TGF-β induces EMT in thyroid cancer cells by regulating transcription factors.

Background: Transforming growth factor-β (TGF-β) plays well-established roles in cancer cell invasion and epithelial-mesenchymal transition (EMT); however, its role in thyroid carcinoma (TC) remains unclear. This study aimed to evaluate the effects of TGF-β on EMT in TC and determine its underlying mechanisms.

Methods: Treatment of TC cell lines with TGF-β the morphology of thyroid cancer cells changed, Immunofluorescence staining revealed that the localization of E-cadherin shifted from the cell membrane to the cytoplasm, and the fluorescence intensity decreases.

Synergistic effect of β-ocimene on Hyphantria cunea sex pheromone and its potential attraction mechanism related to Ca stimulation.

Hyphantria cunea, a globally significant quarantine pest, causes severe ecological and economic impacts in invaded regions. Attractants are environment-friendly and valuable pest management tools for H. cunea control.

Elevated circulating homocysteine concentrations delayed nerve conduction velocity and increase the risk of diabetic kidney disease in patients with type 2 diabetes.

Introduction: China has the largest population of individuals with diabetes, and the prevalence of various complications among patients with type 2 diabetes remains high. Diabetic nephropathy affects approximately 20% to 40% of diabetic patients, becoming a major cause of chronic kidney disease and end-stage renal disease. Furthermore, around 50% of patients develop diabetic peripheral neuropathy (DPN), which is closely associated with physical disability, increased healthcare costs, and reduced work productivity.

Systemic treatment options for non-small cell lung cancer after failure of previous immune checkpoint inhibitors: a bayesian network meta-analysis based on randomized controlled trials.

Background: Although immune checkpoint inhibitors (ICIs) have brought survival benefits to non-small cell lung cancer (NSCLC), disease progression still occurs, and there is no consensus on the treatment options for these patients. We designed a network meta-analysis (NMA) to evaluate systemic treatment options for NSCLC after failure of ICIs.

Methods: PubMed, Embase, Web of Science and Cochrane Library databases were searched, then literature screening was followed by NMA.

Mesoporous silica nanospheres-mediated insecticide and antibiotics co-delivery system for synergizing insecticidal toxicity and reducing environmental risk of insecticide.

Mesoporous silica nanoparticles (MSNs) are efficient carriers of drugs, and are promising in developing novel pesticide formulations. The cotton aphids Aphis gossypii Glover is a world devastating insect pest. It has evolved high level resistance to various insecticides thus resulted in the application of higher doses of insecticides, which raised environmental risk.

The gut symbiont Sphingomonas mediates imidacloprid resistance in the important agricultural insect pest Aphis gossypii Glover.

Background: Neonicotinoid insecticides are applied worldwide for the control of agricultural insect pests. The evolution of neonicotinoid resistance has led to the failure of pest control in the field. The enhanced detoxifying enzyme activity and target mutations play important roles in the resistance of insects to neonicotinoid resistance.

The influence of Bt cotton cultivation on the structure and functions of the soil bacterial community by soil metagenomics.

Bt cotton successfully controlled major devastating pests in cotton，such as Helicoverpa armigera and Spodoptera exigua, and led to a drastic decrease in insecticide use in cotton fields, and it has been grown commercially worldwide. However, Bt cotton cultivation left Bt toxin residues in the soil, resulting in a response by its microbiome that caused potential environmental risks. In this research, the metagenomics analysis was performed to investigate the structure and functions of the soil bacterial community in the Bt cotton field from the Binzhou, Shandong province of China, where the Bt cotton has been cultivated for over fifteen years.

The Expression of Transcription Factors is Different in Papillary Thyroid Cancer Cells during TNF - α induced EMT.

Proinflammatory factor tumor necrosis factor-α (TNF-α) is an important inflammatory mediators in tumor microenvironment and autoimmune diseases, it is highly expressed in many solid tumors and tumor microenvironment, showing a tumor promoting role. However, the molecular mechanisms underlying TNF-α-increased invasion of thyroid cancer are still not fully understood. In order to explore whether TNF-α plays a key role in the process of epithelial mesenchymal transition (EMT) in papillary thyroid carcinoma (PTC), we used TNF-α to induce EMT in different PTC cell lines, and observed the expression of different transcription factors and signal pathways.

Sublethal and lethal effects of the imidacloprid on the metabolic characteristics based on high-throughput non-targeted metabolomics in Aphis gossypii Glover.

Sublethal effect considered as an emerging factor to assess the environmental risk of insecticides, which can impact the insects on both physiology and behavior. Lethal exposure can be causing near immediate mortality. Pests are inevitably exposed to sublethal and lethal dose in the agroecosystem following application of pesticides.

Fitness costs of sulfoxaflor resistance in the cotton aphid, Aphis gossypii Glover.

Aphis gossypii Glover is an economically important pest of numerous crops throughout the world. Some field populations of A.gossypii in China have developed moderate level of resistance to sulfoxaflor, a newly released sulfoximine insecticide for management of sap-feeding pests.

Reproductive adaptation in alate adult morphs of the English grain aphid Sitobion avenae under starvation stress.

Adapting their reproductive physiology is a tactic that insects use in responding to conditions of food unavailability. The present study examined the potential effects of starvation periods on the ovarian development and reproduction of alate adult morphs of Sitobion avenae (Fabricius). Morphs both continuously fed and starved aphids contained two telotrophic ovaries, each comprising five ovarioles.

Knockdown of SETDB1 inhibits breast cancer progression by miR-381-3p-related regulation.

Background: SET domain bifurcated 1 (SETDB1) has been widely considered as an oncogene playing a critical role in many human cancers, including breast cancer. Nevertheless, the molecular mechanism by which SETDB1 regulates breast cancer tumorigenesis is still unknown.

Methods: qRT-PCR assay or western blot analysis was performed to assess the expression level of SETDB1 mRNA or protein, respectively.

Inflammatory mediators, tumor necrosis factor-α and interferon-γ, induce EMT in human PTC cell lines.

Inflammatory mediators, tumor necrosis factor (TNF)-α and interferon (IFN)-γ, promote adverse outcomes in numerous types of cancer; however, their role in papillary thyroid cancer (PTC) remains unclear. The aim of the present study was to investigate the influence of TNF-α and IFN-γ on the migration, invasion and epithelial-mesenchymal transition (EMT) of the three PTC cell lines, TPC-1, BCPAP and K1. The effect of TNF-α and IFN-γ on cell migration and invasion was assessed by wound-healing and Transwell assays.

Twist1 regulates the epithelial-mesenchymal transition via the NF-κB pathway in papillary thyroid carcinoma.

Expression of the oncogene Twist1 is correlated with tumor development and metastasis. Recent studies have suggested that the epithelial-to-mesenchymal transition (EMT) is necessary for tumor progression and metastases. Little is known concerning the role of Twist1 and EMT in thyroid cancer.
