The inflammaging concept was introduced in 2000 by Prof. Franceschi. This was an evolutionary or rather a revolutionary conceptualization of the immune changes in response to a lifelong stress. This conceptualization permitted to consider the lifelong proinflammatory process as an adaptation which could eventually lead to either beneficial or detri...

Mitochondria are vital organelles with a central role in all aspects of cellular metabolism. As a means to support the ever-changing demands of the cell, mitochondria produce energy, drive biosynthetic processes, maintain redox homeostasis, and function as a hub for cell signaling. While mitochondria have been widely studied for their role in disea...

Mitochondrial dysfunction at birth predicts bronchopulmonary dysplasia (BPD) in extremely low birth weight (ELBW) infants. Recently, nebulized thyroid hormone (TH), given as triiodothyronine (T3) was noted to decrease pulmonary fibrosis in adult animals through improved mitochondrial function. We hypothesized that TH may have similar effects on hyp...

Muskelerkrankungen umfassen hereditäre genetische und erworbene Erkrankungen, welche sowohl im Kindes- als auch im Erwachsenenalter auftreten. Bei den unterschiedlichen Muskelerkrankungen kann es ultrastrukturelle Besonderheiten geben, welche helfen, die Erkrankung weiter einzugrenzen. Spezifische Veränderungen der Sarkomerenstruktur helfen bei der...

Aging is associated with metabolic decline in skeletal muscle, which can be delayed by physical activity. Moreover, both lifelong and short-term exercise training have been shown to prevent age-associated fragmentation of the mitochondrial network in mouse skeletal muscle. However, whether lifelong endurance exercise training exerts the same effect...

Due to the interrupted blood supply in cerebral ischemic stroke (CIS), ischemic and hypoxia results in neuronal depolarization, insufficient NAD+, excessive levels of ROS, mitochondrial damages, and energy metabolism disorders, which triggers the ischemic cascades. Currently, improvement of mitochondrial functions and energy metabolism is as a vita...

Transfer of healthy mitochondria from mesenchymal stem cells (MSCs) to ischemic neurons represents a potent stroke therapeutic. MSCs were grown under ambient conditions (nMSCs) or a metabolic switching paradigm by alternating galactose and glucose in medium (sMSCs) and then assayed for oxygen consumption rates using the Seahorse technology. Subsequ...

In this review we trace the passage of fundamental ideas through 20th century cancer research that began with observations on mustard gas toxicity in World War I. The transmutation of these ideas across scientific and national boundaries, was channeled from chemical carcinogenesis labs in London via Yale and Chicago, then ultimately to the pharmace...

Cancer stem-like cells (CSCs) are critically involved in cancer metastasis and chemoresistance, acting as one major obstacle in clinical practice. While accumulating studies have implicated the metabolic reprogramming of CSCs, mitochondrial dynamics in such cells remain poorly understood. Here we pinpointed OPA1high with mitochondrial fusion as a m...

Metformin is the most common anti-diabetic drug and a promising therapy for disorders beyond diabetes, including Rett syndrome (RTT), a rare neurologic disease characterized by severe intellectual disability. A 10-day-long treatment rescued aberrant mitochondrial activity and restrained oxidative stress in a female RTT mouse model. However, this tr...
