Based on the results seen in Dow Coming's DoE testing, a new Gen 3 fluorosilicone compound was formulated to provide long-term property retention when exposed to today's most widely used ATFs: Mercon LV, ATF+4, Dexron VI and Pentosin ATF1.

Yeast that lack the ATF1
gene, which encodes an enzyme that produces the fruity aroma chemicals, grow just fine in the lab, says geneticist Kevin Verstrepen of the University of Leuven and VIB, a research institute also in Belgium.
40) Occasional cases with EWSR1 rearrangement have failed to show involvement of ATF1
or CREB1, suggesting that these may have as yet unidentified fusion partners.
Since this assay does not provide information regarding the translocation partner, additional FISH studies were performed, which showed rearrangement of the ATF1
locus on 12q13 (Figure 3, B).
However in contrast to MM, CCSTA is characterized by the t(12;22)(q13;q12) that leads to the fusion of the ATF1
gene localized to 12q13 to the EWSR1 gene at 22q12 in up to 90% of cases.
