PROX1 is a regulator of neuroendocrine-related gene expression in lung carcinoid.

Lung neuroendocrine neoplasms (NENs) are a diverse group of tumors characterized by neuroendocrine (NE) differentiation. Among lung NENs, lung carcinoid (LC) is a rare tumor with unique characteristics. Recent research has highlighted the importance of transcription factors (TFs) in establishing gene expression programs in lung NENs such as small cell lung carcinoma.

Humoral and Cellular Response Induced by Primary Series and Booster Doses of mRNA Coronavirus Disease 2019 Vaccine in Patients with Cardiovascular Disease: A Longitudinal Study.

Preexisting cardiovascular disease (CVD) is a pivotal risk factor for severe coronavirus disease 2019 (COVID-19). We investigated the longitudinal (over 1 year and 9 months) humoral and cellular responses to primary series and booster doses of mRNA COVID-19 vaccines in patients with CVD. Twenty-six patients with CVD who received monovalent mRNA COVID-19 vaccines were enrolled in this study.

Multifaced roles of the long non-coding RNA DRAIC in cancer progression.

Long non-coding RNAs (lncRNA) are functional RNAs, with over 200 nucleotides in length and lacking protein-coding potential. Studies have indicated that lncRNAs are important gene regulators under physiological conditions. Aberrant lncRNA expression is associated with the initiation and progression of various diseases, including cancers.

Chromogenic hybridization reveals specific expression pattern of long non-coding RNA in formalin-fixed paraffin-embedded specimen.

Long non-coding RNA (lncRNA) plays an important role in the regulation of gene expression in normal and cancer cells. We previously discovered a novel tumor-suppressive lncRNA, , in prostate cancer cells. Subsequent studies have demonstrated that is dysregulated in various malignancies and exhibits a tumor-suppressive or pro-oncogenic function.

Resting echocardiographic parameters can exclude significant coronary artery disease: A comparison with coronary computed tomography angiography.

Introduction: Coronary computed tomography angiography (CCTA) is known to have a high negative predictive value (NPV) in identifying coronary artery disease (CAD). This study aimed to examine whether resting echocardiographic parameters could exclude significant CAD on CCTA.

Methods: We recruited 142 patients who had undergone both CCTA and echocardiography within a 3-month window.

Comparison of the Serial Humoral Immune Response according to the Immunosuppressive Treatment after SARS-CoV-2 mRNA Vaccination.

Objective The objective of this study was to estimate the humoral immune response evaluated by immunoglobulin G (IgG) against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike receptor-binding domain (RBD-IgG) following the third mRNA coronavirus disease 2019 (COVID-19) vaccination in patients with kidney disease who received immunosuppressive treatment. Methods The primary outcome was RBD-IgG levels after the third SARS-CoV-2 vaccination. The primary comparison was the RBD-IgG levels between patients with kidney disease who received immunosuppressive treatment (n=124) and those who did not (n=33).

Transcriptome of Oral Cancer Cells Adapted to Suspension Culture Is Potentially Related to Cancer Progressive Phenotypes.

Background/aim: Cervical lymph node metastasis worsens oral cancer prognosis. Cancer cells with high metastatic ability can delay or resist apoptosis and survive in the floating condition during circulation. The involved genes and pathways in this process remain largely unknown.

in Serum Extracellular Vesicles Reflects Resistance to AR Axis-targeted Therapy Among CRPC Patients.

Background/aim: We aimed to evaluate the changes of androgen receptor (AR) signaling-related long non-coding RNAs (lncRNAs) in serum extracellular vesicles (EVs) from prostate cancer (PC) patients, in order to identify novel biomarkers for AR axis-targeted therapy (ARAT)-resistance among castration-resistant PC (CRPC) patients.

Patients And Methods: EVs were isolated from 2 patients before and after acquiring ARAT-resistance. RNA profiling of EVs was performed by RNA-sequencing.

Dataset dependency of low-density lipoprotein-cholesterol estimation by machine learning.

Objectives: We evaluated the applicability of a machine learning-based low-density lipoprotein-cholesterol (LDL-C) estimation method and the influence of the characteristics of the training datasets.

