77 Blood Test for Cancer #SpaceTravel

77−1 Proteo Inspection

○ By this examination, it is possible to risk judgment of cancers including pancreatic cancer from early stage by blood test. [1]

・With biochip using novel substance Silver Peroxide Meso Crystals: Proteo®, it is possible to determine the presence or absence of cancer, the type of cancer, and the degree of progress from stage 0 with a single drop of blood.

・Peroxide Meso Crystals, biochip Proteo® directly and quickly detects a tiny amount of cancer-related substances Nucleosomes existing in the blood, and makes it possible to distinguish the cancer in stage 0 and judge its progress.

※Nucleosomes:A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores.

・It was developed in collaboration with Showa University Hospital and Mytech Corporation.

※ Subject: Solid cancer such as pancreatic cancer, lung cancer, breast cancer, stomach cancer, liver cancer, colon cancer, tongue cancer, thyroid cancer, kidney cancer, prostate cancer, uterine cancer, ovarian cancer

・20170301 Japan Society of Clinical Study for Frontier-Medicine(JSCSF)started clinical research..[2]

※List of laboratories


※ Inspection cost: about 500$

77−2 MicroRNA Inspection [4]

• Cancer cells secrete specific microRNAs.

• Evaluated 13 types of cancer in 4 grades.

• Cost: About 200$

• Task: Even if it is not breast cancer, 20% is judged as cancer. It should be less than 5%.

• National Cancer Research Center (Tokyo) started clinical research in August 2017

• Project schedule: 2020 ~
