David Dudley Moore (born August 21, 1952) is an American molecular biologist known for his work investigating nuclear hormone receptors. He is a Professor and Chair of the Department of Nutritional Sciences & Toxicology at the University of California, Berkeley. He was a founding editor for the Current Protocols series of laboratory manuals in 1987.
Moore has been a leading figure in the investigation of nuclear hormone receptors, having initially discovered and described many family members. Some of his most significant discoveries are the constitutive androstane receptor (CAR) in 1994, farnesoid X receptor (FXR) in 1995, and the small heterodimer partner (SHP) in 1996. [1] [2] [3] [4] [5]
In 2019 he was elected to the National Academy of Sciences. [1] [6]
Moore was born in Brookline, Massachusetts in 1952, and was adopted by Clinton and Emily Moore from The Home for Little Wanderers. He was raised in Cincinnati, Ohio and graduated from Madeira High School in 1970.
After completing his undergraduate degree at Brown University in Providence, Rhode Island in 1974, [1] he received his Ph.D. in 1979 from the University of Wisconsin–Madison, studying origin of replication sequences in bacteriophage lambda under Frederick Blattner. [7]
Moore began work as a postdoctoral researcher in 1979 in the laboratory of Howard Goodman in the Department of Biochemistry and Biophysics at the University of California, San Francisco, where he studied the genetic sequence of human growth hormone and the DNA binding activity of the glucocorticoid receptor. [8] [9]
Moore joined the faculty of the Department of Genetics at Harvard Medical School in 1981, and became a founding member of the Department of Molecular Biology at Massachusetts General Hospital. [1] There, Moore's research lab investigated the activity of thyroid hormone and its relation to growth hormone expression. In collaboration with P. Reed Larsen, he identified several novel thyroid hormone receptors. [10] [11]
In 1987, Moore, alongside other colleagues including Frederick M Ausbel, established the laboratory manual series Current Protocols in Molecular Biology, which was acquired by Wiley in 1995 and later expanded to include additional titles. [12]
Moore published a series of studies beginning in 1994 identifying and describing the constitutive androstane receptor (CAR), a constitutively active nuclear receptor which senses and responds to endobiotic and xenobiotic substances. [3] [13]
In 1996, Moore and his lab identified the small heterodimer partner (SHP), an orphan nuclear receptor without DNA-binding activity which binds other proteins to regulate their activity. [14] He found that SHP inhibits estrogen receptors as well as retinoid receptors. [4] [15] He later found that SHP regulates the circadian clock in mice. [16]
In 1997, Moore was recruited to the Department of Molecular and Cellular Biology, then headed by Bert W. O'Malley, at Baylor College of Medicine in Houston, Texas. There, he identified the bile acid and xenobiotic ligands of farnesoid X-receptor, an orphan nuclear receptor he had first purified in 1995, and an upstream regulator of SHP. [5] [17] He also identified androstane metabolites and xenobiotics as ligands for CAR during this time. [13] [18]
The discovery of bile acid ligands for FXR led Moore and colleagues to demonstrate a strong link between nuclear hormone receptors and liver disease. He showed that disruption of CAR, FXR, and SHP leads to liver tumors, [19] [20] [21] hepatomegaly, [19] [22] and fatty liver disease. [23] [24]
Moore became professor of the Department of Nutritional Sciences & Toxicology at the University of California, Berkeley in 2020, where he became department chair in 2022. [2]
Moore's h-index is 110 and i10-index is 303, and his publications have been cited over 87,000 times as of August 2023 according to his Google Scholar page. [25]
Moore has received many academic prizes for his work, including the Edwin B. Astwood Award from the Endocrine Society [26] and the Transatlantic Medal from the Society for Endocrinology. [27] Moore was elected to the National Academy of Sciences in 2019 [1] and in 2022 became a fellow at the American Association for the Advancement of Science. [28]
Estrogen receptors (ERs) are a group of proteins found inside cells. They are receptors that are activated by the hormone estrogen (17β-estradiol). Two classes of ER exist: nuclear estrogen receptors, which are members of the nuclear receptor family of intracellular receptors, and membrane estrogen receptors (mERs), which are mostly G protein-coupled receptors. This article refers to the former (ER).
Estrogen receptor alpha (ERα), also known as NR3A1, is one of two main types of estrogen receptor, a nuclear receptor that is activated by the sex hormone estrogen. In humans, ERα is encoded by the gene ESR1.
The bile acid receptor (BAR), also known as farnesoid X receptor (FXR) or NR1H4, is a nuclear receptor that is encoded by the NR1H4 gene in humans.
The liver X receptor (LXR) is a member of the nuclear receptor family of transcription factors and is closely related to nuclear receptors such as the PPARs, FXR and RXR. Liver X receptors (LXRs) are important regulators of cholesterol, fatty acid, and glucose homeostasis. LXRs were earlier classified as orphan nuclear receptors, however, upon discovery of endogenous oxysterols as ligands they were subsequently deorphanized.
