Folate-conjugated nanoparticles as a potent therapeutic approach in targeted cancer therapy
The selective and efficient drug delivery to tumor cells can remarkably improve different cancer therapeutic approaches. There are several nanoparticles (NPs) which can act as a potent drug carrier for cancer therapy. However, the specific drug delivery to cancer cells is an important issue which should be considered before designing new NPs for in vivo application. It has been shown that cancer cells over-express folate receptor (FR) in order to improve their growth. As normal cells express a significantly lower levels of FR compared to tumor cells, it seems that folate molecules can be used as potent targeting moieties in different nanocarrier-based therapeutic approaches. Moreover, there is evidence which implies folate-conjugated NPs can selectively deliver anti-tumor drugs into cancer cells both in vitro and in vivo. In this review, we will discuss about the efficiency of different folate-conjugated NPs in cancer therapy. © 2015, International Society of Oncology and BioMarkers (ISOBM)

IL-21 and IL-21 receptor in the immunopathogenesis of multiple sclerosis
Cytokines are considered important factors in the modulation of various immune responses. Among them, interleukin (IL)-21 is one of the major immune modulators, adjusting various immune responses by affecting various immune cells. It has been suggested that IL-21 may enhance autoimmunity through different mechanisms, such as development and activation of helper T (T-H)-17 and follicular helper T (T-FH) cells, activation of natural killer (NK) cells, enhancing B-cell differentiation and antibody secretion and suppression of regulatory T (T-reg) cells. Moreover, IL-21 has also been suggested to be an inducer of autoimmunity when following treatment of MS patients with some therapeutics such as alemtuzumab. This review will seek to clarify the precise role of IL-21/IL-21R in the pathogenesis of MS and, in its animal model, experimental autoimmune encephalomyelitis (EAE)
Dimethyl fumarate: Regulatory effects on the immune system in the treatment of multiple sclerosis
Dimethyl fumarate (DMF) is an important oral treatment option for various autoimmune diseases, such as multiple sclerosis (MS) and psoriasis. DMF and its dynamic metabolite, monomethyl fumarate (MMF) are the major compounds that exert therapeutic effects on several pathologic conditions in part, through downregulation of immune responses. The exact mechanism of DMF is yet to be fully understood even though its beneficial effects on the immune system are extensively studied. It has been shown that DMF/MMF can affect various immune cells, which can get involved in both the naive and adaptive immune systems, such as T cells, B cells, dendritic cells, macrophages, neutrophils, and natural killer cells. It is suggested that DMF/MMF may exert their effect on immune cells through inhibition of nuclear factor-kappaB translocation, upregulation of nuclear factor erythroid-derived 2(E2)-related factor antioxidant pathway, and activation of hydroxyl carboxylic acid receptor 2. In this review, the mechanisms underlying the modulatory functions of DMF or MMF on the main immune cell populations involved in the immunopathogenesis of MS are discussed
Cancer associated fibroblasts as novel promising therapeutic targets in breast cancer
Breast cancer is one of the most important women-related malignancies, which is incurable (particularly in advanced stages) and tumor microenvironment is a number one accused part in the inefficiency of current anti-breast cancer therapeutic strategies. The tumor microenvironment is composed of various cellular and acellular components, which provide an optimum condition for freely expanding cancer cells in various cancer types, particularly breast cancer. Cancer-associated fibroblasts (CAFs) are one of the main cell types in the breast tumor region, which can promote various tumor-promoting processes such as expansion, angiogenesis, metastasis and drug resistance. CAFs directly (by cell-to-cell communication) and indirectly (through secreting soluble factors) can exert their tumorigenic functions. We try to elucidate the immunobiology of CAFs, their origin, function, and heterogeneity in association with their role in various cancer-promoting processes in breast cancer. Based on current knowledge, we believe that the origin of CAFs, their subsets, and their specific expressed biomarkers determine their pro- or anti-tumor functions. Therefore, targeting CAF without considering their specific functions may lead to a deleterious outcome. We propose to find and characterize each subtype of CAFs in association with its specific function in different stages of breast cancer to develop novel promising therapeutic approaches against the right CAF subtype
Tumor associated macrophages in the molecular pathogenesis of ovarian cancer
