HOXB9 promotes laryngeal squamous cell carcinoma progression by upregulating MMP12.

Transcriptional factor HOXB9, a part of the HOX gene family, plays a crucial role in the development of diverse cancer types. This study aimed to elucidate the regulatory mechanism of HOXB9 on the proliferation and invasion of laryngeal squamous cell carcinoma (LSCC) cells to provide guidance for the development and prognosis of LSCC. The CRISPR/Cas9 method was employed in LSCC cell lines to knock out the HOXB9 gene and validate its effects on the proliferation, migration, invasion, and regulation of LSCC cells.

ALDH enzyme activity is regulated by Nodal and histamine in the A549 cell line.

The present study aimed to examine whether the enzyme activity of aldehyde dehydrogenase (ALDH) was regulated by Nodal and histamine in the human alveolar adenocarcinoma A549 cell line. The regulated enzyme activity of ALDH was analyzed by flow cytometry in the A549 cell line. ALDH1 and Nodal expression was investigated by immunohistochemistry in28 cases of lung mixed adenocarcinoma.

HOXB9 Expression Correlates with Histological Grade and Prognosis in LSCC.

The purpose of this study was to investigate the HOX gene expression profile in laryngeal squamous cell carcinoma (LSCC) and assess whether some genes are associated with the clinicopathological features and prognosis in LSCC patients. The HOX gene levels were tested by microarray and validated by qRT-PCR in paired cancerous and adjacent noncancerous LSCC tissue samples. The microarray testing data of 39 HOX genes revealed 15 HOX genes that were at least 2-fold upregulated and 2 that were downregulated.

Plasma Gelsolin Induced Glomerular Fibrosis via the TGF-β1/Smads Signal Transduction Pathway in IgA Nephropathy.

Glomerular fibrosis has been shown to be closely related to the progression and prognosis of IgA nephropathy (IgAN). However, mechanism underlying IgAN glomerular fibrosis remains unclear. Recently, our study showed that plasma gelsolin (pGSN) was decreased in the serum of an IgAN mouse model and that pGSN deposition was found in the glomeruli.

Plasma Gelsolin Promotes Proliferation of Mesangial Cell in IgA Nephropathy.

Background/aims: Plasma gelsolin (pGSN) is an actin-binding protein that plays a critical role in the pathogenesis of rheumatoid arthritis. However, whether pGSN is involved in other immunological diseases remains unknown. This study focused on the relationship between pGSN and immunoglobulin A (IgA) nephropathy (IgAN).

miR-136 suppresses tumor invasion and metastasis by targeting RASAL2 in triple-negative breast cancer.

MicroRNAs play an important role in the regulation of cancer migration, invasion and metastasis. Patients with triple-negative breast cancer (TNBC) have a high incidence of early relapse and metastasis; however, the molecular basis for metastasis and recurrence in these individuals remains largely unknown. Herein, we demonstrate that miR-136 is an anti-invasive microRNA in TNBC and suppresses mesenchymal invasion and metastasis.

5-Hydroxymethylcytosine expression is associated with poor survival in cervical squamous cell carcinoma.

Objective: Deoxyribonucleic acid methylation is an important epigenetic modification that is frequently altered in cancer. Recent reports showed that the level of 5-hydroxymethylcytosine was altered in various types of cancers. The influence of deoxyribonucleic acid methylation in cervical squamous cell carcinoma is not fully understood.

Co-Positivity for Anti-dsDNA, -Nucleosome and -Histone Antibodies in Lupus Nephritis Is Indicative of High Serum Levels and Severe Nephropathy.

Objective: To characterize the significance of correlated autoantibodies in systemic lupus erythematosus (SLE) and its complication lupus nephritis (LN) in a large cohort of patients.

Methods: Clinical data were statistically analyzed in 1699 SLE patients with or without nephritis who were diagnosed and treated during 2002-2013 in the northeast region of China. Reactivity to a list of 16 autoantibodies was detected by the serum test Euroline ANA profile (IgG).

Correlation analysis of angiotensin-converting enzyme, angiotensinogen, and endothelial nitric oxide synthase gene polymorphisms and the progression of immunoglobulin A nephropathy/membranous nephropathy.

The purpose of our study was to evaluate the correlation of polymorphisms in angiotensinogen (AGT), angiotensin-converting enzyme (ACE), and endothelial nitric oxide synthase (eNOS) genes and the development and prognostic implications for immunoglobulin A nephropathy (IgAN)/membranous nephropathy (MN). A polymerase chain reaction was performed for the AGT, ACE, and eNOS genes, followed by DNA sequencing and statistical analysis. There was a difference in ACE gene type II and type I between the IgAN and MN groups (P < .

Plasma gelsolin levels are decreased and correlate with fibrosis in IgA nephropathy.

IgA nephropathy (IgAN) is an immune complex glomerulonephritis that is characterized by recurrent hematuria as the main clinical manifestation. In this study, we used the IgAN mouse model which was previously established to investigate the possible mechanism by which IgAN fibrosis correlates with decreased plasma gelsolin (pGSN) levels. We investigated the levels of pGSN, transforming growth factor β1 (TGFβ1), and oxidative stress markers including superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and malondialdehyde (MDA) in the serum and renal tissues of different groups.

Application of Oxford classification, and overexpression of transforming growth factor-β1 and immunoglobulins in immunoglobulin A nephropathy: correlation with World Health Organization classification of immunoglobulin A nephropathy in a Chinese patient cohort.

Immunoglobulin A nephropathy (IgAN) is characterized by the qualitative abnormality of immunoglobulin A (IgA) in circulation and deposits of IgA in the renal mesangium. Transforming growth factor β1 (TGF-β1) plays a key role in fibrogenesis and the progression of renal damage. This study aimed to investigate the clinicopathologic data on IgAN in northeastern China and the presence of TGF-β1, total IgA, and secretory IgA in the glomeruli and sera, as well as changes in galactose-deficient IgA1 in the serum.

Serum levels of alpha-smooth muscle actin and c-Met as biomarkers of the degree of severity of Henoch-Schonlein purpura nephritis.

Approximately 40% of patients with Henoch-Schonlein purpura (HSP) develop Henoch-Schonlein purpura nephritis (HSPN) after 4 to 6 weeks of subcutaneous hemorrhaging. Immunoglobulin-A nephropathy (IgAN) and HSPN have numerous similarities, which can cause difficulty in correctly diagnosing the disorder during a differential diagnosis. The pathogenesis of the 2 diseases is not clear.

The relationship between HBV serum markers and the clinicopathological characteristics of hepatitis B virus-associated glomerulonephritis (HBV-GN) in the northeastern chinese population.

Background: To investigate the effect of HBV markers on HBV-GN.

Methods: The immunohistochemistry was used to detect HBsAg and HBcAg in frozen sections of renal biopsy, the changes in HBV serum markers, renal functional parameters and clinical manifestations or symptoms were observed to analyze renal damage.

Results: Using renal biopsy data from 329 cases, this study found that the most common pathological subtype in HBV-GN was mesangioproliferative glomerulonephritis (MsPGN) (24.

Establishment of a mouse IgA nephropathy model with the MBP-20-peptide fusion protein.

Here, we aimed to determine whether immunoglobulin-A nephropathy (IgAN) could be induced in Balb/c mice by immunizing them with a fusion protein (MBP-20 peptide) comprising the maltose-binding protein (MBP) and a 20-amino-acid peptide derived from Staphylococcus aureus. A recombinant plasmid encoding the fusion protein was constructed and expressed in bacterial cells. The synthetic 20-peptide was used to prepare the monoclonal antibody.
