Expression levels of innexin family members in the adult testes and ovary.
Affymetrix microarray technology has been used to monitor the expression levels of most of the Drosophila genome in different tissues and at different developmental stages (Chintapalli et al, 2007)(GEO database). The measured signal from the inx6 probes are generally so low that it is ambiguous whether the transcript is present or absent. inx6 transcript is most strongly detected in the adult (Adult testes chart). The corresponding tissue in females has no detectable inx6 transcription (Adult ovary chart). inx6 transcript is detected in the adult testes when mRNA is retrieved specifically from the tissue, not when mRNA is recovered from the whole animal (Adult whole body chart)...so, it is unlikely that there are other tissues expressing much Inx6 in the adult. Small, quantifiable, amounts of inx6 are found at other developmenal stages (Larval fat body chart).
