Table 3 Distinct mesterolone-induced changes in fiber size and cellular parameters of anterior latissimus dorsi (ALD) and pectoralis major (PM) muscles.
From: Differential response of oxidative and glycolytic skeletal muscle fibers to mesterolone
Parameter | ALD muscle (oxidative fibers) | PM muscle (glycolytic fibers) |
|---|---|---|
Fiber CSA | Unchanged | > 17–33% |
Lesser fiber diameter | Unchanged | > 11–15% |
SCs per 100 fibers | > 1.5–1.9 fold | > 1.9–2.6 fold |
SCs per 1 mm | > 1.6–2.0 fold | > 1.9–2.6 fold |
SC frequency | > 1.5–1.6 fold | > 1.5–1.9 fold |
Surface area of plasmalemma per SC | < 1.6–1.8 fold | < 1.7–2.3 fold |
MN per 100 muscle fibers | Unchanged | > 1.3–1.4 fold |
MN per 1 mm | Unchanged | > 1.3–1.4 fold |
Myonuclear domain | Unchanged | Unchanged |
