High impact information on vtg3

The level of vtg1 mRNA was about 100x and 1000x higher than those of vtg2 and vtg3 mRNAs [1].
The seven vtgs were located in two different chromosomes: one (vtg3) in LG11 and the rest closely linked in LG22, probably arisen from local gene duplication events [1].
Following a brief water exposure (24h) to 2, 5, and 10 ng/L 17alpha-ethynylestradiol (EE2), both vg1and vg3 were upregulated in male liver [2].
The fathead minnow vg3 sequence is the second nucleotide sequence described in teleosts, following the original description of this isoform in zebrafish (Danio rerio) [2].

Associations of vtg3 with chemical compounds

Suppression of vg in female liver following exposure to 50 or 500 ng/L of the synthetic androgen 17beta-trenbolone occurs at similar magnitude for both vg1 and vg3 isoforms [2].
