    Abstract The occurrence of viral infections and approaches to handling them are very challenging and require prompt diagnosis and timely treatment. Recently, genomic medicine approaches have come up with the discovery of the competing endogenous RNA (ceRNA) network, including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) on the basis of gene silencing. CircRNAs, as a group of non-encoded RNAs, make a loop-like structure by back-splicing through 3' and 5' ends. They are stable, abundant, specific, and highly conserved and can be quickly generated at large scales

    Abstract Hyperglycemia is known as one of the main causes of infertility in human societies. Indole propionic acid (IPA) is produced by intestinal microbiota and has antioxidant and anti-inflammatory properties. This study aims to investigate the effects of IPA on molecular indices of steroidogenesis, ER stress, and apoptosis induced by high glucose (HG) in granulosa cells. Primary GCs, isolated from ovarian follicles of Rats were cultured in 5 mM (control) and 30 mM (HG) of glucose and in the presence of 10 and 20 µM of IPA for 24 h. The cell viability was assessed by MTT. The gene expression of P450SCC, 3βHSD, CYP19A, BAX, BCL2, and STAR was evaluated by Real-Time PCR. Protein expression of ATF6, PERK, GRP78, and CHOP determined by western blot. Progesterone, estradiol, IL-1β, and TNF-α were measured by ELISA. HG decreased the viability, and expression of P450SCC, 3βHSD, CYP19A, BCL2, STAR, and increased BAX. 10 and 20 µM of IPA increased cell viability, expression of P450SCC, 3βHSD, CYP19A, BCL2 and STAR and decreased BAX compared to the HG group. The expression of ATF6, PERK, GRP78, and CHOP proteins increased by HG and IPA decreased the expression of these proteins compared to the HG group. Also, HG decreased progesterone and estradiol levels and increased IL-1β and TNF-α. IPA significantly increased progesterone and estradiol and decreased IL-1β and TNF-α compared to the HG group. IPA can improve the side effects of HG in GCs of rats, as responsible cells for fertility, by improving steroidogenesis, regulation of ER-stress pathway, suppression of inflammation, and apoptosis.

    Abstract Aflatoxins B1 (AFB1) a dangerous type of aflatoxin, poses a serious threat to human health. Meanwhile, Taraxasterol, a bioactive compound in dandelion, exhibits strong anti-inflammatory and antioxidant activity. Therefore, the aim of this study was to investigate the impact of AFB1 on the intrinsic and extrinsic pathways of apoptosis, as well as evaluate the protective role of taraxasterol in the TM3 Leydig cell line. Cell viability was evaluated using an MTT assay, measuring the effects of 3.6 µM AFB1 and varying concentrations of taraxasterol. Expression levels of Caspase 3,8, and 9 were analyzed with RT-qPCR, and flow cytometry was used to assess cell cycle progression and apoptotic alterations. The findings of this study demonstrated that exposure to 3.6 µM of AFB1 resulted in an upregulation of Caspase 3 and Caspase 9 expression, indicating an activation of apoptotic pathways in TM3 cells. Additionally, the analysis of apoptosis revealed a significant increase in cellular apoptosis at this AFB1 concentration. However, when TM3 cells were exposed to 5 µM of taraxasterol, a downregulation of Caspase 3 and Caspase 9 expression was observed, suggesting a protective effect against apoptosis. Moreover, the apoptotic rate in TM3 cells was reduced in the presence of 5 µM of taraxasterol. Consequently, this study highlights the potential of taraxasterol as a protective agent against AFB1-induced apoptosis and suggest its potential application in regulating cell survival and apoptosis-related processes. Further investigations are necessary to elucidate the underlying mechanisms and evaluate the clinical implications of taraxasterol in the context of fertility disorders and other conditions associated with AFB1 exposure.

    Abstract Colorectal cancer is the third most common cancer in the world. Due to the side effects of common treatments such as chemotherapy and radiotherapy, the use of herbal medicines has received much attention. Artemether (ARM) is an herbal medicine derived from artemisinin, which has many anti-tumor properties. However, factors such as low solubility and short half-life have limited the use of artemether in clinical practice. In this study, we aimed to reduce these limitations by encapsulating artemether in human serum albumin (HSA). The hydrodynamic diameter and the zeta potential value of ARM-ALB nanoparticles (NPs) were 171.3 ± 5.88 nm and -19.1 ± 0.82 mV, respectively. Comparison of the effect of free and encapsulated artemether on CT 26 cell line showed that the use of artemether in capsulated form can reduce the effective concentration of the drug. Additionally, in vivo studies have also shown that albumin-artemether nanoparticles can control tumor growth by increasing the production of cytokine IFN-γ and decreasing the production of IL4. Therefore, ARM-ALB nanoparticles have greater anti-tumor effects than free artemether.

