Mitophagy occurs exclusively in the mitochondrial organ, itself considered one of the types of autophagy, and plays a very specific role in cellular functions and controlling tissue expansion. So, knowing this process as much as possible can help us understand many of the cell processes, especially the cell aging process, and the pathways that cause physiological diseases. In the process of mitophagy in the yeast Saccharomyces cerevisiae, three genes are directly involved, namely ATG 11, ATG 32, and ATG 8. This process has been researched for many years, but winning the 2016 Nobel Prize in Physiology for his discoveries of mechanisms for Autophagy by Yoshinori Ohsumi caused the world's attention to this cellular mechanism. In recent years, the Saccharomyces cell model has received a lot of attention in understanding the process of cell aging and chronic diseases such as type 2 diabetes, Parkinson's, Alzheimer's, and many types of cancer, and this article reviews the importance of the above genes and specifically examines the pathway in cervical Saccharomyces. The specific Autophagy of each organelle can help cure painful and chronic diseases such as type 2 diabetes, Parkinson's, Alzheimer's, and many types of cancer. They hope that by finding the mechanisms, Autophagy can make it more active or keep it active until the end of life, and in this way, it can cure these diseases or at least help cure a lot. This review article attempts to introduce and overview the role of key genes in the process.

The use of medicinal plants in the treatment of diseases has a long history dating back to the presence of humans on earth. Cancer has almost been an incurable disease, and among the various cancers, breast cancer is the most common type of cancer among women and imposes an enormous burden on patients. Although medical and surgical solutions have been proposed for the disease, it has not been successful enough to treat the disease in many patients. In recent years, more studies have been done on the effects of medicinal plants on breast cancer, and scientists are trying to find the exact mechanisms of action for these plants to find effective ways for controlling cancer cell growth. This article focuses on P53 and MDM2, two very important genes involved in regulation of cell growth and proliferation both in cancer and normal tissue, and we also gathered the list of natural compounds targeting the MDM2-p53 pathway. Our results provide a list of plant families that can influence this pathway and have great potential in designing treatments against cancers that encompass deregulation of the MDM2-p53 pathway.

Wound healing is a complex biological process in which many molecules, including microRNA molecules, play an essential role in its regulation. It is well-established that reducing miR-155 expression can accelerate wound healing. This study investigated the effect of using nanoparticles loaded with vitamin C on miR-133, collagen I, and III expressions. In this study, first, nanoparticles of albumin protein were produced and then loaded with vitamin C. 3T3 mouse fibroblast cells were affected by these nanoparticles, and cell behavior was investigated to evaluate the toxicity and appropriate doses. In addition, the expression of collagen I and III genes was studied. The results showed that nanoparticles containing vitamin C in 20 µg/ml concentration had a positive effect on collagen I and III expressions compared to the control group. Moreover, we observed a decrease in the expression of miR-133 in comparison to the control group. Therefore, according to the results of this study, it can be argued that nanoparticles containing vitamin C can significantly decrease the expression of the miR-133 gene and lead to collagen I and III gene overexpression in fibroblasts cells, which is directly effective in wound healing.

Mesenchymal stem/stromal cells (MSCs) as one of the most important types of adult stem cells secrete a variety of immunomodulatory cytokines. However, their immunomodulatory features strongly depend on the molecular cross-talk between cells and the surrounding microenvironment. Hence, some strategies were proposed to empower their beneficial effects during cell-therapeutic procedures to avoid confusing results. Licensing the cells with chemical compounds could be considered as one of the most applicable methods for induction of anti-inflammatory status in the cells. Human chorionic gonadotropin (hCG) is a pregnancy related hormone which has been shown to be essential for the establishment of a successful pregnancy. HCG supports the implantation of fetus in the maternal endometrium, due to its immunomodulatory effects. Moreover, the regulatory role of hCG has been previously mentioned in case of some autoimmune-based diseases. In the present study, the capacity of this hormone for induction of different immune-encountered genes expression was examined in primary cultures of human adipose tissue derived mesenchymal stem cells (Ad-MSCs). In this regard, Ad-MSCs were exposed to 10 IU of hCG for 72 hours. Molecular studies via quantitative Real-time PCR (qRT-PCR) experiments were performed to detect gene expression modifications based on the application of SYBR Green as the fluorescent dye and in comparison to the RPLP0 as the housekeeping gene. Results confirmed that hCG significantly upregulated TSG-6, TGF-β1, IL-1β and IL-6 expression levels comparing with the control group, while it downregulates COX-2 expression, and had no statistically significant effects on IL-10 andTDO2. In conclusion, priming Ad-MSCs with hCG may enhance the proliferation and immunoregulatory potential of these cells, although it needs further investigations to reveal involved molecular pathways.

For 50 years, the term gene is synonymous with regions of the genome gene that coding by mRNAs and translate to protein. nonetheless, Genome wide Recent studies have revealed that regulating gene expression through degradation or translational inhibition of their point mRNAs and thus attend in a wide variety of physiological and pathological cellular processes including: development, cell proliferation, differentiation, and apoptosis pathways by thousands of regulatory non coding RNA such as lncRNAs and microRNAs. According to a recent survey, it is known this RNAs have vital role in regulation cellular pathways at transcriptional, posttranscriptional and epigenetic levels. These noncoding genes are often aberrantly expressed in a variety of human cancers. However, the biological functions of most ncRNAs remain largely in doubt. In this review, we proved that a remarkable part of the genetic etiology of cancer is imposed by noncoding regulatory sequences. The purpose of this review is aimed to give an outlook of using of noncoding RNA as diagnostic markers and therapeutic targets. These observations emphasized that the recognition of coding genes and Research continued evolution and function of non-coding RNAs for a comprehensive understanding human complex diseases like cancer are essential.

Mesenchymal stem cells (MSCs) could differentiate into various types of tissues. These cells serve as a backup for the regeneration and repair of tissues or cells after injury. A skin wound is defined as an injury to the skin that needs to be restored. All types of cells in skin especially mesenchymal stem cells play important role in wound healing process. In particular, paracrine signaling of MSC regulates the cellular responses at the wound site leading to reduction of inflammation, stimulation of angiogenesis and induction of cell migration and proliferation. Because of these abilities, MSCs are one of the most common stem cells for cell therapy in wound healing. This review focuses on the role of MSCs on wound healing process. In addition, major phases of wound repair and challenges of cell therapy are discussed.
