Preface
Studies haveidentified important families ofproteins (denoted:heat shock or
stress proteins, Hsps) which display an enhanced expression in response to
heat shock or other physiological stresses. Besidesthe characterization of the
genes encoding Hsp and the mechanisms of their induction, recent studies
have concentrated on the function of these proteins. It was shown that the
expression of Hsp protects the cell against different types of aggressions.In
addition,Hsp can regulate essential biochemicalprocesses in unstressed cells.
For example, members of the Hsp60 and Hsp70 families act as ATP-binding
proteins allowing the folding of nascent or denatured proteins as well as the
assembly or disassemblyofproteincomplexes.These observationshaveled to
the discovery of the molecular chaperone concept (Ellis and Hemmingsen
1989).
Amongst the proteins whose expression is up-regulated by heat shock
or other types of stresses are the small stress proteins also denoted (sHsps,
sHsp or sHSP).Small stress proteins encompass a large numbers of related
proteins which are represented in virtually all organisms, including prokary
otes. These polypeptides share a structural domain, often referred to as the
a-crystallin domain, common to the lens protein alpha-crystallin (Ingolia
and Craig 1982;Wistow 1985).In addition to being increased in response to
several types ofstresses, the Hsp levelisalso upregulatedduring development
and correlates with the differentiation and oncogenic status of the cell. In
spite ofthe fact that sHsp can confer cellular protection againststresses,their
molecularfunction has remainedenigmaticforyears.Recently,majorfindings
have clarified this point. First, it has been shown that an ATP-independent
chaperone activity is associated to sHsp (Jacob and Buchner 1993).Asecond
important observation concerns the ability of sHsp to form large oligomers
which interact with misfolded polypeptides. These structures probably act
as reservoirs of folding intermediates that are subsequently presented to the
ATP-dependent chaperones (Hsp70 and other co-chaperones) (Ehrnsperger
et al. 1997; Lee et al. 1997). sHsp have therefore been called the "forgotten
chaperones".
In addition to their protein chaperone property,several otherobservations
have contributed to the renewed interest in sHsp.For example, human Hsp27
isexpressedin numerous cancer cellsand induces protection against avariety
of toxic chemicals used in chemotherapy. Hsp27 and aB-crystallin are also
expressed in several pathological situations, such as neurodegenerative dis-

eases.Moreover,amutation in aB-crystallin has been shown tobe responsible
foraspecial type ofmyopathy.Recentdata also suggest homeostaticfunctions
of sHsp at the levelof signal transduction,growth,differentiation and trans
formation processes. Anotherimportantcluewasthe recent finding thatsHsp
can protect against cellsuicide or"apoptosis"(Arrigo 1998,2000).
This book is the first one to be devoted only to small stress proteins. It
surveys the current knowledge concerning the expression and function of
sHsp in differentorganisms rangingform prokaryotesto human,except plant
sHsp which are not described here.Each chapter givesan overview of a spe
cificsubjectarea and includes currentresults from each author's laboratoryas
wellas a overviewof future research directions.This bookwillbe ofvalue to
researchers and graduate students interested in the fieldof cellstress biology,
rangingfrom the molecularto clinical level.
The book is organized in several parts describing different biological
systemsthatarecurrentlyusedtoanalyzethe expressionand function ofsHsp.
The first section of the book, which contains two chapters, deals with sHsp
genetic diversity. The first chapter provides an overview of the complex evo
lutionarydiversityofsHsps,particularlyprokaryoticsHspwhich arenowcon
sideredasancestors of eukaryotic sHsps.The second chapter deals with sHsp
diversity in a desert fish model. The second section of the book is related to
the function and expression of sHsp in different eukaryote models. It begins
with a chapter describing the chaperone activity of sHsp.Then, sHsp from C.
elegans,Drosophila and different mammaliansystems are presented.The third
section ofthe bookcontains three chapterswhich describe pathologicalstates
associated with sHsp expression and gene therapyapproaches aimed at mod
ulating sHsp levelof expression.

strong interest in publishingthis book.
In this book, smallstressproteins (cognate orstressinducedandabbreviated
sHsp,sHsps or sHSPdepending the authors) are defined as those proteinspos
sessing the so-called a-crystallinprotein domain. The name usedfor individual
sHsp is HspXX where xx corresponds to the two first digits ofthe apparent
molecular weight, excluding aA and aB-crystallins which are called by their
own name.