The tumor microenvironment is a critical factor that enhances cancer progression, drug resistance, and failure of therapeutic approaches. Several cellular and non-cellular factors are involved in cancer promotion. Among the several cell populations in the tumor microenvironment, macrophages, as one of the most abundant innate immune cells within the tumor milieu, have attracted extensive attention among several researchers because of their critical role in innate pathophysiology of multiple disorders, as well as ovarian cancer. High plasticity and consequent high ability to adapt to environmental alternations by adjusting their cellular metabolism and immunological phenotype is the notable characteristic of macrophages. Therefore, the critical function of tumor-associated macrophages in ovarian cancer is highlighted in the growing body of recent studies. In this article, we will comprehensively focus on significant impacts of the macrophages on ovarian cancer progression, by discussing the role of macrophages as one of the fundamental immune cells present in tumor milieu, in metabolic reprogramming of transformed cells, and involvement of these cells in the ovarian cancer initiation, progression, invasion, and angiogenesis. Moreover, we will summarise recent studies evaluating the effects of targeting macrophages in ovarian cancer
Anti-angiogenic effects of CD73-specific siRNA-loaded nanoparticles in breast cancer-bearing mice
CD73 facilitates tumor growth by upregulation of the adenosine (immunosuppressive factor) in the tumor microenvironment, however, its precise molecular mechanisms is not precisely understood. Regarding the importance of angiogenesis in tumor development and spreading, we decided to assign the anti-angiogenic effects of CD73 suppression. We used chitosan lactate (ChLa) nanoparticles (NPs) to deliver CD73-specific small interfering RNA (siRNA) into cancer cells. Our results showed that treatment of the 4T1 cells with CD73-specific siRNA-loaded NPs led to potent inhibition of cancer cell proliferation and cell cycle arrest, in vitro. This growth arrest was correlated with downregulation of angiogenesis-related molecules including vascular endothelial growth factor (VEGF)-A, VEGF-R2, interleukin (IL)-6, and transforming growth factor (TGF)-beta. Moreover, administration of NPs loaded with CD73-siRNA into 4T1 breast cancer-bearing mice led to tumor regression and increased mice survival time accompanied with downregulation of angiogenesis (VEGF-A, VEGF-R2, VE-Cadherin, and CD31) and lymphangiogenesis (VEGF-C and LYVE-1)-related genes in the tumor site. Furthermore, the expression of angiogenesis promoting factors including IL-6, TGF-beta, signal transducer, and activator of transcription (STAT)3, hypoxia inducible factor (HIF)-1alpha, and cyclooxygenase (COX)2 was decreased after the CD73 suppression in mice. Moreover, analysis of leukocytes derived from the tumor samples, spleen, and regional lymph nodes showed that they had lower capability for secretion of angiogenesis promoting factors after CD73-silencing. These results indicate that suppression of tumor development by downregulation of CD73 is in part related to angiogenesis arrest. These findings imply a promising strategy for inhibiting tumor growth accompanied with suppressing the angiogenesis proces
S1PR1 as a Novel Promising Therapeutic Target in Cancer Therapy
Sphingosine-1-phosphate (S1P) can regulate several physiological and pathological processes. S1P signaling via its cell surface receptor S1PR1 has been shown to enhance tumorigenesis and stimulate growth, expansion, angiogenesis, metastasis, and survival of cancer cells. S1PR1-mediated tumorigenesis is supported and amplified by activation of downstream effectors including STAT3, interleukin-6, and NF-κB networks. S1PR1 signaling can also trigger various other signaling pathways involved in carcinogenesis including activation of PI3K/AKT, MAPK/ERK1/2, Rac, and PKC/Ca, as well as suppression of cyclic adenosine monophosphate (cAMP). It also induces immunological tolerance in the tumor microenvironment, while the immunosuppressive function of S1PR1 can also lead to the generation of pre-metastatic niches. Some tumor cells upregulate S1PR1 signaling pathways, which leads to drug resistant cancer cells, mainly through activation of STAT3. This signaling pathway is also implicated in some inflammatory conditions leading to the instigation of inflammation-driven cancers. Furthermore, it can also increase survival via induction of anti-apoptotic pathways, for instance, in breast cancer cells. Therefore, S1PR1 and its signaling pathways can be considered as potential anti-tumor therapeutic targets, alone or in combination therapies. Given the oncogenic nature of S1PR1 and its distribution in a variety of cancer cell types along with its targeting advantages over other molecules of this family, S1PR1 should be considered a favorable target in therapeutic approaches to cancer. This review describes the role of S1PR1 in cancer development and progression, specifically addressing breast cancer, glioma, and hematopoietic malignancies. We also discuss the potential use of S1P signaling modulators as therapeutic targets in cancer therapy
