Upregulation of HAL2 during intestinal metamorphosis. Total RNA isolated from the intestine of animals from premetamorphic stage 54 to the end of metamorphosis (stage 66) was subjected to qRT-PCR analysis for HAL2 gene expression. Note that again HAL2 was found to have little or no expression before or after metamorphosis but was drastically upregulated during metamorphosis.
