The orange-spotted grouper Epinephelus coioides is a protogynous hermaphroditic fish, but the physiological basis of its sex change remains largely unknown. In the present study, the 2-year-old orange-spotted grouper was induced to change sex precociously by oral administration of 17alpha-methyltestosterone (MT, 50 mg/Kg diet, twice a day at daily ration of(More)
Environmental estrogens, such as bisphenol A (BisA) and nonylphenol (NP), have been shown to affect the estrogen receptor (ER) expression and induce male reproductive abnormalities. To elucidate molecular mechanisms of action of xenoestrogenic chemicals on the expression of estrogen receptors in the testes of Nile tilapia (Oreochromis niloticus), three(More)
Insulin-like growth factor (Igf) is the key regulator for development, growth, and reproduction. In most vertebrate species, the Igf family has two forms: Igf1 and Igf2. A novel form of Igf, termed Igf3, was recently discovered in fish. In the present study, we isolated igf3 from the orange-spotted grouper (Epinephelus coioides). The orange-spotted grouper(More)
We present the complete mitochondrial genome of the Anabas testudineus in this study. The mitochondrial genome is 16,603 bp in length and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The nucleotide compositions of the light strand are 29.40% of C, 28.63% of A, 25.79% of T, and 16.18% of G. With the exception of(More)
The complete mitochondrial genome of the Hemibagrus guttatus was presented in this study. The mitochondrial genome is 16,523 bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The gene order and composition of H. guttatus mitochondrial genome was similar to that of most other vertebrates. The nucleotide(More)
We present the complete mitochondrial genome of the Hemibagrus wyckioides in this study. The mitochondrial genome is 16,525 bp in length and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. Its mitochondrial gene order and composition are similar to that of most other vertebrates. The nucleotide compositions of the(More)
We present the complete mitochondrial genome of Protonibea diacanthus in this study. The mitochondrial genome is 16,535 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. All of them are encoded on the heavy strand except ND6 and 8 tRNA genes on the light strand. The nucleotide compositions of the light(More)
Ancherythroculter lini is the endemic species of fish in China. In this study, we determined the complete mitochondrial genome of Ancherythroculter lini using the next-generation sequencing (NGS). The total length of the complete mitochondrial genome is 16 616 bp which consists of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs genes, and a(More)
