Association between contralateral adrenal and hypothalamus-pituitary-adrenal axis in benign adrenocortical tumors.

Context: Adrenal incidentaloma (AI) is commonly discovered on cross-sectional imaging. Mild autonomous cortisol secretion is the most common functional disorder detected in AI.

Objective: To delineate the association between radiological characteristics of benign adrenocortical tumors and hypothalamus-pituitary-adrenal (HPA) axis.

SDHB immunohistochemistry for prognosis of pheochromocytoma and paraganglioma: A retrospective and prospective analysis.

Introduction: Pheochromocytomas and paragangliomas (PCC/PGL) are rare neuroendocrine tumors and can secrete catecholamine. Previous studies have found that SDHB immunohistochemistry (IHC) can predict SDHB germline gene mutation, and SDHB mutation is closely associated with tumor progression and metastasis. This study aimed to clarify the potential effect of SDHB IHC as a predictive marker for tumor progression in PCC/PGL patients.

Immunohistochemical Analysis of CYP11B2, CYP11B1 and β-catenin Helps Subtyping and Relates With Clinical Characteristics of Unilateral Primary Aldosteronism.

Primary aldosteronism is caused by aldosterone overproduction. While conventional hematoxylin-eosin staining can demonstrate morphological abnormality, it cannot provide any functional histopathological information. We aimed to identify the diagnostic, functional and prognostic value of CYP11B2, CYP11B1, and β-catenin immunostaining in unilateral hyperaldosteronism.

KCNJ5 Mutation Contributes to Complete Clinical Success in Aldosterone-Producing Adenoma: A Study From a Single Center.

Objective: The KCNJ5 mutation is the most frequent mutation in aldosterone-producing adenoma (APA). We aimed to illustrate the relationship between KCNJ5 and prognosis after adrenalectomy as a guide for further treatment.

Methods: Our study included 458 patients with APA.

Senescent Stromal Cells Promote Cancer Resistance through SIRT1 Loss-Potentiated Overproduction of Small Extracellular Vesicles.

Cellular senescence is a potent tumor-suppressive program that prevents neoplastic events. Paradoxically, senescent cells develop an inflammatory secretome, termed the senescence-associated secretory phenotype, which is implicated in age-related pathologies including cancer. Here, we report that senescent cells actively synthesize and release small extracellular vesicles (sEV) with a distinctive size distribution.

Association between thyroid function and serum cortisol in cortisol-producing adenoma patients.

Purpose: Thyroid dysfunction has been reported in hypercortisolism. Previous findings regarding changes in thyroid function due to cortisol-producing adenoma (CPA) have been inconsistent. The study aimed to investigate the association between thyroid function and excessive cortisol secretion in patients with CPA and to explore the changes in pituitary function after adrenalectomy.

MicroRNA-125a-Loaded Polymeric Nanoparticles Alleviate Systemic Lupus Erythematosus by Restoring Effector/Regulatory T Cells Balance.

Systemic lupus erythematosus (SLE), a common lethal autoimmune disease, is characterized by effector/regulatory T cells imbalance. Current therapies are either inefficient or have severe side effects. MicroRNA-125a (miR-125a) can stabilize Treg-mediated self-tolerance by targeting effector programs, but it is significantly downregulated in peripheral T cells of patients with SLE.

Copy Number Variation Pattern for Discriminating MACROD2 States of Colorectal Cancer Subtypes.

Copy number variation (CNV) is a common structural variation pattern of DNA, and it features a higher mutation rate than single-nucleotide polymorphisms (SNPs) and affects a larger fragment of genomes. CNV is related with the genesis of complex diseases and can thus be used as a strategy to identify novel cancer-predisposing markers or mechanisms. In particular, the frequent deletions of mono-ADP-ribosylhydrolase 2 () locus in human colorectal cancer (CRC) alters DNA repair and the sensitivity to DNA damage and results in chromosomal instability.

Targeting amphiregulin (AREG) derived from senescent stromal cells diminishes cancer resistance and averts programmed cell death 1 ligand (PD-L1)-mediated immunosuppression.

Aging is characterized by a progressive loss of physiological integrity, while cancer represents one of the primary pathological factors that severely threaten human lifespan and healthspan. In clinical oncology, drug resistance limits the efficacy of most anticancer treatments, and identification of major mechanisms remains a key to solve this challenging issue. Here, we highlight the multifaceted senescence-associated secretory phenotype (SASP), which comprises numerous soluble factors including amphiregulin (AREG).

Revisiting Non-BRCA1/2 Familial Whole Exome Sequencing Datasets Implicates as a Cancer Gene.

Through linkage and candidate gene screening, many breast cancer (BC) predisposition genes have been identified in the past 20 years. However, the majority of genetic risks that contribute to familial BC remains undetermined. In this study, we revisited whole exome sequencing datasets from non-BRCA1/2 familial BC patients, to search for novel BC predisposition genes.

From clinic to mechanism: Proteomics-based assessment of angiogenesis in adrenal pheochromocytoma.

Adrenal pheochromocytoma (PCC) is a very rare tumor that stems from chromaffin cells, which can develop into malignant tumor. During the operation, abundant blood vessels were often observed in PCC than other adrenal tumors, which increases the difficulty and risk of the surgery. Therefore, it is important to investigate the mechanism of PCC angiogenesis.

PZR promotes metastasis of colorectal cancer through increasing FAK and Src phosphorylation.

