Traceless Regulation of Genetic Circuitry

Advanced Science, EarlyView.
Energy‐based, as opposed to molecular, control offers unprecedented improvements in key circuit parameters. This review summarizes the fundamentals of such traceless switches, categorizes them by trigger modalities, and compares and contrasts distinct advantages as well as shortcomings of each kind.

HSF1: Primary Factor in Molecular Chaperone Expression and a Major Contributor to Cancer Morbidity

Cells, 2020
Heat shock factor 1 (HSF1) is the primary component for initiation of the powerful heat shock response (HSR) in eukaryotes. The HSR is an evolutionarily conserved mechanism for responding to proteotoxic stress and involves the rapid expression of heat ...

Insights into organelle forming RNAs: Diversity, functions and future perspectives

Animal Models and Experimental Medicine, EarlyView.
RNA molecules play crucial roles in the formation and maintenance of cellular structures and organelles. These ‘organelle formation RNAs’ include ribosomal RNAs, paraspeckle‐forming RNAs, nuclear speckle‐forming RNAs, nucleolus‐forming RNAs, and cytoskeleton‐forming RNA.

HSF1 mediated stress response of heavy metals

PLOS ONE, 2018
The heat shock response (HSR) pathway is a highly conserved cellular stress response and mediated by its master regulator HSF1. Activation of the pathway results in the expression of chaperone proteins (heat shock proteins; HSP) to maintain protein homeostasis. One of the genes strongest upregulated upon stress is HSPA1A (HSP72).

Targeting GRP78 and the Proteostasis Network to Break the Therapeutic Ceiling in Neuroendocrine Prostate Cancer

iNew Medicine, EarlyView.
ABSTRACT HSPA5 (also known as GRP78/BiP) is a master regulator of the endoplasmic reticulum (ER) stress response and a key node in the proteostasis network. In neuroendocrine prostate cancer (NEPC), an aggressive, therapy‐refractory lineage that emerges under pressure from androgen receptor (AR) directed therapies, GRP78 is upregulated and co‐opted to ...

Heat shock factor 1 (HSF1) cooperates with estrogen receptor α (ERα) in the regulation of estrogen action in breast cancer cells

eLife, 2021
Heat shock factor 1 (HSF1), a key regulator of transcriptional responses to proteotoxic stress, was linked to estrogen (E2) signaling through estrogen receptor α (ERα).

CRISPR Enabled Precision Oncology: From Gene Editing to Tumor Microenvironment Remodeling

Med Research, EarlyView.
CRISPR technology has progressed from a prokaryotic immune system to a diverse suite of editing platforms, including Cas nucleases, base and prime editors, and RNA‐targeting enzymes. These advances enable precise genomic and epigenomic interventions, high‐throughput functional screening, and immune engineering.

Heat shock factor 1 (HSF1) specifically potentiates c-MYC-mediated transcription independently of the canonical heat shock response

Cell Reports, 2023
Summary: Despite its pivotal roles in biology, how the transcriptional activity of c-MYC is tuned quantitatively remains poorly defined. Here, we show that heat shock factor 1 (HSF1), the master transcriptional regulator of the heat shock response, acts ...

Disarming the Hsp70–Bim Alliance: Small‐Molecule and Peptidic Disruptors of a Chaperone‐Apoptotic Switch in Cancer

ChemistryOpen, EarlyView.
Targeting a nucleotide‐sensitive groove on Hsp70 that binds the Bim BH3 helix, we integrate structures, biophysics, and SAR from peptides, fragments, and phenalene‐dicarbonitrile “wedges.” These disrupt the Hsp70–Bim complex with sub‐µM cellular engagement and in vivo activity while sparing Hsp90/mortalin.
