The Absence of HIF-1α Increases Susceptibility to Leishmania donovani Infection via Activation of BNIP3/mTOR/SREBP-1c Axis

2020

Summary: Hypoxia-inducible factor-1 alpha (HIF-1α) is considered a global regulator of cellular metabolism and innate immune cell functions. Intracellular pathogens such as Leishmania have been reported to manipulate host cell metabolism. Herein, we demonstrate that myeloid cells from myeloid-restricted HIF-1α-deficient mice and individuals with loss-of-function HIF1A gene polymorphisms are more susceptible to L. donovani infection through increased lipogenesis. Absence of HIF-1α leads to a defect in BNIP3 expression, resulting in the activation of mTOR and nuclear translocation of SREBP-1c. We observed the induction of lipogenic gene transcripts, such as FASN, and lipid accumulation in inf…

High-Risk Patients with Differentiated Thyroid Cancer T4 Primary Tumors Achieve Remnant Ablation Equally Well Using rhTSH or Thyroid Hormone Withdraw…

2013

Few data exist on using thyrotropin alfa (recombinant human thyroid-stimulating hormone [rhTSH]) with radioiodine for thyroid remnant ablation of patients who have T4 primary tumors (invasion beyond the thyroid capsule).A retrospective chart review protocol at nine centers in Europe was set up with special waiver of need for informed consent, along with a careful procedure to avoid selection bias when enrolling patients into the database. Data on 144 eligible patients with T4 tumors were collected (T4, N0-1, M0-1; mean age 49.7 years; 65% female; 88% papillary cancer). All had received (131)I remnant ablation following TSH stimulation with rhTSH or thyroid hormone withdrawal (THW) since Jan…
