Here, we investigated the potential interaction between bromodomain-containing protein 4 (BRD4), an established epigenetic modulator and transcriptional coactivator, and p63, a member of the p53 transcription factor family, essential for epithelial development and skin homeostasis. Our protein-protein interaction assays demonstrated a strong and conserved physical interaction between BRD4 and the p53 family members-p63, p73, and p53-suggesting a shared binding region among these proteins. While the role of BRD4 in cancer development through its interaction with p53 has been explored, the effects of BRD4 and Bromodomain and Extra Terminal (BET) inhibitors in non-transformed cells, such as keratinocytes, remain largely unknown.
View Article and Find Full Text PDFAims: Traditional cardiovascular (CV) biomarkers (high-sensitivity troponinT [hsTnT] and N-terminal pro-B-type natriuretic peptide [NT-proBNP]) are important to monitor cancer patients' cardiac function and to assess prognosis. Newer CV biomarkers (mid-regional pro-adrenomedullin [MR-proADM], C-terminal pro-arginine vasopressin [copeptin], and mid-regional pro-atrial natriuretic peptide [MR-proANP]) might outperform traditional biomarkers.
Methods And Results: Overall, 442 hospitalized cancer patients without significant CV disease or current infection were enrolled (61 ± 15 years, 52% male, advanced cancer stage: 85%) and concentrations of CV biomarkers were analysed.
Article Synopsis
- The study investigates the role of p63, a transcription factor, in skin aging and keratinocyte senescence, revealing that the depletion of p63 accelerates aging markers in both animal models and human cells.
- Using advanced metabolomic analysis techniques, the research identifies key metabolic pathways linked to cell senescence that change when p63 is silenced, affecting stress markers and lipid production.
- Findings suggest that p63 plays a crucial role in managing metabolic processes in keratinocytes, potentially offering insights into therapeutic strategies against skin aging and related conditions.
Background: Iron deficiency and iron deficiency anemia represent global health issues, particularly during pregnancy and the postpartum. The present paper aims to summarize the appropriate management of these conditions in order to try to improve how clinicians perceive, diagnose and treat iron deficiency and iron deficiency anemia.
Methods: An expert panel of Italian obstetricians of Lazio region was convened to evaluate the available literature on iron deficiency and iron deficiency anemia during pregnancy and the post-partum in order to try to define a flow chart on the appropriate management of such conditions; aspects related to the patient blood management have also been investigated.
Background: Growth hormone (GH) resistance is characterized by high GH levels but low levels of insulin-like growth factor-I (IGF-I) and growth hormone binding protein (GHBP) and, for patients with chronic disease, is associated with the development of cachexia.
Objectives: We investigated whether GH resistance is associated with changes in left ventricular (LV) mass (cardiac wasting) in patients with cancer.
Methods: We measured plasma IGF-I, GH, and GHBP in 159 women and 148 men with cancer (83% stage III/IV).
