Abstract
Partial reprogramming by cyclic short-term expression of Yamanaka factors holds promise for shifting cells to younger states and consequently delaying the onset of many diseases of aging. However, the delivery of transgenes and potential risk of teratoma formation present challenges for in vivo applications. Recent advances include the use of cocktails of compounds to reprogram somatic cells, but the characteristics and mechanisms of partial cellular reprogramming by chemicals remain unclear. Here, we report a multi-omics characterization of partial chemical reprogramming in fibroblasts from young and aged mice. We measured the effects of partial chemical reprogramming on the epigenome, transcriptome, proteome, phosphoproteome, and metabolome. At the transcriptome, proteome, and phosphoproteome levels, we saw widescale changes induced by this treatment, with the most notable signature being an upregulation of mitochondrial oxidative phosphorylation. Furthermore, at the metabolome level, we observed a reduction in the accumulation of aging-related metabolites. Using both transcriptomic and epigenetic clock-based analyses, we show that partial chemical reprogramming reduces the biological age of mouse fibroblasts. We demonstrate that these changes have functional impacts, as evidenced by changes in cellular respiration and mitochondrial membrane potential. Taken together, these results illuminate the potential for chemical reprogramming reagents to rejuvenate aged biological systems and warrant further investigation into adapting these approaches for in vivo age reversal.

J Pharmacol Sci 2023; 153:46-54. [PMID: 37524454 DOI: 10.1016/j.jphs.2023.07.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/29/2023] [Accepted: 07/10/2023] [Indexed: 08/02/2023] Open
Abstract
Premature ovarian insufficiency (POI) is a clinical syndrome that declines ovarian function in women. Berberine (BBR) is a compound with anti-inflammatory, antioxidant, and anti-apoptotic activities. However, the role of BBR on POI is still unknown. In this study, we investigated the role of BBR on ovarian function decline by establishing a POI mouse model using cyclophosphamide (CTX) and busulfan (BU). Our results showed that POI was attenuated by BBR, which was evidenced by enhanced body weight and ovarian weight, improved morphology of ovary, increased the number of healthy follicles, decreased the production of atretic follicles and restored serum hormone levels, including estradiol, anti-Müllerian hormone and follicle-stimulating hormone. In addition, we showed that germ cell function markers, mouse vasa homologue (MVH) and octamer-binding transcription factor 4 (OCT4) were enhanced by BBR, at both protein and mRNA levels. Furthermore, our results revealed that BBR inhibited inflammation and oxidative stress by reducing nuclear factor kappa B (NF-κB) and enhancing nuclear factor erythroid 2-related factor 2 (Nrf2) pathways. Taken together, we demonstrate that BBR can effectively improve ovarian function in POI mice, which is mainly mediated by reducing oxidative stress and inflammatory response. Our study also provides new strategy for POI treatment.

Cells 2022; 11:cells11081346. [PMID: 35456025 PMCID: PMC9028986 DOI: 10.3390/cells11081346] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/08/2022] [Accepted: 04/11/2022] [Indexed: 12/13/2022] Open
Abstract
It is now definitively established that a large part of the human genome is transcribed. However, only a scarce percentage of the transcriptome (about 1.2%) consists of RNAs that are translated into proteins, while the large majority of transcripts include a variety of RNA families with different dimensions and functions. Within this heterogeneous RNA world, a significant fraction consists of sequences with a length of more than 200 bases that form the so-called long non-coding RNA family. The functions of long non-coding RNAs range from the regulation of gene transcription to the changes in DNA topology and nucleosome modification and structural organization, to paraspeckle formation and cellular organelles maturation. This review is focused on the role of long non-coding RNAs as regulators of cyclin-dependent kinase inhibitors’ (CDKIs) levels and activities. Cyclin-dependent kinases are enzymes necessary for the tuned progression of the cell division cycle. The control of their activity takes place at various levels. Among these, interaction with CDKIs is a vital mechanism. Through CDKI modulation, long non-coding RNAs implement control over cellular physiology and are associated with numerous pathologies. However, although there are robust data in the literature, the role of long non-coding RNAs in the modulation of CDKIs appears to still be underestimated, as well as their importance in cell proliferation control.
