mesenchymal markers by blocking TGF-β1 activation. Collectively, HSP alleviated BPH by attenuating prostate cell proliferation, the inflammatory response, and EMT by regulating the TGF-β1/Smad signaling pathway. Thus, these results provide evidence for a new therapeutic approach against BPH.

Abstract
Currently, medication for benign prostate hyperplasia (BPH) and prostate cancer (PCa) are mainly based on modulating the hormone and nervous systems. However, side effects often affect patients, and might decrease their commitment to continuing the medication and lower their quality of life. Some studies have indicated that chronic inflammation might be the cause of BPH and PCa. Based on this hypothesis, the effect of phloretin, a potent anti-inflammatory and anti-oxidative flavonoid, has been researched since 2010. Results from animal and in-vitro studies, obtained from databases, also indicate that the use of phloretin in treating BPH and PCa is promising. Due to its effect on inflammatory cytokines, apoptosis or anti-apoptosis, reactive oxygen species, anti-oxidant enzymes and oxidative stress, phloretin is worthy of further study in human clinical trials regarding safety and effective dosages.
