In human cell lines, for example, they were shown to compose ~10% of the total proteome mass 6.Ĭhaperones have been grouped into families based on their molecular mass, common domains, protein structure similarity, and common function 1. In accordance with their fundamental roles, chaperones are abundant proteins. Across species, they promote de novo protein folding and protein maturation 1, protein translocation 2, protein-complexes assembly and disassembly 3, protein disaggregation and refolding 4, and protein degradation 5. Similar content being viewed by othersĬhaperones are highly conserved molecular machines that control cellular protein homeostasis (proteostasis). In this work, we expand the known functional organization of de novo versus stress-inducible eukaryotic chaperones into a layered core-variable architecture in multi-cellular organisms. Analysis of human organ development and aging brain transcriptomes reveals that these functional networks are established in development and decline with age. Together with variable chaperones, they form tissue-specific functional networks. Core chaperones are significantly more abundant across tissues and more important for cell survival than variable chaperones. We demonstrate via a proteomic analysis that the muscle-specific signature is functional and conserved. Through computational analyses of large-scale tissue transcriptomes, we unveil that the chaperone system is composed of core elements that are uniformly expressed across tissues, and variable elements that are differentially expressed to fit with tissue-specific requirements. Yet, the organization of the chaperone system across physiological human tissues has received little attention. I learned little that I didn’t already know about Hollywood in the Twenties, but I enjoyed Lulu in Hollywood.The sensitivity of the protein-folding environment to chaperone disruption can be highly tissue-specific. In it she gives some insight into several actors and actresses she knew well, including Humphrey Bogart, Marion Davies (mistress of publisher William Randolph Hearst), Lilian Gish, Greta Garbo, W.C.Fields, and others. Having satisfied myself that The Chaperone was almost entirely fiction, I finished Louise Brooks’ memoir which continued into the sixties. She found love in New York and returned home to Kansas at the end of the summer, but never established a dance school. Moriarty’s character was thirty-six but not stocky, and she was not the least interested in Ted Shawn, the dance instructor, or in dance. Using that little bit, Moriarty crafted a person with a different name. ”Īnd that’s about all Louise Brooks says of her chaperone. Mills’ provincialism because she shared my love of the theatre. Most of the students were females from the Middle West, to which, like my chaperon, Alice Mills, they would return to establish Denishawn schools. She agreed to accompany me on the train and live with me in New York. ' finally overcame his strong objection to sending a little fifteen-year-old girl away from her home alone by finding me a chaperon, Alice Mills, a stocky, bespectacled housewife of thirty-six who, having fallen idiotically in love with the beautiful Ted Shawn at first sight, decided to study dance with him. She mentions going to New York in 1922 to study at a famous dance studio, Denishawn, and that she was accompanied by a chaperone.

Her memoirs cover her early years only superficially and that’s the part that The Chaperone covers. Mary Louise Brooks was born in 1906 and died in 1985.

So I got a copy of the memoirs of Louise Brooks, Lulu in Hollywood, published in 1974. But I was curious, as I am whenever I read historical fiction–how much of it was true? I enjoyed Laura Moriarty’s book, The Chaperone, a fictionalized story about the silent film star Louise Brooks.
