Does the Organization of DNA During Sperm Development have an Effect on Future Offspring?

Share on:

Researchers at Technion’s Rappaport Faculty of Medicine present new findings regarding the organization of DNA during sperm formation and its implications on future organisms. The research which was published in the journal Nature Structural & Molecular Biology was done by Prof. Noam Kaplan and MSc student Haia Khoury from the Technion, together with their colleagues at Cincinnati Children’s Hospital Medical Center. Leading the research at Cincinnati were Prof. Satoshi Namekawa and research student Kris Alvattam.

  The DNA in the living cell is packed, together with the proteins attached to it, in a molecular complex called chromatin. Although it may seem that the chromatin serves only as a packaging of genetic data within the DNA, the way in which the DNA is packed considerably influences cellular systems. For example, DNA that is tightly packed may become inaccessible to biological machinery which reads the DNA, possibly leading to inactivation of genes encoded in that DNA sequence.  

This current research examined the organization of the DNA during spermatogenesis – sperm development. Although spermatogenesis has been long studied, the way in which DNA is packed during this process has not been mapped in detail due to technological challenges. Now, researchers have met this challenge by using a novel technology, called Hi-C, which combines experimental molecular biology with computational analysis to measure the spatial organization of DNA.    

Each day, millions of sperm cells are created in the human male body. One of the critical stages in the formation of sperm cells is meiosis (cell division). Early in meiosis, DNA is drastically reorganized as the chromosomes condense in preparation of the upcoming cell division. Furthermore, these condense chromosomes swap segments of DNA and in this way increase genetic variation.

The Israeli-American research team successfully isolated mouse sperm cells at the start of meiosis when the chromosomes are condensed and then used Hi-C to measure the spatial organization of the DNA. The researchers discovered that the spatial structure of the chromatin gradually strengthens during spermatogenesis, until it reaches its ultimate strength in the mature sperm. They suggest that this organization enables the sperm cells to activate a wide variety of genes during meiosis, enabling the cells to later gain the unique ability of producing all cell types after fertilization. According to Dr. Kaplan, “In the future, we intend to use this approach in order to understand how the genome’s spatial structure may influence fertility.”      

This research was funded by the National Institutes of Health (NIH), Azrieli Foundation and the Henry and Marilyn Taub Scholarship.

Prof. Kaplan joined the Technion Rappaport Faculty of Medicine in 2016 and established an interdisciplinary laboratory for studying the spatial structure and function of genomes in health and disease.

Haia Khoury completed her BSc at the Technion’s Faculty of Biology and is currently pursuing an MSc in Biomedical Sciences at the Technion Rappaport Faculty of Medicine.

CT for Clouds: A Fleet of Micro-Satellites Will See into the Smallest Clouds

Share on:

An Israeli-German mission to launch a formation of ten tiny satellites that use medically-inspired CT (computed tomography) algorithms to answer climate questions wins a (US) $15.9 million European Research Council award.

Ten satellites, each around the size of a shoebox, are slated to enter orbit in a few years and begin filling in some gaping holes in our understanding of clouds and their role in climate. Inspired by medical CT (computed tomography), which observes and maps the interior of a patient, the designers are creating a system that will reveal detailed images of clouds’ external and internal 3D structures and properties. By probing small cloud fields that are generally missed by today’s remote sensing technologies, the mission may resolve some major uncertainties that limit current atmospheric modeling and climate prediction.

(L-R) Prof. Ilan Koren, Prof. Yoav Schechner, and Prof. Klaus Schilling

This space mission, called CloudCT, was recently awarded €14 million by the European Research Council (ERC) Synergy program — the maximum sum that can be allotted from this program. Three investigators lead this unique interdisciplinary project: two Israelis and a German. Prof. Yoav Schechner of the Viterbi Faculty of Electrical Engineering at the Technion (Haifa) is an expert in computer vision and computed tomography. Prof. Ilan Koren is an expert in cloud and rain physics in the Earth and Planetary Sciences Department of the Weizmann Institute of Science (Rehovot). Prof. Klaus Schilling of the Center for Telematics (Würzburg) is a leader in the field of small satellite formation technology.

Clouds have a key role in Earth’s energy balance and its water cycle; even small errors in assessing clouds’ properties can lead to major inaccuracies in climate predictions. “Satellites study large cloud structures, but lack the resolution to observe small clouds,” says Koren. “Although they are small, such clouds temper the climate, on the one hand, and on the other, they may be very sensitive to climate change. That is why there is a critical need to measure these small clouds properly — to understand their nature and their interplay with changing environmental conditions. CloudCT can pave the way to this understanding.”

The idea for probing these clouds from space was motivated by the technology of 3D medical imaging. “We are using human health as guidance for the planet’s health,” Schechner says. In analogy to the better-known medical CT, images in CloudCT will be taken simultaneously from many directions around and above the clouds. This feat will be made possible by the networked self-organizing formation of multiple, affordable, very small and very agile satellites. However, “Contrary to isolated clinic laboratory settings, Earth is irradiated by illumination from the Sun, which cannot be moved around or turned on and off. Our image-analysis algorithms must account for this reality and rely on light scattering, which challenges our task.”

The precision control required of the multi-satellite system (each satellite weighing around three kilograms) so as to conduct this complex imaging raises challenges in miniaturization, as well as in coordination and autonomous reaction capabilities. Schilling professes excitement about the prospects of the CloudCT project: “The distributed networked satellite systems we are developing for CloudCT are an example of the ways that innovative software compensates for the deficits brought about by miniaturization. This enables a self-organizing system to be implemented efficiently by such ultra-small satellites and for novel approaches to observation to help achieve scientific advances.”

The scientists are now building their teams and starting to work out details of the project. They will spend time designing and testing many aspects of CloudCT prior to launch. “This testing is assisted by a precursor mission of three satellites, called TOM – Telematics Earth Observation Mission, as well as our high-performance dynamics simulator in Würzburg,” says Schilling. “This project will give us the opportunity to see and measure clouds as never before,” adds Koren.  “We are very pleased that the ERC selected the CloudCT project,” says Schechner. “We can already say that CloudCT is pioneering new concepts of Earth observation and the development of sophisticated computational imaging algorithms.”
