Rice has long been a staple food for more than half the global population. The United Nations even declared 2004 the International Year of Rice to raise awareness and encourage action to protect and advance the crop for a rapidly growing population. The genetic guidance rice uses to grow and reproduce, however, is still not fully understood. Now, a research team based in Japan is learning more, including how critical one gene is for the plant to develop grains of rice, which serve as both seeds and food.

By searching for the protein transglutaminase 1 (TGM1) among patients with various autoimmune skin diseases, researchers have successfully identified a separate disease that can be linked to autoimmunity against TGM1. This backward method demonstrates a new way of identifying autoantigens as markers for various diseases. By letting autoantigens point to the disease, diagnosis and treatment can be facilitated, according to the study now published in PNAS.

We have succeeded in establishing a mouse model that develops gastric cancer closely resembling advanced human gastric cancer. Using this model, we have discovered gastric cancer stem cells, i.e. Lgr5+ gastric cancer cells, essential for the development, maintenance, and metastasis of cancer. Our study provides an experimental system that enables detailed analysis of highly malignant gastric cancer and is expected to lead to the development of a breakthrough treatment for advanced human gastric cancer.

Giants in History: Chinese agronomist Yuan Longping (7 September 1930 – 22 May 2021) developed the first varieties of the high-yield, hybrid rice that brought food security to multiple countries including China, which had been ravaged by food shortages as recently as the mid-20th century.

Researchers have identified a potential reason why lower numbers of COVID cases have appeared amongst smokers compared to non-smokers, even as other reports suggest smoking increases severity of the disease.

A research team led by Hiroshima University Professor Satoshi Okada has determined that enhanced bone resorption activity due to a faulty immune response may underpin multifocal osteomyelitis — painful, chronic bone infections — in children with MSMD, a rare genetic condition resulting from a range of immune system mutations.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease. Byproducts of errant processes can build up like gunk in the gears, especially around neurons, breaking down the repair mechanisms and causing further damage and even neurodegenerative disorders such as Alzheimer’s disease.

Researchers discover a link between an increase in protein Ba of the complement immune system and the eventual development of thrombotic microangiopathy in patients who have received an allogeneic hematopoietic stem cell transplantation.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

Many genetic variants have been found to have a linkage with genetic diseases, but the understanding of their functional roles in causing diseases are still limited. An international research team, including a biomedical scientist from City University of Hong Kong (CityU), has developed a high-throughput biological assay technique which enabled them to conduct a systematic analysis on the impact of nearly 100,000 genetic variants on the binding of transcription factors to DNA. Their findings provided valuable data for finding key biomarkers of type 2 diabetes for diagnostics and treatments. And they believe that the new technique can be applied to studies of variants associated with other genetic diseases.

Cells replicate their genetic material and divide into two identical clones to perpetuate life. Some cells pause in the process with a single, undivided nucleus. When the cell resumes division after such a pause, the nucleus can become caught in the fissure, splitting violently, and killing both cells. But that is not always the case. Researchers from Hiroshima University in Japan are starting to understand how active nuclear displacement rescues cell death.
