Model organisms have been used in the study of ARHGEF4 function. A conditional knockout mouse line, called Arhgef4tm1a(KOMP)Wtsi was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty two tests were carried out on homozygous mutant mice and one significant abnormality was observed: males has atypical peripheral blood lymphocyte parameters, including a decreased B cell number and an increased granulocyte number.

Famous quotes containing the words model and/or organisms:

    “When you model yourself on people, you should try to resemble their good sides.”
    —Molière [Jean Baptiste Poquelin] (1622–1673)

    “The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
    —Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
