Toward a Mechanistic Understanding of Poly- and Perfluoroalkylated Substances and Cancer.

Cancers (Basel) 2022 Jun 14;14(12). Epub 2022 Jun 14.

Department of Comparative Biosciences, University of Illinois, Urbana-Champaign, Urbana, IL 61802, USA.

Poly- and perfluoroalkylated substances (PFAS) are chemicals that persist and bioaccumulate in the environment and are found in nearly all human populations through several routes of exposure. Human occupational and community exposure to PFAS has been associated with several cancers, including cancers of the kidney, testis, prostate, and liver. While evidence suggests that PFAS are not directly mutagenic, many diverse mechanisms of carcinogenicity have been proposed. Read More

A mitochondrial unfolded protein response inhibitor suppresses prostate cancer growth in mice via HSP60.

J Clin Invest 2022 Jun 2. Epub 2022 Jun 2.

Roswell Park Comprehensive Cancer Center, Buffalo, United States of America.

Mitochondrial proteostasis, regulated by the mitochondrial unfolded protein response (UPRmt), is crucial for maintenance of cellular functions and survival. Elevated oxidative and proteotoxic stress in mitochondria must be attenuated by the activation of ubiquitous UPRmt to promote prostate cancer (PCa) growth. Here we show that the two key components of the UPRmt, heat shock protein 60 (HSP60, a mitochondrial chaperonin) and caseinolytic protease (ClpP, a mitochondrial protease) were required for the development of advanced PCa.

Topological dynamics of an intrinsically disordered N-terminal domain of the human androgen receptor.

Protein Sci 2022 06;31(6):e4334

Medical Systems Biophysics and Bioengineering, Leiden Academic Centre for Drug Research, Faculty of Science, Leiden University, Leiden, The Netherlands.

Human androgen receptor contains a large N-terminal domain (AR-NTD) that is highly dynamic and this poses a major challenge for experimental and computational analysis to decipher its conformation. Misfolding of the AR-NTD is implicated in prostate cancer and Kennedy's disease, yet our knowledge of its structure is limited to primary sequence information of the chain and a few functionally important secondary structure motifs. Here, we employed an innovative combination of molecular dynamics simulations and circuit topology (CT) analysis to identify the tertiary structure of AR-NTD. Read More
