		However, if you are talking about the tsunami in the classroom for the first time, it is important to bear in mind the effects of the disaster and subsequent media coverage on your pupils, and we recommend that you give pupils the opportunity to talk openly about their own feelings.
		The following activities are designed to support you in exploring with pupils the impact of the Indian Ocean tsunami on communities in the affected regions.
		If you are revisiting issues raised by the tsunami and exploring the situation a couple of months on, you may want to allow pupils to talk about their feelings again and ask them whether their feelings about the disaster have changed, and if so, why.

	Interrenal steroid 21-hydroxylase in eels: primary structure, progesterone-specific activity and enhanced expression by ACTH -- Li et al. 31 (2): 327 -- Journal of Molecular Endocrinology
		Interrenal steroid 21-hydroxylase in eels: primary structure, progesterone-specific activity and enhanced expression by ACTH
		Functional expression of the cDNA clone in non-steroidogenic COS-1 cells produced a protein with high 21-hydroxylase activity to convert progesterone to 11-deoxycortisterone but not 17alpha-hydroxyprogesterone to 11-deoxycortisol, although the latter is a preferred substrate for mammalian P450c21.
		To examine whether 21-hydroxylated progesterone is actually 17alpha-hydroxylated in the eel interrenal, 11-deoxycorticosterone and (3)H-corticosterone were respectively incubated with the interrenal-containing anterior quarter of the head kidney.

	Synergism with germ line transcription factor Oct-4: viral oncoproteins share the ability to mimic a stem cell-specific activity.
		The adenovirus E1A protein can mimic the activity of this stem cell-specific factor and stimulates Oct-4 activity in differentiated cells.
		Furthermore, we demonstrate that, like E1A, the human papillomavirus E7 oncoprotein also specifically binds to the Oct-4 POU domain.
		Here we characterize the Oct-4-E1A interaction and show that the E1A 289R protein harbors two independent Oct-4 binding sites, both of which specifically interact with the POU domain of Oct-4.
