Researchers from Osaka University have identified a protein, FER1L5, that is essential for sperm to acquire fertilizing ability. Sperm from mice lacking this protein were unable to undergo the “acrosome reaction”, which releases molecules that facilitate fertilization, resulting in impaired male fertility. As FER1L5 is also present in human sperm, this work may lead to new diagnostic methods and treatments for male infertility in humans.

Aspergillus aculeatus
10 Jan 2023
An Osaka Metropolitan University research team analyzed the regulatory mechanisms of carbohydrate-hydrolyzing enzyme production in Aspergillus aculeatus, a filamentous fungus that produces enzymes with an excellent ability to degrade plant biomass. The team found that UDP-glucose 4-epimerase (Uge5), an enzyme known for its involvement in galactose metabolism, also regulates the expression of degrading enzyme genes in A. aculeatus. This is the very first report of Uge5’s roles in selective gene expression in response to different types of inducing sugars in filamentous fungi.

Researchers from Osaka University have developed a culture system using pluripotent cells from southern and northern white rhinos, which was refined to produce primordial germ cell-like cells (PGCLCs). These cells are the equivalent of primordial germ cells, the origin of eggs and sperm. The study marks an important first step in the potential production of northern white rhino gametes, which could be used in breeding programs, and is the first to induce PGCLCs in a wild animal.

Research led by Hong Kong Baptist University (HKBU) involving the use of a pioneering female sterility technique has led to a breakthrough in the production of hybrid rice seeds. Compared to the commonly used “three-line” male sterility technique in hybrid rice seeds production, the novel approach enhances the efficiency of hybrid rice production by eliminating rice seeds that have been produced due to the self-pollination of the “restorer line”. The novel technique enables fully automatic harvesting of hybrid seeds by machines, which can substantially reduce harvesting costs.

Osaka Metropolitan University researchers introduced seven proteins, thought to let bacteria swim by switching the direction that their helical bodies spiral, into a strain of synthetic bacterium with minimal genetic information. As a result, they confirmed that the synthetic bacterium named syn3, which is normally spherical, formed a helix that could swim by spiraling. Further investigation revealed that only two of these newly added proteins were required to make syn3 capable of minimal swimming. This swimming synthetic bacterium can be said to be the smallest mobile lifeform genetically, as it contains the fewest number of genes.

Scientists understand genes related to intellectual disabilities, but are often unsure of how mutations in these genes cause developmental disorders. Now, a research group led by two Tohoku University researchers has uncovered the role of CHAMP1—a gene whose mutations are associated with intellectual disability—in neuronal development.

Rice flower and ovule
04 Feb 2022
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.

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.

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.
