Altered carnitine transporter genes (, , ) expression pattern among lung cancer patients.

Background: Despite the decrease of morbidity rate of non-small cell lung cancer (NSCLC) in recent years, it is still a cancer with poor prognosis. Lung cancers (LCs) are usually diagnosed at a late stage of the disease due to non-specific clinical symptoms. Proper regulation of carnitine levels is important in the context of development and increased risk of cancer cells proliferation.

Gene Expression in Non-Small Cell Lung Cancer.

ATP-binding cassette subfamily G member 2 [ABCG2/breast cancer resistance protein (BCRP)] contributes to mechanisms of multidrug resistance (MDR) and is a marker of side population (SP) cells in human cancers. The primary objective of this study was to investigate the impact of gene expression on the non-small cell lung cancer (NSCLC) development, course of cancer disease, and patient prognosis using publicly available data. Obtained results were supplemented with assessment of expression in blood of NSCLC patients.

This study aimed to analyze publicly available bioinformatics data to elucidate the oncogenic role of genes in selected gastrointestinal cancers.

Carvacrol as a Stimulant of the Expression of Key Genes of the Ginsenoside Biosynthesis Pathway and Its Effect on the Production of Ginseng Saponins in Hairy Root Cultures.

The accumulation of ginsenosides (triterpenic saponins) was determined in hairy root cultures subjected to an elicitation process using carvacrol at 5, 10, 25, 50, 100, 250, and 500 μM concentrations during 24 and 72 h exposure. This study was the first one in which carvacrol was applied as an elicitor. The content of eight ginsenosides, Rb1, Rb2, Rb3, Rc, Rd, Rg1, Rg2, and Re, was determined using HPLC analysis.

Correlation of Gene Expression Axis Changes with Treatment Efficacy and Survival of NSCLC Patients.

In the course of lung cancer, normal cells are transformed into cancerous ones, and changes occur in the microenvironment, including the extracellular matrix (ECM), which is not only a scaffold for cells, but also a reservoir of cytokines, chemokines and growth factors. Metalloproteinases (MMPs) are among the elements that enable ECM remodeling. The publication focuses on the problem of changes in the gene expression of , and tissue inhibitor of metalloproteinases () in the blood of NSCLC patients during therapy (one year after surgical resection of the tumor).

Assessment of the Influence of 5-Fluorouracil on SMAD4 and TGFB1 Gene Expression, Apoptosis Induction and DNA Damage in Human Cell Lines.

Purpose: Suppressor of mothers against decapentaplegic homolog 4 (SMAD family member 4, ) is involved in the adenoma-carcinoma pathway, leading to the development of colon cancer. The encoded protein is a key downstream signaling mediator in the TGFβ pathway. This pathway has tumor-suppressor functions, including cell-cycle arrest and apoptosis.

Differential Expression of AP-2 Transcription Factors Family in Lung Adenocarcinoma and Lung Squamous Cell Carcinoma-A Bioinformatics Study.

Members of the activator protein 2 (AP-2) transcription factor (TF) family are known to play a role in both physiological processes and cancer development. The family comprises five DNA-binding proteins encoded by the to genes. Numerous scientific reports describe differential expression of these TF and their genes in various types of cancer, identifying among them a potential oncogene or suppressor like or .

Molecular Pathogenesis of Fibrosis, Thrombosis and Surfactant Dysfunction in the Lungs of Severe COVID-19 Patients.

The global scope and scale of the SARS-CoV-2 pandemic led to huge amounts of important data from clinical observations and experimental analyses being collected, in particular, regarding the long-term impact of COVID-19 on lung tissue. Visible changes in lung tissue mainly relate to the destruction of the alveolar architecture, dense cellularity, and pulmonary fibrosis with myofibroblast proliferation and collagen deposition. These changes are the result of infection, mainly with virus variants from the first pandemic waves (Alpha to Delta).

Importance of selected ABCB1 SNPs for the level of severity of depressive symptoms and effectiveness of recurrent depressive disorder therapy.

The expression level of mRNA and also the function of P-gp are strictly connected with the polymorphic nature of the ABCB1 gene. In this study, we evaluated the association between promoter SNP, i.e.

The Microbiota-Gut-Brain Axis in Psychiatric Disorders.

Modulating the gut microbiome and its influence on human health is the subject of intense research. The gut microbiota could be associated not only with gastroenterological diseases but also with psychiatric disorders. The importance of factors such as stress, mode of delivery, the role of probiotics, circadian clock system, diet, and occupational and environmental exposure in the relationship between the gut microbiota and brain function through bidirectional communication, described as "the microbiome-gut-brain axis", is especially underlined.

A potential link between AQP3 and SLC14A1 gene expression level and clinical parameters of maintenance hemodialysis patients.

Background: The transport of water and urea through the erythrocyte membrane is facilitated by aquaporins such as aquaglyceroporin (AQP3), and type B urea transporters (UT-B). As they may play an important role in osmotic balance of maintenance hemodialysis (HD) patients, the aim of the present study was to determine whether any relationship exists between the expression of their genes and the biochemical / clinical parameters in HD patients.

Methods: AQP3 and UT-B (SLC14A1) gene expression was evaluated using RT-qPCR analysis in 76 HD patients and 35 participants with no kidney failure.

and Genes Expression Level in Adult Acute Lymphoblastic Leukemia-A Case Control Study.

The genetic factors of adult acute lymphoblastic leukemia (ALL) development are only partially understood. The Runt-Related Transcription Factor () gene family play a crucial role in hematological malignancies, serving both a tumor suppressor and promoter function. The aim of this study was the assessment of relative and genes expression level among adult ALL cases and a geographically and ethnically matched control group.

Changes in the expression of membrane type-matrix metalloproteinases genes (MMP14, MMP15, MMP16, MMP24) during treatment and their potential impact on the survival of patients with non-small cell lung cancer (NSCLC).

The analysis concerned the comparison of the expression of membrane type matrix metalloproteinases genes in the blood and tissue of NSCLC patients during the course of the disease and comparison to the control group. Blood and neoplastic tissue taken from 45 patients diagnosed with non-small cell lung cancer was a research material. The expression level of MMP14, MMP15, MMP16 and MMP24 was evaluated by qPCR and the results were compared with controls.

Preliminary investigation of two promoter region polymorphisms of the gene in patients with recurrent depressive disorder.

Immune system dysregulation plays a role in the pathogenesis of complex human diseases, including psychiatric disorders. In addition, elevated levels of pro-inflammatory cytokines, including tumor necrosis factor α (TNF-α) may be conditioned by the presence of specific polymorphic variants. The present case-controlled preliminary study evaluated the prevalence of gene single nucleotide polymorphisms (SNPs) G-308A (rs1800629) and T-1031C (rs1799964) in 83 Polish patients with depression by restriction fragment length polymorphism analysis.

The most common mental illness is depression; however, its pathogenesis is not fully understood. One of the factors that may influence its development and the effectiveness of therapy are the cytochromes of the p450 complex. CYP3A5 and CYP2C19 are involved in the metabolism of drugs used in the treatment of depression.

Association between the CEBPA and c-MYC genes expression levels and acute myeloid leukemia pathogenesis and development.

CEBPA and c-MYC genes belong to TF and play an essential role in hematologic malignancies development. Furthermore, these genes also co-regulate with RUNX1 and lead to bone marrow differentiation and may contribute to the leukemic transformation. Understanding the function and full characteristics of selected genes in the group of patients with AML can be helpful in assessing prognosis, and their usefulness as prognostic factors can be revealed.
