The Pim-1 kinase regulates cell survival, proliferation, and differentiation and is overexpressed frequently in many malignancies, including leukemia and skin cancer. In this study, we used kinase profiling analysis to demonstrate that 2'-hydroxycinnamicaldehyde (2'-HCA), a compound found in cinnamon, specifically inhibits Pim-1 activity. Cocrystallography studies determined the hydrogen bonding pattern between 2'-HCA and Pim-1. Notably, 2'-HCA binding altered the apo kinase structure in a manner that shielded the ligand from solvent, thereby acting as a gatekeeper loop. Biologically, 2'-HCA inhibited the growth of human erythroleukemia or squamous epidermoid carcinoma cells by inducing apoptosis. The compound was also effective as a chemopreventive agent against EGF-mediated neoplastic transformation. Finally, 2'-HCA potently suppressed the growth of mouse xenografts representing human leukemia or skin cancer. Overall, our results offered preclinical proof of concept for 2'-HCA as a potent anticancer principle arising from direct targeting of the Pim-1 kinase.

Article Synopsis
  • Sarcoid-like reaction (SLR) is an immune response affecting lymph nodes and organs, which doesn't fulfill the criteria for systemic sarcoidosis, and can be associated with certain diseases like Chronic lymphocytic leukaemia (CLL) and Amyotrophic lateral sclerosis (ALS).
  • A 60-year-old male patient with treated CLL developed ALS symptoms following exposure to Venetoclax and Rituximab, presenting with rashes and weakness that progressed over a year.
  • Diagnosis complications included atypical signs and symptoms, leading to misdiagnosis of neurosarcoidosis and challenges in treatment, despite initial interventions with prednisolone and infliximab.

Ponatinib, a tyrosine kinase inhibitor used for chronic myeloid leukemia and acute lymphoblastic leukemia, can cause rare cutaneous side effects. In this case, a 63-year-old woman developed a pityriasis rubra pilaris-like eruption 1 month after starting the drug. The skin reaction improved with dose reduction and recurred more mildly at a lower dose.

Background: Talquetamab (anti-G protein-coupled receptor family C group 5 member D) and teclistamab (anti-B-cell maturation antigen) are bispecific antibodies that activate T cells by targeting CD3 and that have been approved for the treatment of triple-class-exposed relapsed or refractory multiple myeloma.

Methods: We conducted a phase 1b-2 study of talquetamab plus teclistamab in patients with relapsed or refractory multiple myeloma. In phase 1, we investigated five dose levels in a dose-escalation study.

JAGN1 (Jagunal-homolog1) is a ER-resident transmembrane protein which is part of the early secretory pathway and granulocyte colony-stimulating factor receptor mediated signaling. Autosomal recessively inherited variants in the JAGN1 gene lead to congenital neutropenia, early-onset bacterial infections, aphthosis and skin abscesses due to aberrant differentiation and maturation of neutrophils. In addition, bone metabolism disorders and a syndromic phenotype, including facial features, short stature and neurodevelopmental delay, have been reported in affected patients.

Evaluation of QuantiFERON-TB Gold for the Diagnosis of Infection in HTLV-1-Infected Patients.

Human T-cell leukemia virus type 1 (HTLV-1) is associated with an increased risk of tuberculosis (TB). This study aimed to evaluate the performance of the QuantiFERON-TB Gold (QFT) test for the diagnosis of (MTB) infection in HTLV-1-infected individuals. HTLV-1-infected participants were divided into four groups: HTLV-1-infected individuals with a history of tuberculosis (HTLV/TB), individuals with positive HTLV and tuberculin skin tests (HTLV/TST+) or negative TST (HTLV/TST-), and HTLV-1-negative individuals with positive TST results (HN/TST+).
