The ‘fuzzy’ interactome

Concerns regarding the characterization of the cellular protein–protein interactome have attracted considerable attention lately in TiBS [1–5] and in many publications elsewhere. Mackay et al. [1] claimed that many reports of protein interactions are founded on ‘insufficient data’ and that it is becoming ‘dangerously acceptable’ to conclude that proteins interact based on questionable results and limited methodologies. Chatr-aryamontri et al. [2] defended the importance of protein-interaction databases (e.g.

Cell versus protoplasm: revisionist history

Recent investigations give reason to question anew the historical status of the ‘cell theory’ as the ultimate driving force in the development of our understanding of lifes processes at the most fundamental level. A revisitation of critical research papers and commentaries from the 19th Century shows that the disregarded (and historically maligned) ‘protoplasmic theory of life’ played a more deterministic role in the early advancement of knowledge on cell structure and function.

Reply to “Letter to the editor: ‘Systemic cell theory, protoplasmic theory, and their logic of explanation’”

We recently reported that adrenomedullary chromaffin cells (AMC) from neonatal rats treated with intermittent hypoxia (IH) exhibit enhanced catecholamine secretion by hypoxia (Souvannakitti D, Kumar GK, Fox A, Prabhakar NR. J Neurophysiol 101: 2837-2846, 2009). In the present study, we examined whether neonatal IH also facilitate AMC responses to nicotine, a potent stimulus to chromaffin cells. Experiments were performed on rats exposed to either IH (15-s hypoxia-5-min normoxia; 8 h/day) or to room air (normoxia; controls) from ages postnatal day 0 (P0) to P5. Quantitative RT-PCR analysis revealed expression of mRNAs alpha(3-), alpha(5-), alpha(7-), and beta(2-) and beta(4-)nicotinic acetylcholine receptor (nAChR) subunits in adrenal medullae from control P5 rats. Nicotine-elevated intracellular Ca(2+) concentration ([Ca(2+)](i)) in AMC and nAChR antagonists prevented this response, suggesting that nAChRs are functional in neonatal AMC. In IH-treated rats, nAChR mRNAs were downregulated in AMC, which resulted in a markedly attenuated nicotine-evoked elevation in [Ca(2+)](i) and subsequent catecholamine secretion. Systemic administration of antioxidant prevented IH-evoked downregulation of nAChR expression and function. P35 rats treated with neonatal IH exhibited reduced nAChR mRNA expression in adrenal medullae, attenuated AMC responses to nicotine, and impaired neurogenic catecholamine secretion. Thus the response to neonatal IH lasts for at least 30 days. These observations demonstrate that neonatal IH downregulates nAChR expression and function in AMC via reactive oxygen species signaling, and the effects of neonatal IH persist at least into juvenile life, leading to impaired neurogenic catecholamine secretion from AMC.
