A new study identifies a feed-forward loop involving PpnGATA8, PpnGRF5, and PagXTH9 that helps convert polyploid gene dosage into enlarged leaf cells. This regulatory module explains how polyploid gene dosage may be translated into larger leaf cells, stronger photosynthesis, and more vigorous vegetative growth in poplar.
A study on Aspergillus oryzae found that increased cell volume and nuclear number contribute to its high enzyme production capacity. The fungus's hyphae thicken, resulting in a tenfold increase in cell volume, while the number of nuclei per hyphal cell also rises tenfold.
A research team from Nara Institute of Science and Technology developed a dynamic microfluidic channel that adjusts to particle size, increasing impedance flow cytometry's sensitivity and accuracy. The platform also leverages clogging as a strategy to optimize performance.
Researchers from Osaka University used machine learning to assess the shapes, sizes, and other physical features of bacteria based on microscope images. The results showed that antibiotic-resistant strains were fatter or shorter than their parental strains, especially those resistant to quinolone and β-lactams.
A team of researchers from the University of Arkansas has made a breakthrough in understanding species abundance by linking it to genome size. The study found that temperature and genome size are key drivers of diatom population growth rates, with body size still playing a role in colder latitudes.
Cancer cells' uncontrolled growth leads to a loss of ability to divide due to genetic damage accumulation. Simultaneous treatment with growth and division inhibitors can restore cellular function.
Researchers created a comprehensive index of human cells mapping sizes and abundance across the entire body. The study reveals surprising mathematical patterns underlying cell size and number, challenging fundamental understanding of cell growth and proliferation.
Quitting smoking early after a lung cancer diagnosis was associated with lower mortality rates. Detailed smoking history collection can improve lung cancer prognosis and treatment selection. The study's findings suggest that smoking cessation timing may impact overall survival, particularly at different clinical stages.
The study of nematodes' body size can inform scientists' understanding of cellular growth, with the goal of discovering novel genes that control cell size and potential targets for cancer treatment. Nematodes are a model species for biological studies due to their quick growth rate and ability to produce hundreds of eggs.
Scientists have discovered that cancer cells can manipulate their size to resist treatment, with smaller cells potentially more vulnerable to DNA-damaging agents and larger cells responding better to immunotherapy. This study provides new insight into how cell size affects disease and may lead to new treatment strategies.
Research reveals that smaller artificial cells lead to greater separation of molecules, allowing for a new approach to manipulate material properties. This discovery has potential applications in pharmaceuticals and cosmetics industries.
Researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function — replenishing the body’s blood cells — as they grow larger. However, when the cells were restored to their usual size, they behaved normally again.
Researchers found that cells regulate their own size by using DNA content as an internal scale. Cells with too little KRP4 delay DNA replication until they catch up, while those with too much dilute KRP4 to speed up the process. This mechanism keeps meristem cells within a narrow size range.
A recent study from Dartmouth College has uncovered the mechanism behind how cells determine their size, a crucial process that regulates cell division in growing organisms. The research found that histone H3 plays a key role in this process, releasing an enzyme called Chk1 to bind with another protein and stop cell multiplication.
A Penn study found that cell size controls the timing of genome activation in zygotes, shifting control from maternal molecules to individual cells. This discovery has significant implications for understanding early embryo development and may impact research approaches.
A multidisciplinary team at UC San Diego unraveled the mechanisms controlling cell size through a fundamental process known as 'the adder.' The process relies on balanced synthesis of biological ingredients and a critical threshold to initiate cell division. This discovery sheds light on the origins of precise cellular reproduction.
A recent study by Doyle and Coate explores the mechanisms of polyploidy in plants, highlighting its impact on cell biology and evolutionary novelty. The authors found that genome doubling can alter cell size, nuclear volume, and cell cycle duration, with many effects attributed to changes in bulk DNA amount.
A team of researchers found that endoreduplication, a process promoting cellular enlargement, occurs randomly and contributes to cell size variation. The study's mathematical model successfully reproduced experimental dynamics, revealing exponential boosting as the mechanism behind cell size determination.
A variation in the Cell Size Regulator gene enabled the domestication of large, plump tomatoes thousands of years ago. Farmers selectively cultivated plants with this genetic trait, which boosts fruit weight and increases profit margins.
Researchers at the University of East Anglia have discovered a gene that regulates the size of diatom cells, which contribute 20% to global primary production. The discovery could have significant implications for understanding the effects of climate change on future food webs and the potential impact on phytoplankton cell sizes.
A new study published in Current Biology found that bacterial cells are limited by their ability to produce fat, which affects their growth and size. The research, conducted at Washington University in St. Louis, used a novel approach to understand the role of biosynthesis in cell-size regulation.
A team of physicists, biologists, and bioengineers from UC San Diego developed a new
Researchers have mapped how plant cells determine size and adjust growth to achieve homogeneous cell sizes over time. This breakthrough overturns previous theories in the field, providing insights into factors determining plant size and fruit production.
Research at the John Innes Centre reveals that plant stem cells actively regulate their size to develop organs properly. The study shows that maintaining uniform cell sizes is crucial for organ formation, similar to pixel sizes in digital images.
Researchers at Princeton University may have found a key to understanding how cells assemble and grow to the right size. The nucleolus, a part of the cell responsible for making ribosomes, is shown to play a crucial role in regulating cell growth through phase transitions.
A novel study has provided an answer to the long-standing question of how cells control their size and maintain stable distributions. Researchers found that cells follow a simple quantitative principle, adding constant size irrespective of birth size, to ensure stability of size distributions.
A trio of enzymes regulates cell size in bacteria by sensing nutrient availability, with disruptions leading to defects in chromosome segregation. This discovery sheds light on the mechanisms behind uncontrolled growth in cancer cells.
Scientists at the Salk Institute discovered a link between cell size and growth in algae, which may provide new clues to cancer. They found that cells need specific proteins to divide on schedule once they reach a critical size.
Researchers found that sensory deprivation reduces the size of new interneurons in the olfactory system but compensates with increased excitability. This preserves the function of interneurons in processing input if restored.
