Exogenous T3 treatment prevent HCB induced molecular alterations related to hepatocyte proliferation whereas T4 did not have any effect. These effects were prevented by using a TGF-β1 receptor II inhibitor. Results suggest that alteration of TH homeostasis, through D1 function, play a key role in hepatocyte proliferation and that TGF-β1-SMAD pathway is involved in this process confirming their role in early neoplastic transformation in HCC.Acute leukemias are the most common neoplasm in pediatric patients. Currently, 80% of children with diagnosis of acute lymphoblastic leukemia (ALL) are cured with conventional chemotherapy, but 20% of them will have a recurrence of the disease. Measurable Residual Disease (MRD) has been described as an important prognostic factor that allows evaluating the response of patients to treatment. One of the most sensitive techniques to study MRD is the quantification of immunoglobulins (Ig) and T-lymphocyte receptors (TCR) genes rearrangements. The aims of this study were to describe the detected Ig/TCR rearrangements, to evaluate the prognostic impact of MRD in our population of children with ALL and to compare the MRD values by Ig/TCR with those obtained by multiparametric flow cytometry (MFC). A total of 455 patients were studied. In 96% of the cases, it was possible to characterize at least one Ig/TCR rearrangement. The total number of Ig/TCR rearrangements detected was 1550. MRD was successfully applied in 89% of the cases. The combined positive MRD values at day 33 and 78 of treatment allow the identification of high-risk patients in cases previously stratified by MRD using flow cytometry at day 15. The comparison between MRD determination by Ig/TCR rearrangements and FC showed excellent correlation. The present work constitutes a study of MRD by Ig/TCR c
