Article Synopsis
  • Primary cilia are important organelles in tumor cells that help detect signals, and their precise role in response to ionizing radiation (IR) is still not well understood.
  • This study finds that IR increases the formation and length of primary cilia in tumor cells, with the process dependent on the dose and timing of radiation.
  • The research suggests that IR-induced ciliogenesis activates pathways that promote cellular senescence while inhibiting apoptosis, indicating that targeting cilia formation might improve the effectiveness of radiotherapy.

Background: Metabolic disorders were a health problem for many adults with congenital heart disease, however, the differences in metabolic syndrome-related metabolite levels in adults with congenital heart disease compared to the healthy population were unknown.

Methods: We collected 18 studies reporting metabolic syndrome-associated metabolite levels in patients with congenital heart disease. Data from different studies were combined under a random-effects model using Cohen's d values.

The emergence of a vaccine against hepatitis B has proven to be an important milestone in the prevention of this disease; however, 5%-10% of vaccinated individuals do not generate an immune response to the vaccine, and its molecular mechanism has not been clarified. In this study, single-cell RNA sequencing was performed on peripheral blood mononuclear cells (PBMCs) from three volunteers with a high immune response (HR) and three with no immune response (NR) to the hepatitis B vaccine. We found that the antigen-presenting activity scores of various antigen-presenting cells, the mitogen-activated protein kinase (MAPK) pathway activity scores of naive B cells, and the cell activity scores of three types of effector T cells were significantly decreased, whereas the cytotoxicity scores of CD3CD16KLRG1 natural killer T (NKT) cells were significantly increased in the NR group compared with those in the HR group.

Cyclin D1 (CCND1), a mediator of cell cycle control, has a G870A polymorphism which results in the formation of two splicing variants: full-length CCND1 (CCND1a) and C-terminally truncated CCND1 species (CCND1b). However, the role of CCND1a and CCND1b variants in cancer chemoresistance remains unknown. Therefore, this study aimed to explore the molecular mechanism of alternative splicing of CCND1 in breast cancer (BC) chemoresistance.

Phosphatase and tensin homolog () is one of the most important tumor suppressor genes. Although studies have shown the association between cancer and genetic polymorphisms of , the underlying molecular mechanisms of breast cancer (BC) chemosensitivity that results from polymorphism is still unclear. This study aims to investigate potential links between polymorphisms in cis-regulatory elements and BC chemosensitivity in the Chinese population.

The increasing intensity of environmental radiofrequency electromagnetic fields (RF-EMF) has increased public concern about its health effects. Of particular concern are the influences of RF-EMF exposure on the development of the brain. The mechanisms of how RF-EMF acts on the developing brain are not fully understood.

Thyroid hormones play a crucial role in midbrain dopaminergic (DA) neuron development. However, the underlying molecular mechanisms remain largely unknown. In this study, we revealed that thyroid hormone treatment evokes significant calcium entry through canonical transient receptor potential (TRPC) channels in ventral midbrain neural stem cells and this calcium signaling is essential for thyroid hormone-dependent DA neuronal differentiation.

With recent advances in the manufacture and application of nickel oxide nanoparticles (NiONPs), concerns about their adverse effects on the respiratory system are increasing. However, the underlying cellular and molecular mechanisms of NiONP-induced pulmonary toxicity remain unclear. In this study, we focused on the impacts of NiONPs on pulmonary inflammation and investigated whether the NLRP3 inflammasome is involved in NiONP-induced pulmonary inflammation and injury.

Background/aims: The purpose of this study was to explore the in vitro putative genotoxicity during exposure of Neuro-2a cells to radiofrequency electromagnetic fields (RF-EMFs) with or without silencing of 8-oxoG DNA glycosylase-1 (OGG1).

Methods: Neuro-2a cells treated with or without OGG1 siRNA were exposed to 900 MHz Global System for Mobile Communication (GSM) Talk signals continuously at a specific absorption rate (SAR) of 0, 0.5, 1 or 2 W/kg for 24 h.

Background: The laparoscopic approach has been proposed for treating hepatic cystic echinococcosis (HCE) and has already been used in clinical practice, mostly for non-radical operations. In this study, we aimed to evaluate the feasibility of total cystectomy of HCE under laparoscopy (LS).

Results: A retrospective review of the medical records obtained from 22 patients diagnosed with HCE between June 2009 and June 2013 and treated with an LS approach was conducted in the First Affiliated Hospital of Xinjiang Medical University.
