Mitochondrial Serine Catabolism Maintains Hematopoietic Stem Cell Pool in Homeostasis and Injury

Research Background The maintenance and repair of the hematopoietic system are crucial for the continuation of life and health in an organism. As the foundation of the hematopoietic system, the stability of hematopoietic stem cells (HSCs) is particularly important. The maintenance of the HSC pool relies on intrinsic and extrinsic factors, among whi...

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

Research Background and Objective As individuals age, hematopoietic stem cells (HSCs) progressively accumulate in the bone marrow, exhibiting metabolic resilience under various stress conditions. This metabolic resilience provides an aging advantage for HSCs, enabling them to maintain cell viability even under low metabolic conditions. Although agi...

MGA Deletion Leads to Richter’s Transformation by Modulating Mitochondrial OXPHOS

MGA Deletion Promotes Richter’s Transformation by Regulating Mitochondrial Oxidative Phosphorylation This article mainly focuses on the transformation of chronic lymphocytic leukemia (CLL) into aggressive lymphoma, known as Richter’s Transformation (RT), exploring the function and molecular mechanism of MGA (MAX Gene Associated). MGA is a functiona...

Aging-induced tRNAglu-derived fragment impairs glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization

Aging-induced trnaGlu-derived fragments disrupt glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization Academic Background Mitochondrial cristae are inward protrusions of the inner mitochondrial membrane that undergo significant morphological changes during aging. However, the molecular mechanisms leading to th...

TH17 Cell-Intrinsic Glutathione/Mitochondrial-IL-22 Axis Protects Against Intestinal Inflammation

Intrinsic Glutathione/Mitochondrial-IL-22 Axis in TH17 Cells and Its Protective Mechanism Against Intestinal Inflammation Background Introduction A large amount of reactive oxygen species (ROS) is generated in the intestine, and the role of T-cell antioxidant mechanisms in maintaining intestinal homeostasis remains unclear. This paper studies the i...

A novel protein cytb-187aa encoded by the mitochondrial gene cytb modulates mammalian early development

The New Protein Cytb-187aa Regulates Mammalian Early Development Academic Background Mitochondria are multifunctional organelles that provide energy for cells. In addition to energy supply, they are involved in the regulation of apoptosis, cell signaling, and various biosynthetic pathways. Among these functions, substances within mitochondria can b...

A Missense Variant in AIFM1 Caused Mitochondrial Dysfunction and Intolerance to Riboflavin Deficiency

Missense Mutation in AIFM1 Gene Leads to Mitochondrial Dysfunction and Riboflavin Deficiency Intolerance Research Background Mitochondria are double-membrane organelles found in eukaryotic cells with nuclei, primarily producing adenosine triphosphate (ATP) through oxidative phosphorylation to provide cellular energy. Mitochondria have their own gen...

Development and Application of a Mitochondrial Genetically Encoded Voltage Indicator in Narcosis

Mitochondrial Targeting Application of Genetically Encoded Voltage Indicators (GEVIs) Background and Research Motivation Mitochondria, as the energy factories of eukaryotic cells, play crucial roles in various cellular processes, including bioenergetic conversion, metabolite synthesis, cell survival, calcium storage, and heat production. In organs ...

Alleviating CB2-dependent ER stress and mitochondrial dysfunction improves chronic cerebral hypoperfusion-induced cognitive impairment

Research Overview and Background With the acceleration of global aging, the incidence of ischemic cerebrovascular diseases is also rising significantly. Elderly people over 65 are particularly susceptible to cognitive decline caused by cerebral ischemia, making Chronic Cerebral Hypoperfusion (CCH) a major cause of cognitive impairment and Vascular ...
