The critical role of mesenchymal stromal/stem cell therapy in COVID-19 patients: An updated review.

New coronavirus disease 2019 (COVID-19), as a pandemic disaster, has drawn the attention of researchers in various fields to discover suitable therapeutic approaches for the management of COVID-19 patients. Currently, there are many worries about the rapid spread of COVID-19; there is no approved treatment for this infectious disease, despite many efforts to develop therapeutic procedures for COVID-19. Emerging evidence shows that mesenchymal stromal/stem cell (MSC) therapy can be a suitable option for the management of COVID-19.

Metformin in combination with genistein ameliorates skeletal muscle inflammation in high-fat diet fed c57BL/6 mice.

Although the beneficial effects of metformin (MET) and genistein in ameliorating inflammation have been elucidated, their combined impacts on skeletal muscle inflammation have not been clearly understood. This study aimed to examine the possible preventive effect of MET in combination with genistein on skeletal muscle inflammation in high-fat diet (HFD) fed C57BL/6 mice. Fifty C57BL/6 male mice were fed on an HFD for 10 weeks.

Novel insights into the interaction between long non-coding RNAs and microRNAs in glioma.

Glioma is the most common brain tumor of the central nervous system. Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been identified to play a vital role in the initiation and progression of glioma, including tumor cell proliferation, survival, apoptosis, invasion, and therapy resistance. New documents emerged, which indicated that the interaction between long non-coding RNAs and miRNAs contributes to the tumorigenesis and pathogenesis of glioma.

Critical review of Epstein-Barr virus microRNAs relation with EBV-associated gastric cancer.

Epstein-Barr virus (EBV)-associated gastric cancer (EBVaGC) is regarded as the most prevalent malignant tumor triggered by EBV infection. In recent years, increasing attention has been considered to recognize more about the disease process's exact mechanisms. There is accumulating evidence that showing epigenetic modifications play critical roles in the EBVaGC pathogenesis.

The effects of natural compounds on wound healing in Iranian traditional medicine: A comprehensive review.

Wounds are physical and anatomical disruption in healthy skin and represent an important healthcare concern around the world. Wound healing is a complex and dynamic cascade of cellular and molecular interactions which include four main phases: hemostasis, inflammatory, proliferative, and remodeling. Therefore, some pharmacological activities such as anti-inflammatory, antioxidant, and antimicrobial activities can play a key role in the process of wound healing.

Critical roles of long noncoding RNAs in breast cancer.

Breast cancer is a major clinical challenge that affects a wide range of the female population and heavily burdens the health system. In the past few decades, attempts have been made to understand the etiology of breast cancer, possible environmental risk factors, and the genetic predispositions, pathogenesis, and molecular aberrations involved in the process. Studies have shown that breast cancer is a heterogeneous entity; each subtype has its specific set of aberrations in different cell signaling pathways, such as Notch, Wnt/β-catenin, transforming growth factor-β, and mitogen-activated protein kinase pathways.

MicroRNAs in breast cancer: Roles, functions, and mechanism of actions.

Breast cancer is one of the most lethal malignancies in women in the world. Various factors are involved in the development and promotion of the malignancy; most of them involve changes in the expression of certain genes, such as microRNAs (miRNAs). MiRNAs can regulate signaling pathways negatively or positively, thereby affecting tumorigenesis and various aspects of cancer progression, particularly breast cancer.

Multiple functions of p27 in cell cycle, apoptosis, epigenetic modification and transcriptional regulation for the control of cell growth: A double-edged sword protein.

The cell cycle is controlled by precise mechanisms to prevent malignancies such as cancer, and the cell needs these tight and advanced controls. Cyclin dependent kinase inhibitor p27 (also known as KIP) is a factor that inhibits the progression of the cell cycle by using specific molecular mechanisms. The inhibitory effect of p27 on the cell cycle is mediated by CDKs inhibition.

Multiple Functions of Long Non-Coding RNAs in Oxidative Stress, DNA Damage Response and Cancer Progression.

In addition to aberrant alternation of transcriptome, it is now suggested that dysregulation of the non-coding transcripts, particularly long non-coding RNAs (lncRNAs), which comprise the majority of the genome, is contributed to cancer initiation and progression. As the result of recent huge efforts, the possible roles of numerous lncRNAs in the human cancers were characterized, as well as various strategies with inhibitory effects to target these transcripts on the transformed cells. Moreover, DNA damage response (DDR) pathway is a complex regulatory network responsible for the identification of disruptions in DNA structure, integrity and stability- it is reported to be associated with the up-regulation and down-regulation of lncRNAs.
