Although the prognosis of breast cancer has significantly improved compared to other types of cancer, there are still some patients who expire due to recurrence or metastasis. Therefore, it is necessary to develop a method to identify patients with poor prognosis at the early stages of cancer. In the process of discovering new prognostic markers from genes of unknown function, we found that the expression of C1orf50 determines the prognosis of breast cancer patients, especially for those with Luminal A breast cancer.

Background: The Japan Clinical Oncology Group (JCOG) 1006 was a phase III trial of patients with clinical T3/T4 colon cancer comparing the no-touch isolation technique ('No Touch') with the conventional technique ('Conventional'). The planned primary analysis at 3 years failed to confirm the superiority of the No Touch over the 'Conventional'. The present study aimed to compare the 'No Touch' and 'Conventional' using long-term (6-year) follow-up data.

Article Synopsis
  • - Carbohydrate antigen 19-9 (CA19-9) is a clinically established biomarker for pancreatic ductal adenocarcinoma (PDAC) but is not very effective for early detection, prompting the exploration of circulating miRNAs in plasma as potential early biomarkers.
  • - A study analyzed 2083 miRNAs from patients and healthy controls, identifying a three-miRNA signature (let-7i-5p, miR-130a-3p, and miR-221-3p) that effectively distinguished early-stage PDAC from healthy individuals and chronic pancreatitis, showing improved accuracy when combined with CA19-9.
  • - The miRNA signature demonstrated high predictive accuracy in various stages of the disease and

Cadmium is a contributing factor to cardiovascular diseases and highly toxic to vascular endothelial cells. It has a distinct mode of injury, causing the de-endothelialization of regions in the monolayer structure of endothelial cells in a concentration-dependent manner. However, the specific molecules involved in the cadmium toxicity of endothelial cells remain unclear.

Introduction: Glycosylation, the process of glycan synthesis and attachment to target molecules, is a crucial and common post-translational modification (PTM) in mammalian cells. It affects the protein's hydrophilicity, charge, solubility, structure, localization, function, and protection from proteolysis. Aberrant glycosylation in proteins can reveal new detection and therapeutic Glyco-biomarkers, which help to improve accurate early diagnosis and personalized treatment.
