A new immune signature for survival prediction and immune checkpoint molecules in non-small cell lung cancer.

Background: Immune checkpoint blockade (ICB) therapy has brought remarkable clinical benefits to patients with advanced non-small cell lung carcinoma (NSCLC). However, the prognosis remains largely variable.

Methods: The profiles of immune-related genes for patients with NSCLC were extracted from TCGA database, ImmPort dataset, and IMGT/GENE-DB database.

Follicular cytotoxic CD8 T cells present high cytokine expression, and are more susceptible to Breg-mediated suppression in non-small cell lung cancer.

Tumor-infiltrating CD8 T cells are instrumental to antitumor immunity. In this study, we found that a subset of CXCR5-expressing CD8 T cells, termed follicular cytotoxic T (Tfc) cells, potently infiltrated the untreated tumors from non-small cell lung cancer (NSCLC) patients. On average, Tfc cells represented 14% of total tumor-infiltrating CD8 T cells and 6.

Uterus globulin associated protein 1 (UGRP1) is a potential marker of progression of Graves' disease into hypothyroidism.

Approximately 20% of Graves' disease (GD) patients may result eventually in hypothyroidism in their natural course. Uterus globulin-associated protein 1 (UGRP1) was associated with GD in our previous study. Here we investigated the role of UGRP1 in the development of autoimmune thyroid disease (AITD).

SRC1 Deficiency in Hypothalamic Arcuate Nucleus Increases Appetite and Body Weight.

Appetite is tightly controlled by neural and hormonal signals in animals. In general, steroid receptor co-activator 1 (SRC1) enhances steroid hormone signalling in energy balance and serves as a common co-activator of several steroid receptors, such as estrogen and glucocorticoid receptors. However, the key roles of SRC1 in energy balance remain largely unknown.

Upregulation of bacterial-specific Th1 and Th17 responses that are enriched in CXCR5CD4 T cells in non-small cell lung cancer.

The microbial community in the mucosal surfaces is involved in the development of human cancers, including gastric cancer and colorectal cancer. The respiratory tract in the lung also hosts a distinctive microbial community, but the correlation between this community and lung cancer is largely unknown. Here, we examined the Th1 and Th17 responses toward several bacterial antigens, in CD4 T cells sourced from the peripheral blood (PB), the lung cancer (LC) tissue, and the gastrointestinal (GI) tract of non-small cell lung cancer (NSCLC) patients.

Function and regulation of LAG3 on CD4CD25 T cells in non-small cell lung cancer.

LAG3 is a surface molecule found on a subset of immune cells. The precise function of LAG3 appears to be context-dependent. In this study, we investigated the effect of LAG3 on CD4CD25 T cells from non-small cell lung cancer (NSCLC) patients.

Exposure to particulate matter 2.5 (PM2.5) induced macrophage-dependent inflammation, characterized by increased Th1/Th17 cytokine secretion and cytotoxicity.

Particulate matter PM2.5 is a class of airborne particles and droplets with sustained high levels in many developing countries. Epidemiological studies have shown the association between sustained high level of PM2.

Function of follicular helper T cell is impaired and correlates with survival time in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) represents one of the most common and aggressive cancers worldwide. The PD-1/PD-L1 interaction plays important roles in cancer immunology, and expression of PD-L1 has been discovered in NSCLC tumor cells. Since follicular helper T (Tfh) cells have characteristic high PD-1 expression, we therefore investigated the inflammatory status of Tfh in NSCLC.

Interleukin 17A genetic variations and susceptibility to non-small cell lung cancer.

Lung cancer is the leading cause of cancer-related death, in which non-small cell lung cancer (NSCLC) is the most common type. Evidence have shown that interleukin 17 (IL-17) greatly involves in human immune responses. In this study, we investigated the effect of IL-17 on NSCLC by examining the association between IL-17A genetic polymorphisms and the susceptibility to NSCLC.

Tumour length is an independent prognostic factor of esophageal squamous cell carcinomas.

Background: The latest version of the American Joint Committee on Cancer (AJCC) TNM staging system has not comprehensively evaluated the impact of tumour length on survival in patients with esophageal squamous cell carcinoma. Our study explored the relationship between tumour length and clinicopathological characteristics as well as long-term survival.

