Researchers analyzed data from 14 studies involving nearly 27,000 participants to find genetic factors influencing the levels of tissue plasminogen activator (tPA), a key enzyme in blood clot breakdown.
They identified three significant genetic loci associated with tPA levels: one linked to the STXBP5 gene on chromosome 6, another near the PLAT gene on chromosome 8, and a third related to the STX2 gene on chromosome 12.
Functional tests showed that silencing STXBP5 reduces tPA release from cells, while silencing STX2 increases it, suggesting these genes play important roles in regulating tPA levels.
