Stress Protein Expression in Ampelisca abdita (Amphipoda) Exposed to Sediments from San Francisco Bay

摘要

Stress proteins (heat shock proteins, hsps) form part of the cellular protein repair system, and are induced by a wide variety of stressors. To determine their suitability as tools for assessing sublethal sediment toxicity, we measured levels of members of the stress protein families hap60 and hsp70 in benthic estuarine amphipods (Ampelisca abdita) exposed to sediments from 23 different sampling sites in San Francisco Bay for 10d. Concentrations of sediment-associated xenobiotics were determined.
