AI Article Synopsis
- The process of in vivo reprogramming using transcription factors Oct4, Sox2, Klf4, and c-Myc (OSKM) shows potential for rejuvenation and regeneration, but carries a risk of tumor development.
- This review explores the transformative effects of in vivo reprogramming on aging and cellular regeneration, emphasizing the double-edged nature of cellular plasticity that can lead to both healing and cancer.
- Understanding how to separate cellular identity, plasticity, and aging during reprogramming could help create safer rejuvenation and regenerative treatments without increasing tumor risks.
Article Abstract
The multistep process of in vivo reprogramming, mediated by the transcription factors (TFs) Oct4, Sox2, Klf4, and c-Myc (OSKM), holds great promise for the development of rejuvenating and regenerative strategies. However, most of the approaches developed so far are accompanied by a persistent risk of tumorigenicity. Here, we review the groundbreaking effects of in vivo reprogramming with a particular focus on rejuvenation and regeneration. We discuss how the activity of pioneer TFs generates cellular plasticity that may be critical for inducing not only reprogramming and regeneration, but also cancer initiation. Finally, we highlight how a better understanding of the uncoupled control of cellular identity, plasticity, and aging during reprogramming might pave the way to the development of rejuvenating/regenerating strategies in a nontumorigenic manner.

Peripubertal antagonism of corticotropin-releasing factor receptor 1 results in sustained changes in behavioral plasticity and the transcriptomic profile of the amygdala.

Peripuberty is a significant period of neurodevelopment with long-lasting effects on the brain and behavior. Blocking type 1 corticotropin-releasing factor receptors (CRFR1) in neonatal and peripubertal rats attenuates detrimental effects of early-life stress on neural plasticity, behavior, and stress hormone action, long after exposure to the drug has ended. CRFR1 antagonism can also impact neural and behavioral development in the absence of stressful stimuli, suggesting sustained alterations under baseline conditions.

Background: Brain ageing is accompanied by the diminution of neuronal plasticity, which is correlated with the inability to respond to loss of memory, various stress-induced stimuli, and increased risk of neurodegenerative disorders. In the recent past, plant based herbal medicines are of interest over synthetic drugs for therapeutic purposes due to lower side effects. The Indian traditional medicine Ayurveda describes several herbal remedies, such as rasayana (elixirs for rejuvenation), to treat many age-related diseases.

Background: Despite the lack of clinically validated strategies for treating spinal cord injury (SCI), combining therapeutic strategies with rehabilitation is believed to promote recovery of motor function; however, current research findings are inconsistent.
Objectives: To explore whether combination therapy involving therapy and rehabilitative training (CIRT) has a synergistic effect on motor function recovery in animal models of SCI.
Methods: We conducted a systematic review and meta-analysis of studies identified in a keyword search of 6 databases and extracted open-field motor scores from the Basso Mouse Scale (BMS) and the Basso, Beattie, and Bresnahan Locomotor Rating Scale (BBB) for meta-analysis using a weighted mean difference (WMD) and 95 % CI.

Melanoma is a devastating form of skin cancer characterized by a high mutational burden, limited treatment success, and dismal prognosis. Although immunotherapy and targeted therapies have significantly revolutionized melanoma treatment, the majority of patients fail to achieve durable responses, highlighting the urgent need for novel therapeutic strategies. Ferroptosis, an iron-dependent form of regulated cell death driven by the overwhelming accumulation of lipid peroxides, has emerged as a promising therapeutic approach in preclinical melanoma models.