Methods: Three training datasets were chosen from training datasets: health check-up participants at the Resource Center for Health Science ( = 2664), clinical patients at Gifu University Hospital ( = 7409), and clinical patients at Fujita Health University Hospital ( = 14,842). Nine different machine learning models were constructed through hyperparameter tuning and 10-fold cross-validation.

Spermidine enhances the efficacy of adjuvant in HBV vaccination in mice.

Unlabelled: Background: Various vaccine adjuvants have been developed to eliminate HBV from patients with chronic HBV infection. In addition, spermidine (SPD), a type of polyamine, has been reported to enhance the activity of immune cells. In the present study, we investigated whether the combination of SPD and vaccine adjuvant enhances the HBV antigen-specific immune response to HBV vaccination.

Serum angiotensin-converting enzyme levels indicating early sarcoidosis diagnosis and immunosuppressive therapy efficacy.

Aims: This study aimed to determine the new cut-off value of serum angiotensin-converting enzyme (ACE) levels for detecting patients with sarcoidosis and to examine the change in ACE levels after the initiation of immunosuppressive therapy.

Methods And Results: We retrospectively examined patients in whom serum ACE levels were measured for suspected sarcoidosis between 2009 and 2020 in our institution. For patients diagnosed with sarcoidosis, changes in ACE levels were also observed.

Administration of spermidine attenuates concanavalin A-induced liver injury.

A previous study revealed that treatment with the anticoagulant heparin attenuated concanavalin A (ConA)-induced liver injury. The administration of spermidine (SPD) increased urokinase-type plasminogen activator (uPA) levels in the serum. uPA is clinically used for the treatment of some thrombotic diseases such as cerebral infarction.

Cytomorphology and Gene Expression Signatures of Anchorage-independent Aggregations of Oral Cancer Cells.

Background/aim: Cancer cells with high anchorage independence can survive and proliferate in the absence of adhesion to the extracellular matrix. Under anchorage-independent conditions, cancer cells adhere to each other and form aggregates to overcome various stresses. In this study, we investigated the cytomorphology and gene expression signatures of oral cancer cell aggregates.

Absence of indoleamine 2,3‑dioxygenase 2 promotes liver regeneration after partial hepatectomy in mice.

The partial loss of liver due to liver transplantation or acute liver failure induces rapid liver regeneration. Recently, we reported that the selective inhibition of indoleamine 2,3‑dioxygenase (Ido) 1 promotes early liver regeneration. However, the role of Ido2 in liver regeneration remains unclear.

Treatment with hepatocyte transplantation in a novel mouse model of persistent liver failure.

Background And Aim: Cell-based transplantation therapy using hepatocytes, hepatic stem cells, hepatocyte-like cells induced from stem cells, etc. is thought to be an attractive alternative to liver transplantation, and have been studied to date. For its clinical application, however, it is extremely important to develop a model that reproduces the pathological conditions with indication for treatment and enables the study for the ideal treatment strategy.

d-mannose administration improves autoimmune hepatitis by upregulating regulatory T cells.

A recent study revealed that d-mannose suppressed immunopathology in mouse models of autoimmune diabetes and airway inflammation and increased the proportion of regulatory T cells (Tregs) in mice. We investigated the effect of d-mannose on liver injury in murine autoimmune hepatitis (AIH) models induced by concanavalin A (ConA) and α-galactosylceramide (GalCer). Mouse models of AIH were created by intraperitoneal injection of GalCer or intravenous injection of ConA.

Histology of Cardiac Sarcoidosis with Novel Considerations Arranged upon a Pathologic Basis.

Sarcoidosis is a rare disease of isolated or diffuse granulomatous inflammation. Although any organs can be affected by sarcoidosis, cardiac sarcoidosis is a fatal disorder, and it is crucial to accurately diagnose it to prevent sudden death due to dysrhythmia. Although endomyocardial biopsy is invasive and has limited sensitivity for identifying granulomas, it is the only modality that yields a definitive diagnosis of cardiac sarcoidosis.