In the field of molecular biology, the pregnane X receptor (PXR), also known as the steroid and xenobiotic sensing nuclear receptor (SXR) or nuclear receptor subfamily 1, group I, member 2 (NR1I2) is a protein that in humans is encoded by the NR1I2 gene.
The constitutive androstane receptor (CAR) also known as nuclear receptor subfamily 1, group I, member 3 is a protein that in humans is encoded by the NR1I3 gene. CAR is a member of the nuclear receptor superfamily and along with pregnane X receptor (PXR) functions as a sensor of endobiotic and xenobiotic substances. In response, expression of proteins responsible for the metabolism and excretion of these substances is upregulated. Hence, CAR and PXR play a major role in the detoxification of foreign substances such as drugs.
In the field of molecular biology, nuclear receptors are a class of proteins responsible for sensing steroids, thyroid hormones, vitamins, and certain other molecules. These intracellular receptors work with other proteins to regulate the expression of specific genes, thereby controlling the development, homeostasis, and metabolism of the organism.
Cholesterol 7 alpha-hydroxylase also known as cholesterol 7-alpha-monooxygenase or cytochrome P450 7A1 (CYP7A1) is an enzyme that in humans is encoded by the CYP7A1 gene which has an important role in cholesterol metabolism. It is a cytochrome P450 enzyme, which belongs to the oxidoreductase class, and converts cholesterol to 7-alpha-hydroxycholesterol, the first and rate limiting step in bile acid synthesis.
The Rev-Erb proteins are members of the nuclear receptor (NR) superfamily of intracellular transcription factors and key regulatory components of the circadian clock. There are two forms of the receptor, Rev-Erb alpha and Rev-Erb beta, which are each encoded by a separate gene .
The liver receptor homolog-1 (LRH-1) also known as totipotency pioneer factor NR5A2 is a protein that in humans is encoded by the NR5A2 gene. LRH-1 is a member of the nuclear receptor family of intracellular transcription factors.
The small heterodimer partner (SHP) also known as NR0B2 is a protein that in humans is encoded by the NR0B2 gene. SHP is a member of the nuclear receptor family of intracellular transcription factors. SHP is unusual for a nuclear receptor in that it lacks a DNA binding domain. Therefore, it is technically neither a transcription factor nor nuclear receptor but nevertheless it is still classified as such due to relatively high sequence homology with other nuclear receptor family members.
Rev-Erb alpha (Rev-Erbɑ), also known as nuclear receptor subfamily 1 group D member 1 (NR1D1), is one of two Rev-Erb proteins in the nuclear receptor (NR) family of intracellular transcription factors. In humans, REV-ERBɑ is encoded by the NR1D1 gene, which is highly conserved across animal species.
Rev-Erb beta (Rev-Erbβ), also known as nuclear receptor subfamily 1 group D member 2 (NR1D2), is a member of the Rev-Erb protein family. Rev-Erbβ, like Rev-Erbα, belongs to the nuclear receptor superfamily of transcription factors and can modulate gene expression through binding to gene promoters. Together with Rev-Erbα, Rev-Erbβ functions as a major regulator of the circadian clock. These two proteins are partially redundant. Current research suggests that Rev-Erbβ is less important in maintaining the circadian clock than Rev-Erbα; knock-out studies of Rev-Erbα result in significant circadian disruption but the same has not been found with Rev-Erbβ. Rev-Erbβ compensation for Rev-Erbα varies across tissues, and further research is needed to elucidate the separate role of Rev-Erbβ.
Bert W. O'Malley is an endocrinologist from the United States. He was born in 1936 in the Garfield section of Pittsburgh, Pennsylvania. He received his early education at Catholic primary schools and Central Catholic High School, before pursuing higher education at the University of Pittsburgh, where he completed both his undergraduate and medical studies, graduating first in his class. It was here that he met Sally, who would become his wife and lifelong partner. The couple went on to have four children.
Retinoid X receptor alpha (RXR-alpha), also known as NR2B1 is a nuclear receptor that in humans is encoded by the RXRA gene.
Hepatocyte nuclear factor 4 alpha (HNF4A) also known as NR2A1 is a nuclear receptor that in humans is encoded by the HNF4A gene.
Retinoic acid receptor alpha (RAR-α), also known as NR1B1, is a nuclear receptor that in humans is encoded by the RARA gene.
Liver X receptor alpha (LXR-alpha) is a nuclear receptor protein that in humans is encoded by the NR1H3 gene.
Thyroid hormone receptor alpha (TR-alpha) also known as nuclear receptor subfamily 1, group A, member 1 (NR1A1), is a nuclear receptor protein that in humans is encoded by the THRA gene.
Liver X receptor beta (LXR-β) is a member of the nuclear receptor family of transcription factors. LXR-β is encoded by the NR1H2 gene.
