The designing of controlled drug delivery at a nanoscale level to target tumor cells is known as the nano-drug delivery system (NDDS). Nanoparticles (NPs) - based NDDS has distinct advantages over traditional pharmaceuticals, including greater stability and biocompatibility, enhanced permeability and retention effect (EPR), and precisely targeted tumor tissue. Near-infrared (NIR) light-responsive NPs utilized for photothermal effects are called photothermal therapy (PTT). PTT is the most significant aspect of nanotechnology to cure tumors because, thermal heat energy directly induces tumor ablation, without any normal cell damage and side effects. Chemotherapy is one of the most efficient strategies for cancer therapy but it has side effects. Cancer immunotherapy aims to reactivate autoimmune responses for fighting cancer cells. Hence, the combination of chemotherapy, PTT, and Immunotherapy can be efficiently achieved to enhance antitumor efficacy. This comprehensive review is mainly focused on the combined therapeutic effects of chemo-PTT (CPTT) and photothermal immunotherapy (PIT) on cancer treatment and metastatic inhibition. Nowadays, a specific combination of CPTT and PIT is one of the most effective methods to treat cancers. Therefore, the combined therapeutic approach has a great potential effect to fight against cancer for tumor regression and metastatic inhibition.</p></div>","PeriodicalId":72083,"journal":{"name":"Advances in cancer biology - metastasis","volume":"4 ","pages":"Article 100044"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667394022000181/pdfft?md5=48a69450fc017d0e8a7e2cb7f02f095a&pid=1-s2.0-S2667394022000181-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48383266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tumor heterogeneity involves interactions among cancer cells and stromal cells, such as mesenchymal stem cells (MSCs), that are recruited into the tumor microenvironment and migrate to the tumor site. Here, we characterized the impact of kinin receptors on the interaction of MSCs with GB cells which is further enhanced by kinin receptor agonists. Interactions between GB cells and MSCs were studied in two- and three-dimensional co-cultures. Kinin receptor activity was modulated by selective agonists and antagonists to evaluate their influence on cell viability, cell-cell interactions, GB U87 cell invasiveness, and phenotype alterations. Tumor cell invasion was enhanced by the kinin-B2 receptor agonist bradykinin, while it was blocked by B2 receptor antagonists applied in U87 cells monoculture and in co-culture with MSCs. Kinin receptor inhibition correlated with enhanced direct U87/MSC interactions, such as heterotypic fusion, vesicle transfer and entosis. Furthermore, kinin receptor modulation influenced expression of F-actin expression and genes associated with epithelial-to-mesenchymal transition in U87 cells upon U87/MSCs co-cultures.

It is typically diagnosed after it has spread from the primary site to the secondary site. Exosomes are membrane-bound nanovesicles that play a critical role in tumor biology and metastasis by promoting intercellular communication. Tumor-associated exosome populations are widely acknowledged to be heterogenous, as various cell types and hallmark tumor microenvironment stressors impact exosome synthesis. Ovarian cancer cells metastasize using intraperitoneal fluids that are rich in exosomes, suggesting that these circulating exosomes assist detached cancer cells to maintain invasive phenotypes prior to secondary site invasion. Studies show that tumor-secreted exosomes direct organ-specific colonization by fusing exosome integrins with target cells in a tissue-specific fashion. Exosome signaling molecules (mRNA, miRNA, proteins) are encapsulated by cholesterol-rich membranes, and thus protects biomaterials from enzymatic degradation. Therefore, they represent an ideal system for studying the expression of sensitive proteins and RNA and for future drug delivery vehicles. Proteins and RNA exchanged through exosomes also influence the molecular and mechanical properties of ovarian cancer cells promoting adaptations that contribute to invasive and metastatic cell behavior. Tumor-derived exosomes also interact with stromal cells to alter their molecular profiles, thus promoting the development of a more malignant tumor microenvironment (TME), invasive cell behavior, and cancer progression. This review provides an overview on exosome structure and biogenesis and summarizes recent studies on ovarian cancer exosomes, exosome mediated interactions in the tumor microenvironment, and exosome heterogeneity.</p></div>","PeriodicalId":72083,"journal":{"name":"Advances in cancer biology - metastasis","volume":"4 ","pages":"Article 100040"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667394022000144/pdfft?md5=fdeea657ba9b65c941372859563f41ae&pid=1-s2.0-S2667394022000144-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47418216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, elevated expression of Gankyrin modulates the key signaling pathways such as JNK, PI3K/AKT, and mTOR, avidly involved in the regulation of cell cycle, apoptosis, and cell fate decisions, thus resulting in the process of tumorigenesis and metastasis. Contrastingly, downregulated expression of Gankyrin exerts anticancer effects. Evidently, a number of emerging reports revealed Gankyrin as a potential marker for the early detection of various cancers. Therefore, it is consistent with the notion that Gankyrin is a driver gene that serves not only to initiate the process of carcinogenesis, but also to progress into metastatic phenotype.

Sixty-five percent of breast cancers are estrogen and/or progesterone receptor positive. Estrogen receptor expression is a prognostic and predictive biomarker of response to endocrine therapy, which consists of the selective estrogen receptor modulator tamoxifen, aromatase inhibitors, and the selective estrogen receptor degrader fulvestrant. Cannabidiol is a phytocannabinoid that is emerging as a potential therapeutic agent. The aim of this study was to investigate the effect of cannabidiol on estrogen receptor-positive and estrogen receptor-negative representative breast cancer cell lines in combination with standard therapeutic agents used in clinical practice. To compare the effects of cannabidiol on breast cancer cell viability, cancer cell lines were exposed to increasing concentrations of cannabidiol. The effects of cannabidiol in combination with the endocrine therapeutics tamoxifen, fulvestrant, and the cyclin-dependent kinase inhibitor palbociclib on breast cancer cell viability were examined. We demonstrated that cannabidiol dose-dependently decreased the viability of all breast cancer cell lines independent of estrogen receptor expression. The addition of cannabidiol to tamoxifen had an additive negative effect on cell viability in ER+ ​in estrogen receptor positive T-47D line. Cannabidiol did not attenuate the effect of standard treatment of hormone receptor-positive breast cancer with fulvestrant and palbociclib.
