How does m1A contribute to stem cell fate determination in the stem cell niche? 


Best insight from top research papers

m1A contributes to stem cell fate determination in the stem cell niche through its role in gene expression regulation and epigenetic/transcriptional regulatory mechanisms. The levels of m1A in mRNA are associated with translation efficiency and can affect the balance between self-renewal and differentiation in stem cells . Additionally, m1A alteration patterns have been shown to be significantly related to tumor microenvironment (TME) complexity and immune cell infiltration in kidney renal clear cell carcinoma (KIRC) and pancreatic adenocarcinoma (PAAD) . Furthermore, m1A modification-related patterns have been identified in glioma, and differences in survival prognosis, stemness, genomic heterogeneity, TME, and immune cell infiltration have been observed between different clusters . These findings suggest that m1A plays a crucial role in stem cell fate determination by influencing gene expression, TME, and immune cell infiltration.

Is there any antibody regulates M1 and M2 balance?5 answersThere is evidence that antibodies can regulate the balance between M1 and M2 macrophages. In the study by R Qu et al., it was found that the p38MAPK-MEF2C axis plays a role in modulating the homeostasis of M1/M2 macrophage polarization in experimental autoimmune uveitis (EAU). Another study by Federica Raggi et al. showed that the triggering receptor expressed on myeloid cells (TREM)-1, an immunoregulatory receptor, can reverse the M2-polarizing effect of hypoxia and promote a M1-skewed phenotype in macrophages. Additionally, the study by Hong Zhen et al. demonstrated that vitamin A (VitA) and vitamin D (VitD) can influence macrophage polarization, with moderate dosages of VitA or VitD having the most significant impact. These findings suggest that antibodies and certain molecules, such as TREM-1 and vitamins, can regulate the balance between M1 and M2 macrophages.
How m6A regulate glioma stem cells?5 answersm6A modification plays a crucial role in regulating glioma stem cells (GSCs). GSCs are known to be highly chemo-radioresistant and have a high capacity for invasion. The RNA demethylase ALKBH5 has been found to increase radioresistance in GSCs by regulating homologous recombination (HR). Decreased m6A levels, caused by decreased METTL3 and increased FTO levels, have been observed in glioma tissue. Increasing m6A levels in U251 cells through overexpression of METTL3 led to reduced migration and proliferation ability. GSCs from different subtypes of glioblastoma share a set of transcripts that exhibit m6A loss and increased protein translation during differentiation. miRNAs have been found to induce loss of m6A and increase protein translation during GSC state transition. m6A also plays a role in the regulation of cancer stem cell differentiation.
How do changes in the RNA modification landscape of the stem cell niche contribute to aging?5 answersChanges in the RNA modification landscape of the stem cell niche contribute to aging by affecting the epigenetic regulation of stem cell function. Epigenetic changes, such as alterations in histone modifications and DNA methylation, can lead to changes in gene expression programs, ultimately resulting in age-related phenotypes of cells. The epigenome plays a crucial role in regulating stem cell fate decisions, and age-related changes in the epigenome can impact stem cell activity. Additionally, transcriptional alterations, including changes in splicing, long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and transposable elements, have been observed with aging and may contribute to the functional decline of cells and tissues. Understanding the role of RNA modifications and epigenetic regulation in stem cell aging could provide insights into potential interventions to delay aging and extend health-span.
What are the roles of EGFR signaling in the stem cell niche?5 answersEGFR signaling plays important roles in the stem cell niche. It is involved in the regulation of stem cell behavior, including proliferation, differentiation, and survival. In planarians, EGFR signaling is essential for the maintenance and expansion of neoblasts, the proliferative stem cells responsible for tissue homeostasis and regeneration. In Drosophila testes, EGFR signaling controls the interaction of cyst stem cells (CySCs) with the niche, which is important for the regulation of CySC differentiation and organization of the niche that supports germline stem cells (GSCs). Additionally, EGFR signaling has been shown to enhance neural stem cell migration, proliferation, and survival. These findings highlight the crucial role of EGFR signaling in the regulation of stem cell behavior and niche organization in different organisms.
Do changes in the m6A landscape lead to stem cell niche aging?4 answersChanges in the m6A landscape have not been directly addressed in the provided abstracts. However, the abstracts do discuss the role of the stem cell niche in aging and its impact on stem cell function. The niche, which is the microenvironment that supports stem cells, undergoes functional changes with age, including alterations in cellular components and extracellular factors. These changes in the niche can contribute to the decline in stem cell number and activity, leading to compromised tissue homeostasis and regeneration in older individuals. While the abstracts do not specifically mention the m6A landscape, they provide insights into the importance of the stem cell niche in stem cell aging. Further research is needed to determine the specific role of m6A modifications in the aging of the stem cell niche.
What is the cell fate of keratocyte?1 answersKeratocytes, also known as fibroblasts, are mesenchymal-derived cells of the corneal stroma. They are normally quiescent but can transition into repair phenotypes following injury. The interaction between corneal epithelial cells and keratocytes plays a crucial role in corneal wound healing and repair outcomes. Factors derived from the corneal epithelium, as well as the integrity of the epithelial substratum, influence the keratocyte response and determine whether corneal repair will be regenerative or fibrotic in nature. Adult human corneal keratocytes, when challenged in the chick embryonic environment, can differentiate into cranial neural crest derivatives, contributing to various tissues. In the event of corneal injury or trauma, keratocytes near the injured area differentiate into active, synthesizing cells and rapidly replace damaged stromal matrix. Murine corneal keratocytes express MHC class I molecules and can present antigens to CD4+ and CD8+ T cells, providing both antigen-specific and costimulatory signals. Human turbinate mesenchymal stem cells can be cultured in a keratocyte differentiation medium to differentiate into biocompatible keratocyte progenitor cells.
