Method for searching and screening for target of anti-cancer agent using non-human animal model having NOG established cancer cell line transplanted therein

An objective of the present invention is to provide non-human animal models of cancer pathology, which mimic the hierarchical organization, cancer progression process, or biological property of human cancer tissues, and uses thereof. To achieve the objective described above, first, the present inventors transplanted cells of NOG-established cancer lines into NOG mice and morphologically observed the resulting tissue organization. As a result, the non-human animal models were demonstrated to exhibit pathologies (the hierarchical organization, cancer progression process, or biological properties of the cancer cells) similar to that of human cancer. Specifically, the present inventors succeeded in preparing non-human animal models exhibiting pathologies more similar to a human cancer, and cell culture systems using NOG-established cancer cell lines where the in vitro cell morphology is more similar to that of human cancer.

Method for producing animal model of preterm birth and animal model of preterm birth produced by the method

The present invention relates to a method for producing an animal model of preterm birth and an animal model of preterm birth produced by the method. The animal model of the present invention can be effectively applied to investigate the causes and symptoms of preterm birth induced by cervical injury. The mortality rate of the animal model according to the present invention is low until preterm birth despite its induced preterm birth. In addition, the animal model of the present invention is produced in a higher yield than any other existing model. Furthermore, the preterm birth of the animal model according to the present invention is induced at a desired time point. Due to these advantages, the animal model of the present invention can be effectively applied to investigate the causes and mechanisms of preterm birth. The mortality rate of premature neonates born from the animal model of the present invention is considerably low and the premature neonates are immature. Therefore, the animal model of the present invention can be effectively applied to studies on complications of premature neonates.

20220396613 · 2022-12-15 ·

This invention relates to the finding that testis development related protein (TDRP; also termed Immunomoodulin or Imood herein) is a circulatory anxiogenic factor that modulates anxiety-like behaviour in mammalian models through the regulation of the immune system. Methods of treatment of mental disorders, such as anxiety, and TDRP antagonists for use in such methods are provided. Methods of diagnosing or monitoring a mental disorder in an individual by determining levels of TDRP in a sample and methods of screening for compounds that reduce levels of TDRP are provided.
