Exercise training (ExT) improves skeletal muscle health via multiple adaptative pathways. Nrf2 is a principal antioxidant transcription factor responsible for maintaining intracellular redox homeostasis. In this study, we hypothesized that essential responses to ExT and thus beneficial muscle. Experiments were carried out on male wild type (WT) iMS-Nrf2flox/flox inducible muscle-specific (KO) mice, which randomly assigned serve as sedentary controls (Sed) or underwent 3 weeks of treadmill...
Wing polymorphism is a powerful model for examining many aspects of adaptation. The wing dimorphic cricket species, Gryllus firmus, consists long-winged morph with functional flight muscles that capable flight, and two flightless morphs. One (obligately) emerges as an adult vestigial wings muscles. other (plastic) fully-developed but later in adulthood histolyzes its Importantly both morphs have substantially increased reproductive output relative to the flight-capable morph. Much known...
Despite a number of recent reports insect resistance to transgenic crops expressing insecticidal toxins from Bacillus thuringiensis (Bt), little is known about the mechanism these toxins.
