Effect of the polyphenol flavonoids fisetin and quercetin on the adipogenic differentiation of human mesenchymal stromal cells.

Fisetin and quercetin, polyphenol flavonoids, have been shown to have a wide range of beneficial pharmacological effects including anti-inflammatory, antioxidative, and anti-cancer. Our previous work shows that fisetin also affects the specification of the adipogenic-osteogenic lineage of human mesenchymal stem cells (hMSCs) by modulating the Hippo-YAP signaling pathway. Although quercetin has a structure similar to that of fisetin, its effects on the functional properties of hMSCs have not yet been investigated.

Clinical features and long-term outcomes of pediatric patients with de novo acute myeloid leukemia in China with or without specific gene abnormalities: a cohort study of patients treated with BCH-AML 2005.

Acute myeloid leukemia (AML), which has distinct genetic abnormalities, has unique clinical and biological features. In this study, the incidence, clinical characteristics, induction treatment response, and outcomes of a large cohort of Chinese AML pediatric patients treated according to the BCH-AML 2005 protocol were analyzed. was the most common fusion transcript, followed by the and rearrangements.

Exploring the prognostic value of T follicular helper cell levels in chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) presents with heterogeneous clinical outcomes, suggesting varied underlying pathogenic mechanisms. This study aims to elucidate the impact of T follicular helper (Tfh) cells on CLL progression and prognosis. Gene expression profile data for CLL were collected from GSE22762 and GSE39671 datasets.

Predictive and Prognostic Role of Systemic Immune-Inflammation Index (SII) in Metastatic Colorectal Cancer Patients Treated with Trifluridine/Tipiracil.

In advanced-stage colorectal cancer (CRC), a strategy based on a sequence of systemic therapies brings survival benefits in most patients. Trifluridine and tipiracil hydrochloride (TT) is a chemotherapy drug effective in patients in the third- or later line setting. No highly specific biomarkers have been established for TT therapy so far.

Correlating COVID-19 severity with biomarker profiles and patient prognosis.

COVID-19's long-lasting and complex impacts have become a global concern, with diverse clinical outcomes. This study evaluated 226 participants to understand the clinical spectrum of COVID-19/Long COVID (LC), exploring how disease severity correlates with sociodemographic factors and biomarkers. Determinants related to COVID-19 severity included age (P < 0.

Vitamin D reduces the expression of M1 and M2 macrophage markers in breast cancer patients.

Vitamin D (VD) is known for its immunomodulatory and anticancer effects. This study aimed to characterize tumor-associated macrophages (TAMs) in breast cancer (BC) and assess the influence of VD and its active metabolite, calcitriol, on their polarization. TAMs were isolated from BC patients and characterized.

Cluster of Differentiation Markers and Human Leukocyte Antigen Expression in Chronic Lymphocytic Leukemia Patients: Correlations and Clinical Relevance.

Chronic lymphocytic leukemia (CLL) is a distinct category of lymphoproliferative disorder characterized by the clonal expansion of mature B cells, followed by their accumulation in primary and secondary lymphoid organs. Cluster of differentiation (CD) markers such as CD79b, CD45, CD23, CD22 and CD81 serve as reliable prognostic indicators in CLL as well as the human leukocyte antigen (HLA) with its well-documented associations with various cancers. This study aims to investigate, for the first time, potential connections between HLA typing and CD marker expression in CLL.

Palbociclib in Solid Tumor Patients With Genomic Alterations in the cyclinD-cdk4/6-INK4a-Rb Pathway: Results From National Cancer Institute-Children's Oncology Group Pediatric Molecular Analysis for Therapy Choice Trial Arm I (APEC1621I).

Purpose: The National Cancer Institute-Children's Oncology Group Pediatric Molecular Analysis for Therapy Choice trial assigned patients age 1-21 years with relapsed or refractory solid tumors, lymphomas, and histiocytic disorders to phase II treatment arms of molecularly targeted therapies on the basis of genetic alterations detected in their tumor. Patients with tumors that harbored prespecified genomic alterations in the cyclinD-CDK4/6-INK4a-Rb pathway with intact Rb expression were assigned and treated with the cdk4/6 inhibitor palbociclib.

Methods: Patients received palbociclib orally once daily for 21 days of 28-day cycles until disease progression, intolerable toxicity, or up to 2 years.

Half body irradiation (HBI) for bone metastases in the modern radiotherapy technique era - A systematic review.

Bone metastases (BMs) are the most common cause of cancer-related pain and radiation therapy plays a key role in treating pain caused by it. The half-body irradiation (HBI) is a modality that can be used to treat patients with multiple painful BMs. In the modern era, concerns about toxicity and the availability of new agents requiring robust bone marrow function have limited the use of HBI in advanced cancer.

Telomere Length, HLA, and Longevity-Results from a Multicenter Study.

Aging is an exceptionally complex process that depends on genetic, environmental, and lifestyle factors. Previous studies within the International HLA and Immunogenetics Workshop (IHIWS) component "Immunogenetics of Ageing" showed that longevity is associated with positive selection of HLA-DRB1*11- and DRB1*16-associated haplotypes, shown to be protective against diseases. Within the 18th IHIWS, we aimed to investigate the relevance of telomere length for successful aging and its association with classical HLAs.

The clinical impact of serum soluble CD25 levels in children with Langerhans cell histiocytosis.

Objective: Langerhans cell histiocytosis (LCH) is a rare myeloid neoplasm with inflammatory characteristics. This study aims to investigate the correlation between sCD25 levels and clinical characteristics, as well as prognosis, in pediatric LCH.

Methods: Serum sCD25 levels were measured in 370 LCH patients under 18 years old using ELISA assays.

Aging is associated with functional and molecular changes in distinct hematopoietic stem cell subsets.

Age is a risk factor for hematologic malignancies. Attributes of the aging hematopoietic system include increased myelopoiesis, impaired adaptive immunity, and a functional decline of the hematopoietic stem cells (HSCs) that maintain hematopoiesis. Changes in the composition of diverse HSC subsets have been suggested to be responsible for age-related alterations, however, the underlying regulatory mechanisms are incompletely understood in the context of HSC heterogeneity.

YAP1 regulates thrombopoiesis by binding to MYH9 in immune thrombocytopenia.

Immune thrombocytopenia (ITP) is a complicated bleeding disease characterized by a sharp platelet reduction. As a dominating element involved in ITP, megakaryocytes (MKs) are responsible for thrombopoiesis. However, the mechanism underlying the dysregulation of thrombopoiesis that occurs in ITP remains unidentified.