Methods: All 202 cases of esophageal resections done from January 1, 2004 to December 31, 2008 in Huashan Hospital, Fudan University were reviewed and followed up.

The significance of MAGED4 expression in non-small cell lung cancer as analyzed by real-time fluorescence quantitative PCR.

The aim of this study was to detect differences in the expression levels of melanoma-associated antigen D4 (MAGED4) mRNA between non-small cell lung cancer (NSCLC) tissues and normal tissues, and to compare differences in the expression levels of MAGED4 in tumor patients. Patients were grouped according to age, gender, smoking history, tumor size, pathological classification, degree of lung cancer cell differentiation and presence of lymph node metastasis. The expression levels of MAGED4 were detected using real-time fluorescence quantitative PCR.

Application of the titanium plate fixation system in sternum transverse incisions.

The purpose of this study was to review the application of the titanium plate fixation system in sternum transverse incisions and assess its advantages over the conventional methods of steel wire fixation. Sternal healing of 249 patients who underwent a thymectomy and/or excision of the thymoma with a transverse sternal incision was compared between patients who underwent titanium plate fixation or steel wire fixation. Short-term results: The stability of the sternum was significantly superior in the titanium plate group compared with the steel wire group (P < 0.

The mechanism of mimecan transcription induced by glucocorticoid in pituitary corticotroph cells.

Mimecan, a secretary protein that is expressed in mouse and human pituitary corticotroph cells, is up-regulated by glucocorticoids (GC) in the corticotroph cells via classical glucocorticoid receptor (GR) pathways. In this study, we further explore the GC mechanism for mimecan expression in these cells. Five putative GR response elements (GREs) were identified in ~2 kb of the mimecan promoter by programme analysis.

Mimecan in pituitary corticotroph cells may regulate ACTH secretion and the HPAA.

Mimecan is a protein of unknown function that is expressed in the pituitary tissues of mouse and human. In this study, we observed the function of mimecan on the proopiomelanocortin (POMC) gene in the pituitary and the hypothalamo-pituitary-adrenal axis (HPAA). Incubating pituitary corticotroph AtT-20 cells with recombinant mimecan protein stimulated adrenocorticotrophic hormone (ACTH) secretion without significantly up-regulating POMC gene expression.

Glucocorticoid up-regulates mimecan expression in corticotroph cells.

Mimecan is a protein of unknown function that is expressed in the pituitary. The aim of this study is to clarify the regulation and intracellular localisation of mimecan gene expression in the pituitary. With immunohistochemistry, we observed that mimecan protein was co-expressed with ACTH in pituitary corticotroph cells.

Expression of adiponectin receptors in mouse adrenal glands and the adrenocortical Y-1 cell line: adiponectin regulates steroidogenesis.

Obesity is frequently associated with malfunctions of the hypothalamus-pituitary-adrenal (HPA) axis and hyperaldosteronism, but the mechanism underlying this association remains unclear. Since the adrenal glands are embedded in adipose tissue, direct cross-talk between adipose tissue and the adrenal gland has been proposed. A previous study found that adiponectin receptor mRNA was expressed in human adrenal glands and aldosterone-producing adenoma (APA).

Different expression of mimecan as a marker for differential diagnosis between NSCLC and SCLC.

Mimecan mRNA was present in a limited number of mouse and human tissues, however, abundant mimecan mRNA was observed in the lung tissue. Therefore, we hypothesize that mimecan could serve as a biomarker for differentiating various histological types of lung cancers. In humans, the mimecan mRNA was found most abundant in ovary and less abundant in lung by using Northern blot analysis.

The mimecan gene expressed in human pituitary and regulated by pituitary transcription factor-1 as a marker for diagnosing pituitary tumors.

Context: Mimecan, a secretory protein, belongs to a family of small leucine-rich proteoglycans (SLRPs). The physiological functions of mimecan have not been fully understood.

Objective: We hypothesize that the mimecan gene expressed in the human pituitary and regulated by pituitary transcription factor-1 (Pit-1) might act as a marker for diagnosing pituitary tumors.
