Aberrant methylation is one of the early detectable events in many tumors, which is very promising for pan-cancer early-stage diagnosis and prognosis. To efficiently analyze the big pan-cancer methylation data and to overcome the co-methylation phenomenon, a MapReduce-based distributed and parallel-designed partial least squares approach was proposed. The large-scale high-dimensional methylation data were first decomposed into distributed blocks according to their genome locations.

Article Synopsis
  • Hemicellulose, a common polysaccharide, can be broken down into xylose for conversion into fuels and chemicals, but the adaptation mechanism of engineered Saccharomyces cerevisiae (yeast) to utilize xylose is not well understood.
  • The study discovered that xylose consumption increased by 1.24 times after the yeast was adapted to a xylose-rich medium, and a phenomenon called "xylose consumption memory" was observed, indicating a reduced stagnation time for xylose utilization at the single-cell level.
  • Key findings include that the proteomic changes related to the xylose consumption memory involve differential acetylation at the H4K5 site and that knocking out certain acetylase genes (GCN5

Tobacco exposure is one of the major risks for the initiation and progress of lung cancer. The exact corresponding mechanisms, however, are mainly unknown. Recently, a growing body of evidence has been collected supporting the involvement of DNA methylation in the regulation of gene expression in cancer cells.

Radiotherapy is one of the most important cancer treatments, but its response varies greatly among individual patients. Therefore, the prediction of radiosensitivity, identification of potential signature genes, and inference of their regulatory networks are important for clinical and oncological reasons. Here, we proposed a novel multiple genomic fused partial least squares deep regression method to simultaneously analyze multi-genomic data.

Article Synopsis
  • Lung adenocarcinoma (LUAD) exhibits different carcinogenic mechanisms in smokers versus nonsmokers, highlighting the need for tailored therapies as the number of nonsmoking patients rises.
  • The study utilized three independent tumor sample sets and a novel selection method based on the partial least squares algorithm to identify gene patterns that distinguish between smokers and nonsmokers.
  • A total of 166 significant genes were found, achieving over 76% accuracy in classifying LUAD based on gene expression, emphasizing specific genetic patterns linked to nonsmokers.

Background: Antiviral drugs are widely used in populations with viral infection caused by immunologic inadequacy. Because these drugs are mainly metabolized by the kidneys, patients with renal failure undergoing renal replacement therapy are prone to drug adverse effects and poisoning. Severe neurotoxicity caused by antiviral drugs is a rare but life-threatening complication.

Renal cell carcinoma (RCC) is the most common renal carcinoma in the human kidney. To date, to the best of our knowledge, there are no biomarkers for the early monitoring and diagnosis of RCC patients. The present study aimed to develop deeper insight into the molecular mechanisms of microRNAs (miRNAs/miRs) in the regulation of RCC development and to reveal candidate miRNA biomarkers in human RCC.
