The fluorescent blinking of cyanine dye (Alexa Fluor 647, pink star) bound to RNA changes depending on the structure of the RNA. When the RNA is folded like a hairpin, the fluorescent blinking is fast, and when the RNA switches to a G-quadruplex, the blinking is slow (Akira Kitamura).

Cancer cell infiltrates the liver through intracellular gaps in LSECs
04 Oct 2022
Metastasis—when cancer spreads to form new tumors—causes approximately 90% of cancer-related deaths. Because metastatic cancer cells circulate in the blood, the liver—which filters the blood—is considered the most vulnerable organ, so treatments that prevent liver metastasis are urgently needed. A team of Osaka Metropolitan University researchers discovered a mechanism that allows metastatic cancer cells to infiltrate the liver, and how that infiltration can be blocked by inhibiting a related protein.

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.

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.

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.