    Abstract It is believed that preformed antibodies are responsible for blood transfusion reactions and transplant rejections. In order to remove a tumor, the tissue must be rejected. On the basis of transfusion reaction and transplantation immunology, we hypothesized that allogeneic serum can inhibit tumor growth when injected intra-tumor. Initially, an in vitro cytotoxicity test was conducted using the C57BL/6 serum (intact or decomplemented) in combination with the BALB/c-originating CT26 cell line.  The CT26 cell line was used to establish a mouse model of colon cancer. When the tumor was palpable, C57BL/6 serum was injected intra-tumor. In addition to tumor size, hypoxia, metastatic capacity, angiogenesis, and metabolic and inflammatory status, we evaluated matrix metalloproteinase-2 (MMP)-2 and 9, vascular endothelial growth factor (VEGF)-A, Cluster of Designation (CD) 31, CD38 and interleukine (IL)-10. An in vitro experiment showed that heat-inactivated C57BL/6 serum had significantly lower cytotoxic effects on BALB/c-derived CT26 cells than intact C57BL/6 serum or BALB/c serum. In vivo experiments revealed that tumor size, HIF-1α, MMP-2, and MMP-9 levels were significantly lower in the experimental group than in the control group. In contrast to control animals, allogeneic serum treatment led to marked reductions in CD31, VEGF-1, CD38, and IL-10 levels. A new approach to serum or plasma therapy and allogeneic vaccines for cancer is intra-tumor injection of allogeneic serum. In light of the ease and availability of allogeneic immunotherapies, allogeneic serum and plasma therapy could potentially be used as an alternative monotherapy or in combination with other therapies.

    Abstract Background and objectives: Despite promising successes in developing new drugs and pharmaceutical biotechnology, infectious diseases and cancer are still the principal causes of mortality and morbidity globally. Therefore, finding effective ways to deal with these pathogens and cancers is critical. Metal nanoparticles are one of the new strategies to combat bacteria and cancers.
    Methods: We examined the antimicrobial activity of 30 and 60 nm copper oxide nanoparticles (CuO-NPs) against Acinetobacter baumannii and Staphylococcus epidermidis bacteria responsible for nosocomial infections in standard and clinical strains and anti-cancer activity against 4T1 cell line as malignancy breast cancer cells. Synthesis of CuO-NPs was performed by a one-step reduction method and confirmed by DLS and TEM microscopy at 30 and 60 nm sizes. The antibacterial and anti-cancer activities of the nanoparticles were then investigated against the aforementioned bacteria and breast cancer.
    Results: Using disk, well, MIC, MBC methods, and viability/bacterial growth assay, 30 nm CuO NPs were found to have more antibacterial activity on standard and clinical strains than 60 nm CuO NPs. On the other hand, using MTT, apoptosis, and gene expression method, 30 nm nanoparticles were found to have more anti-cancer potential than 60 nm CuO NPs.
    Conclusions: Our findings implicate CuO-NPs to possess antimicrobial and anti-cancer effects and more significant potential in smaller sizes, suggesting their pharmaceutical and biomedical capacity.

    Abstract Sarcoidosis is a worldwide inflammatory disorder of unknown etiology that is characterized by the formation of non-caseating immune granulomas in involved organs,most commonly in the lungs and eyes. Although clinical manifestations of sarcoidosis depend on the organs involved, the most common symptoms include fatigue, fever, weight loss, eye pain, dyspnea, and chest pain. Sarcoidosis usually undergoes spontaneous regression, yet its chronic form progressively threatens the involved organs through the induction of fibrotic damage. Despite decades of medical research, the etiology of sarcoidosis still remains unclear. Nevertheless, a combination of contributors, including genetic factors, environmental exposures, and microbial agents, is believed to trigger the inflammatory state observed in this disease. Furthermore, a highly polarized Th1 and Th17 response with diminished immunomodulatory mechanisms constitute the most significant immunological event associated with this disorder. Indeed, sarcoid granulomas, which consist of highly activated antigen-presenting cells (APCs) and lymphocytes, maintain a robust specialized niche to facilitate antigen presentation and exaggerated immune responses. Both the unknown etiology and multisystem nature of the disease have hampered the development of specific therapeutics and definitive diagnostic assays for sarcoidosis. Consequently, its diagnosis and treatment still represent a challenging task for clinicians. In this article, we aim to summarize contemporary findings of sarcoidosis and its etiology, pathogenesis, and treatment.
