Baltimore, MD—Carnegie’s Steven Farber was awarded nearly $500,000 over three years by The G. Harold & Leila Y. Mathers Foundation to identify the chemical components of cinnamon oil that show effectiveness against cardiovascular disease-causing fats.

Fat molecules, or lipids, such as cholesterol and triglycerides are shuttled around the circulatory system by a protein called Apolipoprotein-B, together forming complexes of lipid and protein that are called lipoproteins but may be more commonly known as “bad cholesterol.” It can get embedded in the sides of blood vessels and harden, forming a dangerous buildup that makes it more difficult for the heart

Baltimore, MD—Carnegie William Ludington’s quest to understand the community ecology of our gut microbiome was this spring awarded nearly $1 million over three years from the National Science Foundation. He was also selected as one of 14 researchers to receive $55,000 from the Research Corporation for Science Advancement for its inaugural Scialog: Microbiome, Neurobiology, and Disease initiative.

“Since he arrived at Carnegie in 2018, Will has been aggressively pursuing breakthroughs in microbiome research—deploying a multitude of genetic, physiological, and mathematical approaches,” said Carnegie Embryology Director Yixian Zheng. “These two

Baltimore, MD— The CRISPR/Cas9 genome editing system can help scientists understand, and possibly improve, how corals respond to the environmental stresses of climate change. Work led by Phillip Cleves—who joined Carnegie’s Department of Embryology this fall—details how the revolutionary, Nobel Prize-winning technology can be deployed to guide conservation efforts for fragile reef ecosystems.

Cleves’ research team’s findings were recently published in two papers in the Proceedings of the National Academy of Sciences.

Corals are marine invertebrates that build extensive calcium carbonate skeletons from which reefs are constructed. But this

Baltimore, MD—Human activity endangers coral health around the world. A new algal threat is taking advantage of coral’s already precarious situation in the Caribbean and making it even harder for reef ecosystems to grow.

Just-published research in Scientific Reports details how an aggressive, golden-brown, crust-like alga is rapidly overgrowing shallow reefs, taking the place of coral that was damaged by extreme storms and exacerbating the damage caused by ocean acidification, disease, pollution, and bleaching.

Approximately half of the gene sequences of human and mouse genomes comes from so-called mobile elements—genes that jump around the genome. Much of this DNA is no longer capable of moving, but is likely “auditioning”  perhaps as a regulator of gene function or in homologous recombination, which is a type of genetic recombination where the basic structural units of DNA,  nucleotide sequences, are exchanged between two DNA molecules to  repair  breaks in the DNA  strands. Modern mammalian genomes also contain numerous intact movable elements, such as retrotransposon LINE-1, that use RNA intermediates to spread about the genome.

The Gall laboratory studies all aspects of the cell nucleus, particularly the structure of chromosomes, the transcription and processing of RNA, and the role of bodies inside the cell nucleus, especially the Cajal body (CB) and the histone locus body (HLB).

Much of the work makes use of the giant oocyte of amphibians and the equally giant nucleus or germinal vesicle (GV) found in it. He is particularly  interested in how the structure of the nucleus is related to the synthesis and processing of RNA—specifically, what changes occur in the chromosomes and other nuclear components when RNA is synthesized, processed, and transported to the cytoplasm.

In mammals, most lipids, such as fatty acids and cholesterol, are absorbed into the body via the small intestine. The complexity of the cells and fluids that inhabit this organ make it very difficult to study in a laboratory setting. The goal of the Farber lab is to better understand the cell and molecular biology of lipids within digestive organs by exploiting the many unique attributes of the clear zebrafish larva  to visualize lipid uptake and processing in real time.  Given their utmost necessity for proper cellular function, it is not surprising that defects in lipid metabolism underlie a number of human diseases, including obesity, diabetes, and atherosclerosis.

The Fan laboratory studies the molecular mechanisms that govern mammalian development, using the mouse as a model. They use a combination of biochemical, molecular and genetic approaches to identify and characterize signaling molecules and pathways that control the development and maintenance of the musculoskeletal and hypothalamic systems.

The musculoskeletal system provides the mechanical support for our posture and movement. How it arises during embryogenesis pertains to the basic problem of embryonic induction. How the components of this system are repaired after injury and maintained throughout life is of biological and clinical significance. They study how this system is

The Ludington lab investigates complex ecological dynamics from microbial community interactions using the fruit fly  Drosophila melanogaster. The fruit fly gut carries numerous microbial species, which can be cultured in the lab. The goal is to understand the gut ecology and how it relates to host health, among other questions, by taking advantage of the fast time-scale and ease of studying the fruit fly in controlled experiments. 

The mouse is a traditional model organism for understanding physiological processes in humans. Chen-Ming Fan uses the mouse to study the underlying mechanisms involved in human development and genetic diseases. He concentrates on identifying and understanding the signals that direct the musculoskeletal system to develop in the mammalian embryo. Skin, muscle, cartilage, and bone are all derived from a group of progenitor structures called somites. Various growth factors—molecules that stimulate the growth of cells—in the surrounding tissues work in concert to signal each somitic cell to differentiate into a specific tissue type.

The lab has identified various growth

The first step in gene expression is the formation of an RNA copy of its DNA. This step, called transcription, takes place in the cell nucleus. Transcription requires an enzyme called RNA polymerase to catalyze the synthesis of the RNA from the DNA template. This, in addition to other processing factors, is needed before messenger RNA (mRNA) can be exported to the cytoplasm, the area surrounding the nucleus.

Although the biochemical details of transcription and RNA processing are known, relatively little is understood about their cellular organization. Joseph G. Gall has been an intellectual leader and has made seminal breakthroughs in our understanding of chromosomes, nuclei and
