Formosan rock macaque of feeding macaques (in parks, along roadsides), particularly on the west coast, which increases their interaction and incidents with humans. Recent efforts by the government have tried to stop this behaviour, with mixed results. Formosan rock macaque The Formosan rock macaque ("Macaca cyclopis"), Formosan rock monkey, or Taiwanese macaque, is a macaque endemic to the island of Taiwan and has been introduced to Japan. Besides humans, Formosan rock macaques are the only native primates living in Taiwan. Rock macaques measure 50–60 cm and weigh 5–12 kg, generally females are smaller. Their tails are moderately long and measure 26–45 cm. This
Rhesus macaque significance because the macaque is used as an experimental model of the human immune system. In humans, the preferentially expressed antigen of melanoma (PRAME) gene family is expanded. It is actively expressed in cancers, but normally is testis-specific, possibly involved in spermatogenesis. The PRAME family has 26 members on human chromosome 1. In the macaque, it has eight, and has been very simple and stable for millions of years. The PRAME family arose in translocations in the common mouse-primate ancestor 85 million years ago, and is expanded on mouse chromosome 4. DNA microarrays are used in macaque research. For example,
