AI Article Synopsis

  • Recent progress shows that aging is a universal aspect of life, but understanding its molecular mechanisms poses significant challenges in biology.
  • Yeast (Saccharomyces cerevisiae) serves as an important model for aging research due to its simplicity, which allows for clearer studies compared to humans.
  • This review discusses current knowledge of aging in yeast and emphasizes the potential of high-throughput systems and systems biology approaches to enhance our understanding of the aging process.

Article Abstract

Progress in the last decades indicated that ageing might be a universal fact of life. However, the molecular mechanisms underlying this process remain a major challenge in biology. Our relatively long life span and huge variations in lifestyle make detailed studies of ageing in humans difficult to interpret. In contrast, the relatively simple yeast Saccharomyces cerevisiae (budding yeast) has been a critical model in the field of ageing research for decades. Systems biology has contributed to the ageing field by mapping complex regulatory networks and resolving the dynamics of signal transduction pathways. In this review we first review the current understanding of ageing in yeast, then highlight the recent high-throughput systems and system biology approaches that could be used to further our understanding of ageing in yeast.

Neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses.

Neurobiol Aging

January 2025

Department of Psychology, The Pennsylvania State University,  University Park, PA 16802, United States. Electronic address:

The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related lures.

Extensive research has demonstrated endurance exercise to be neuroprotective. Whether these neuroprotective benefits are mediated, in part, by hepatic ketone production remains unclear. To investigate the role of hepatic ketone production on brain health during exercise, healthy 6-month-old female rats underwent viral knockdown of the rate-limiting enzyme in the liver that catalyses the first reaction in ketogenesis: 3-hydroxymethylglutaryl-CoA synthase 2 (HMGCS2).

Purpose Of Review: The purpose of this review is to summarize the current understanding of cell-autonomous innate immune pathways that contribute to bone homeostasis and disease.

Recent Findings: Germ-line encoded pattern recognition receptors (PRRs) are the first line of defense against danger and infections. In the bone microenvironment, PRRs and downstream signaling pathways, that mount immune defense, interface intimately with the core cellular processes in bone cells to alter bone formation and resorption.

Bone Marrow Adipocytes as Novel Regulators of Metabolic Homeostasis: Clinical Consequences of Bone Marrow Adiposity.

Curr Obes Rep

January 2025

Maine Medical Center Research Institute, Maine Medical Center, 81 Research Drive, Scarborough, ME, 04074, USA.

Purpose Of Review: Bone marrow adipose tissue is a distinctive fat depot located within the skeleton, with the potential to influence both local and systemic metabolic processes. Although significant strides have been made in understanding bone marrow adipose tissue over the past decade, many questions remain regarding their precise lineage and functional roles.

Recent Findings: Recent studies have highlighted bone marrow adipose tissue's involvement in continuous cross-talk with other organs and systems, exerting both endocrine and paracrine functions that play a crucial role in metabolic homeostasis, skeletal remodeling, hematopoiesis, and the progression of bone metastases.

Mitochondria represent pivotal cellular organelles endowed with multifaceted functionalities encompassing cellular respiration, metabolic processes, calcium turnover, and the regulation of apoptosis, primarily through the generation of reactive oxygen species (ROS). Perturbations in mitochondrial dynamics have been intricately linked to the etiology of numerous cardiovascular pathologies, such as heart failure, ischemic heart disease, and various cardiomyopathies. Notably, recent attention has been directed towards the detrimental impact of micro- and nanoplastic pollution on mitochondrial integrity, an area underscored by a paucity of comprehensive investigations.