Metastasis is the main cause of death in patients with colorectal cancer (CRC), but the molecular mechanism is not yet fully understood. Previous studies have shown that P zero-related protein (PZR), a member of the immunoglobulin family, can promote fibronectin-dependent migration of mouse embryonic fibroblasts as well as invasion and metastasis of hepatic carcinoma cells. However, the role of PZR in CRC remains unclear.

A novel clinical nomogram to predict bilateral hyperaldosteronism in Chinese patients with primary aldosteronism.

Context: Adrenal venous sampling (AVS) is recommended as the gold standard for subtype classification in primary aldosteronism (PA); however, this approach has limited availability.

Objective: We aimed to develop a novel clinical nomogram to predict PA subtype based on routine variables, thereby reducing the number of candidates for AVS.

Patients And Method: Patients were randomly divided into a training set (n = 185) and a validation set (n = 79).

Retrospective analysis of variant venous anatomy in 303 laparoscopic adrenalectomies and its clinical implications.

Background And Objectives: To clarify the correlation of variant venous anatomy with adrenal tumor phenotype and surgical outcomes.

Patients And Methods: This retrospective study included 303 consecutive minimally invasive adrenalectomies from 301 patients. All adrenal veins were identified.

Ferroptosis as a target for protection against cardiomyopathy.

Heart disease is the leading cause of death worldwide. A key pathogenic factor in the development of lethal heart failure is loss of terminally differentiated cardiomyocytes. However, mechanisms of cardiomyocyte death remain unclear.

Reduced production of laminin by hepatic stellate cells contributes to impairment in oval cell response to liver injury in aged mice.

Aged liver is usually impaired in response to hepatic injury. Tissue-specific stem cells participate in the repair of tissue injury. However, how oval cells (OCs) respond to injury and how the process is regulated by tissue microenvironment in aged mice have not been fully understood.

Feminizing Adrenocortical Carcinoma: The Source of Estrogen Production and the Role of Adrenal-Gonadal Dedifferentiation.

Background: Feminizing adrenocortical carcinoma (ACC) is rare. The source of estrogen production and the underlying mechanism remain unclear.

Objective: In the current study, we investigated the source and the molecular mechanism of estrogen production in feminizing ACC.

Poly IC pretreatment suppresses B cell-mediated lupus-like autoimmunity through induction of Peli1.

Noncanonical NF-κB pathway is essential for the B cell activation and antibody production, which centralize the critical role of B cells in regulating the pathogenesis of systemic lupus erythematosus (SLE). We have previously demonstrated that Pellino1 (Peli1) negatively regulates noncanonical NF-κB activation and lupus autoimmunity. Here, we showed that poly IC is a potent inducer of Peli1 protein in mouse splenic B cells in dose- and time-dependent manners, and poly IC-induced Peli1 protein dramatically suppressed the activation of noncanonical NF-κB pathway.

Comprehensive assessment of T-cell repertoire following autologous hematopoietic stem cell transplantation for treatment of type 1 diabetes using high-throughput sequencing.

Objective: We aimed to investigate T-cell receptor (TCR) repertoires in type 1 diabetes (T1D) patients receiving autologous hematopoietic stem cell transplantation (AHSCT) treatment.

Methods: High-throughput deep TCR beta (TCRB) chain sequencing was performed to assess millions of individual TCRs in five T1D patients receiving AHSCT treatment and another five patients receiving insulin treatment during 12 months of follow-up.

Results: No significant changes in TCRB sequence reads, complementarity-determining region 3 (CDR3) sequences, or the usage of TCRB VJ gene-segments were observed at 12 months after AHSCT.

Decrease of Perivascular Adipose Tissue Browning Is Associated With Vascular Dysfunction in Spontaneous Hypertensive Rats During Aging.

Functional perivascular adipose tissue (PVAT) is necessary to maintain vascular physiology through both mechanical support and endocrine or paracrine ways. PVAT shows a brown adipose tissue (BAT)-like feature and the browning level of PVAT is dependent on the anatomic location and species. However, it is not clear whether PVAT browning is involved in the vascular tone regulation in spontaneously hypertensive rats (SHRs).

The senescence-associated secretory phenotype is potentiated by feedforward regulatory mechanisms involving Zscan4 and TAK1.

The senescence-associated secretory phenotype (SASP) can be provoked by side effects of therapeutic agents, fueling advanced complications including cancer resistance. However, the intracellular signal network supporting initiation and development of the SASP driven by treatment-induced damage remains unclear. Here we report that the transcription factor Zscan4 is elevated for expression by an ATM-TRAF6-TAK1 axis during the acute DNA damage response and enables a long term SASP in human stromal cells.

Clinical benefits of autologous haematopoietic stem cell transplantation in type 1 diabetes patients.

Unlabelled: Type 1 diabetes (T1D) is characterized by severe damage to pancreas islet function through immunological attack; therefore, it is also called 'insulin-dependent diabetes'. The present study aimed to evaluate the safety and clinical efficacy of autologous haematopoietic stem cell transplantation (AHSCT) in adolescent patients with newly diagnosed T1D. A phase-II prospective, parallel-assignment, non-randomized trial was conducted from March 2008 to December 2011 with 40 T1D patients, of whom 20 received AHSCT therapy and 20 were treated only with insulin injections.

F-fluorodeoxyglucose uptake predicts MET expression in lung adenocarcinoma.

Objective: MET is a member of the receptor tyrosine kinases. Several MET-targeting inhibitors and antagonistic antibodies have shown promising data in clinical trials of lung adenocarcinoma. Finding noninvasive diagnostic tools to estimate the status of MET is helpful in clinical practice.
