Hypoxic Cancer Cells-Derived Exosomes Strengthen the Development of Cancer Stem Cell-Like Properties Through Delivering LINC00665 in Thyroid Cancer Cells.

Hypoxia is a common phenomenon for solid tumors due to a lack of effective vascular system, and has been deemed as an important factor that drives the progression of thyroid cancer (TC) via altering the characteristics of tumor cells. The present study suggested that hypoxic TC cells enhanced cancer stem cell properties and progression of TC by delivering long intergenic non-protein coding RNA 665 (LINC00665)-containing exosomes. Specifically, TPC1 cells were exposed to normoxic or hypoxic environment, and it was found that hypoxic TPC1 cells-secreted exosomes (H-exo) were enriched with LINC00665, compared to normoxic TPC1 cells-derived exosomes (N-exo).

TRIM26 exacerbates pathological cardiac hypertrophy by activating TAK1.

Pathological myocardial hypertrophy can induce heart failure with high mortality, it is necessary to explore its pathogenesis. Tripartite motif-containing 26 (TRIM26) belongs to the multidomain E3 ubiquitin ligase family. We observed increased expression of TRIM26 in the myocardium of C57BL/6 mice subjected to transverse aortic constriction (TAC) surgery and neonatal rat cardiomyocytes (NRCMs) treated with phenylephrine (PE).

Causal associations of metabolic dysfunction-associated steatotic liver disease with gestational hypertension and preeclampsia: a two-sample Mendelian randomization study.

Background: Hypertensive disorders of pregnancy (HDPs), which include gestational hypertension (GH) and preeclampsia (PE), are the primary causes of maternal morbidity and mortality worldwide. Recent studies have found a correlation between metabolic dysfunction-associated steatotic liver disease (MASLD) and HDPs, but the causality of this association remains to be identified. Therefore, this study aims to evaluate the causal relationship between MASLD and HDPs through Mendelian randomization (MR) analysis.

MMP8-mediated vascular remodeling in pulmonary hypertension.

Pulmonary arterial hypertension (PAH) is a vascular remodeling disease that impacts the cardiopulmonary system. Due to the currently limited understanding of vascular remodeling, a cure for PAH remains elusive. This study highlights the critical role of the STAT1 (signal transducer and activator of transcription 1)/MMP8 (matrix metallopeptidase 8)/DRP1 (dynamin-related protein 1) axis in vascular remodeling and the pathogenesis of pulmonary hypertension.

N6-Methyladenosine Modification of PERP by RBM15 Enhances the Tumorigenesis of Lung Adenocarcinoma via p53 Signaling Pathway.

The promotive effect of P53 apoptosis effector related to PMP-22 (PERP) on lung adenocarcinoma (LUAD) has been confirmed. However, the N6-methyladenosine (m6A) modification of PERP to regulate LUAD progression have not been revealed. Bioinformatic analysis predicted the mechanism of PERP interacting with RBM15 and p53 pathway using GEPIA and The Cancer Genome Atlas (TCGA) databases.

Causal Relationships between Circulating Immune Cell Traits and the Risk of Rheumatoid Arthritis and Osteoarthritis: A Bidirectional Two-Sample Mendelian Randomization Study.

Background: Rheumatoid arthritis (RA) and osteoarthritis (OA) are prevalent chronic joint disorders with immunological pathogenesis. However, the causal relationships between circulating immune cells and them remain largely unknown. Therefore, we conducted a bidirectional two-sample Mendelian randomization (MR) study to determine their causal relationship.

Association of urban environments with Atherosclerotic cardiovascular disease: A prospective cohort study in the UK Biobank.

Urban environments and cardiovascular health are closely linked, yet only a few specific exposures have been explored in isolation and mostly adopting cross-sectional design. The influence of socioeconomic status and genetic predisposition also remains unclear. Hence, leveraging the UK Biobank data (n = 206,681), we conducted a prospective analysis of 213 urban environmental variables and their association with atherosclerotic cardiovascular disease (ASCVD).

Cascade-catalysed nanocarrier degradation for regulating metabolism homeostasis and enhancing drug penetration on breast cancer.

The abnormal structure of tumor vascular seriously hinders the delivery and deep penetration of drug in tumor therapy. Herein, an integrated and tumor microenvironment (TME)-responsive nanocarrier is designed, which can dilate vessle and improve the drug penetration by in situ releasing nitric oxide (NO). Briefly, S-nitroso-glutathione (GSNO) and curcumin (Cur) were encapsulatd into the Cu-doped zeolite imidazole framework-8 (Cu-ZIF-8) and modified with hyaluronic acid.

METTL3 methylated KIF15 promotes nasopharyngeal carcinoma progression and radiation resistance by blocking ATG7-mediated autophagy through the activation of STAT3 pathway.

Background: Resistance to radiotherapy is a major component in the failure of nasopharyngeal carcinoma (NPC) treatment. Enhancing autophagy in nasopharyngeal carcinoma may increase its radiation sensitivity, making it critical to find autophagy-modulating targets.

Methods: The level of KIF15 was determined in NPC patients.

Etomidate Inhibits Hepatic Ischemia-Reperfusion Injury Depending on the Activation of Nrf2-HO-1 Signaling Pathway.

Hepatic ischemia-reperfusion (I/R) injury (HIRI) is recognized as a local aseptic inflammatory response driven by innate immunity and is considered a leading cause of early organ dysfunction and failure following liver transplantation. Etomidate (Eto), an anesthetic drug known for its ability to inhibit inflammatory response and apoptosis, was the focus of our investigation. In this study, we conducted hepatic I/R surgery on C57 mice, analyzing liver damage through histopathology.

Causal relationship between circulating immune cells and gastric cancer: a bidirectional Mendelian randomization analysis using UK Biobank and FinnGen datasets.

Background: The role of immune cells in cancer pathogenesis remains controversial due to conflicting reports, potentially arising from various confounding factors. Emerging evidence suggests that cancer can also influence immune cell populations and functions, making it challenging to investigate their causal relationship. Traditional observational studies often fail to eliminate all confounding factors and are prone to reverse causality.

No genetic causal relationship between lung function and osteoporosis - evidence from a mendelian randomization study.

For a long time, the decline in lung function has been regarded as a potential factor associated with the risk of osteoporosis (OP). Although several observational studies have investigated the relationship between lung function and OP, their conclusions have been inconsistent. Given that Mendelian randomization (MR) studies can help reduce the interference of confounding factors on outcomes, we adopted this approach to explore the causal relationship between lung function and OP at the genetic level.

Type I Diabetes Mellitus impairs cytotoxic immunity through CEACAM5 upregulation in colorectal cancer : Exploring the intersection of autoimmune dysfunction and cancer progression: the role of NF-κB p65 in colorectal cancer.

Type 1 diabetes (T1D) is characterized by an autoimmune-mediated destruction of pancreatic beta cells and a chronic inflammatory state, which may influence the progression of colorectal cancer (CRC) through immune system dysregulation and enhanced tumor immune evasion. This study aims to elucidate the role of p65 in modulating the tumor microenvironment in CRC within the context of T1D and to determine how this modulation affects tumor growth, immune cell infiltration, and the expression of immune evasion molecules such as CEACAM5. NOD mice, which model T1D, were inoculated with MC38 colon carcinoma cells engineered to knock down p65.

METTL14-mediated m6A modification upregulated SOCS3 expression alleviates thyroid cancer progression by regulating the JAK2/STAT3 pathway.
