Article Synopsis
  • Thymic neuroendocrine tumors (Th-NETs) are rare, aggressive cancers, and this study aimed to evaluate how prognostic markers and TMZ-based chemotherapy affect patient survival.
  • The research involved reviewing records of 32 patients diagnosed with Th-NETs from 2013 to 2023, highlighting median progression-free survival of 12.5 months for those on TMZ and 51.0 months for surgical patients.
  • Key findings showed that the neutrophil-to-lymphocyte ratio (NLR) is a vital prognostic indicator, while high Ki67 levels and lack of surgery correlate with worse survival outcomes; suggesting that surgical treatment remains the primary therapy, with further focus needed on specific biomarkers.

Article Synopsis
  • ERK3/MAPK6 activates MK5, influencing cardiac fibroblast function and hypertrophy in male mice.
  • Male MK5 haplo-deficient mice show reduced cardiac hypertrophy and decreased Col1a1 mRNA when faced with increased cardiac afterload.
  • The study reveals that reduced ERK3 leads to lower heart mass and impacts fibroblast behavior, highlighting ERK3's crucial role in cardiac fibroblast biology.

Angiopoietin-like 2 (ANGPTL2) is a pro-inflammatory and pro-oxidant circulating protein that predicts and promotes chronic inflammatory diseases such as atherosclerosis in humans. Transgenic murine models demonstrated the deleterious role of ANGPTL2 in vascular diseases, while deletion of ANGPTL2 was protective. The nature of its role in cardiac tissues is, however, less clear.

Background: Type 1 gastric neuroendocrine tumors (NETs) are relatively rare to the extent that some physicians have little experience in diagnosing and treating them. The purpose of this study was to increase the understanding of the disease by analyzing and summarizing the management and prognoses of patients with type 1 gastric NETs at our center.

Methods: The data of 229 patients (59.

Introduction: Treatment response to the standard therapy is low for metastatic pancreatic neuroendocrine tumors (PanNETs) mainly due to the tumor heterogeneity. We investigated the heterogeneity between primary PanNETs and metastases to improve the precise treatment.

Methods: The genomic and transcriptomic data of PanNETs were retrieved from the Genomics, Evidence, Neoplasia, Information, Exchange (GENIE), and Gene Expression Omnibus (GEO) database, respectively.

Background: Polymorphisms in the adenylate cyclase 9 (ADCY9) gene influence the benefits of the cholesteryl ester transfer protein (CETP) modulator dalcetrapib on cardiovascular events after acute coronary syndrome. We hypothesized that Adcy9 inactivation could improve cardiac function and remodelling following myocardial infarction (MI) in absence of CETP activity.

Methods: Wild-type (WT) and Adcy9-inactivated (Adcy9) male mice, transgenic or not for human CETP (tgCETP), were subjected to MI by permanent left anterior descending coronary artery ligation and studied for 4 weeks.

The genetic characteristics of rectal neuroendocrine tumors (R-NETs) were poorly understood. Depicting the genetic characteristics may provide a biological basis for prognosis prediction and novel treatment development. Tissues of 18 R-NET patients were analyzed using whole-exome sequencing.

Aortic valve (AoV) abnormalities during embryogenesis are a major risk for the development of aortic valve stenosis (AVS) and cardiac events later in life. Here, we identify an unexpected role for Angiopoietin-like 2 (ANGPTL2), a pro-inflammatory protein secreted by senescent cells, in valvulogenesis. At late embryonic stage, mice knocked-down for Angptl2 (Angptl2-KD) exhibit a premature thickening of AoV leaflets associated with a dysregulation of the fine balance between cell apoptosis, senescence and proliferation during AoV remodeling and a decrease in the crucial Notch signalling.

Increased production of reactive oxygen species plays an essential role in the pathogenesis of several diseases, including cardiac hypertrophy. In our search to identify redox-sensitive targets that contribute to redox signaling, we found that protein tyrosine phosphatase 1B (PTP1B) was reversibly oxidized and inactivated in hearts undergoing hypertrophy. Cardiomyocyte-specific deletion of PTP1B in mice (PTP1B cKO mice) caused a hypertrophic phenotype that was exacerbated by pressure overload.

Hepatocellular carcinoma (HCC) is an immunogenic malignancy, which exhibits low responsiveness to programmed cell death protein‑1 (PD‑1)/programmed death ligand‑1 (PD‑L1) antibodies. Therefore, the identification of novel immunotherapeutic targets to treat HCC is imperative. Systematic characterization of the HCC tumor microenvironment (TME) can provide novel insight into additional therapeutic approaches.

Article Synopsis
  • The study analyzes clinical data from 153 patients with well-differentiated pancreatic neuroendocrine tumors (pNETG1 and pNETG2) to establish a better classification based on Ki-67 index.
  • The optimal cut-off value for separating pNETG1 and pNETG2 was found to be 5.5%, with significant differences in overall and disease-free survival at a Ki-67 index of 5%.
  • The research concludes that using a Ki-67 index threshold of 5% improves predictions for pNET mortality and recurrence compared to the previously used 3%.

Background: Neuroendocrine carcinoma of the breast (NECB) is a rare type of malignant tumor. Due to the rarity of NECB, the relevant literature mostly comprises case reports. Available data on treatment options for NECB are very limited.

Background: Glomus tumors are uncommon and mostly benign mesenchymal neoplasms of the perivascular family. To date, only a few cases of glomus tumors occurring in the trachea have been reported. Tracheal glomus tumors simulated low-grade neuroendocrine tumors on clinical and histomorphological examination, so the differential diagnosis between these two entities is very necessary.

Background: Pulmonary hypertension (PH) complicating idiopathic pulmonary fibrosis (IPF) is associated to worse outcome. There is a great need for a non-invasive diagnostic modality to detect and evaluate the severity of pulmonary vascular disease (PVD). Tc-PulmoBind is a novel imaging agent that binds to the adrenomedullin (AM) receptor on the pulmonary microvascular endothelium.

Evidence has demonstrated that miRNAs play an irreplaceable role in tumorigenesis and progression of a broad range of cancers, including gastric cancer. Among these miRNAs, miR-10a and miR-10b have been identified to critically participate in gastric carcinogenesis and malignant progression. In this review, we briefly describe the role of miR-10a and miR-10b in gastric cancer, especially in the regulation of cell proliferation, apoptosis, cell cycle, migration, invasion and metastasis, drug resistance, and cancer stem cells.

Article Synopsis
  • MK2-null mice show normal survival rates and initial cardiac function, but exhibit early signs of diastolic dysfunction and altered heart rate dynamics.
  • MK2 deficiency results in increased expression of key metabolic genes and affects mitochondrial sensitivity in the heart.
  • The findings suggest that MK2 plays a crucial role in autonomic heart regulation, mitochondrial function, and early cardiac remodeling during pressure overload.

Background: We previously demonstrated that high-density lipoprotein (HDL) infusions may improve left ventricular diastolic dysfunction (LVDD) in an aortic valve stenosis (AVS) model. Whether the benefit was direct or mediated by the observed reduction in AVS severity is not clear. Here, we aimed to test the direct effect of an ApoA-I mimetic on LVDD in the absence of AVS.
