Innate immunity is activated when the pattern recognition receptors (PRRs) recognize pathogen-associated molecular patterns (PAMPs). We show that a liver-derived secretory protein LECT2, a hepatokine, binds to the HGF receptor MET, a proto-oncogene product, to suppress the proliferation signal of MET. LECT2 activates retinoic acid-inducible gene-I, enhancing antiviral and innate immune responses through MET. Thus, LECT2 is an anti-proliferative and immunoregulatory factor that could be a therapeutic target for viral infections and cancer.

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.

We have clarified at the molecular level the mechanism by which a microenvironment, a so-called niche that surrounds cancer cells, is formed in which stromal cells and immune cells are attracted at an initiation stage of breast cancer onset. A molecule called FRS2β is found to be critical for creating this microenvironment. The present finding is expected to be beneficial in prevention, diagnosis and treatment of cancers at the initiation stage.

Malfunctioning of the so-called Hippo signalling pathway within animal cells leads to irregular activity of proteins that regulate genes involved in cell proliferation. Researchers have identified a key step in the process of this aberration, opening the door to new therapeutics for cancers such as head-and-neck squamous cell carcinoma and lung adenocarcinoma.

Researchers reveal correlation between ribotype (RT) strains of Cutibacterium acnes, which are found in human skin, and the lifespan of the nematode Caenorhabditis elegans. Strains RT4 and 8, which are associated with acne in human skin, shortened the lifespan of the nematode, while RT6, which are predominantly found in healthy human skin, did not. Also, it was found that the healthy skin-related RT6 strain of C. acnes improved C. elegans resistance to the pathogenic organism Staphylococcus aureus.

Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.

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.
