ASF1B and uterine carcinosarcoma: To assess the degree of variability in ASF1B expression attributable to CNVs we additionally conducted correlation analyses revealing a positive association between ASF1B expression and CNVs in BRCA, CESC, HNSC, LUSC, OV, SARC, UCEC, and Uterine Carcinosarcoma (UCS), whereas this correlation was negative in ACC, LAML, and THYM (P<0.05) (Figure 3B).
