The thermal behavior of enzymes in nanoscale is of great significance to life phenomena. This nonequilibrium state real-time thermal behavior of enzymes at nanoscale cannot be accurately detected by existing methods. Herein, a novel method is developed for the detection of this thermal behavior.

Article Synopsis
  • The study focuses on the deep population history of East Asia, utilizing ancient DNA from 166 individuals to explore migration patterns and ancestry connections over millennia.
  • It identifies a significant coastal migration during the Late Pleistocene and notes expansions in the Holocene from regions like Mongolia, the Amur River Basin, and the Yellow River, affecting language distributions and genetic ancestry.
  • The findings suggest complex interactions involving different lineages, including shared ancestry among Mongolic and Tungusic speakers, a major genetic contribution to the Han Chinese from Yellow River farmers, and a mix of northern and southern ancestries in Taiwan.

Article Synopsis
  • The study examines the genetic diversity and ancestry of Mongolian and Kazakh populations, highlighting the ethnic variations based on geographic and tribal differences.
  • By analyzing over 690,000 genetic markers from individuals, researchers identified distinct genetic clusters in Mongolians and found significant ancestry from both West Eurasian and East Asian groups, particularly from Bronze Age and Neolithic populations.
  • The results suggest that the genetic landscape of these populations has been shaped by historical migrations, admixture events, and agricultural expansion over the past several centuries.

The miRNAs play important regulating roles in the pathogenesis of hepatocellular carcinoma (HCC). To uncover key regulating miRNAs in HCC that were neglected by traditional analyzing methods of transcriptomics data, we proposed a novel molecular-network-based omics' (MNBO) method. With this method, we predicted HCC-regulating miRNAs, and confirmed the role of a novel miR-590-3P/ axis by a clinical study and , wet-experiments.

Lung cancer is one of the most common causes of cancer-related death in the world. The large number of lung cancer cases is non-small cell lung cancer (NSCLC), which approximately accounting for 75% of lung cancer. Over the past years, our comprehensive knowledge about the molecular biology of NSCLC has been rapidly enriching, which has promoted the discovery of driver genes in NSCLC and directed FDA-approved targeted therapies.

Article Synopsis
  • Hepatocellular carcinoma (HCC) is a major health issue, ranking as the third leading cause of cancer-related deaths, with around 850,000 new cases each year, often diagnosed too late for surgical intervention.
  • The development of HCC is linked to various genetic "driver mutations" that enable cancer cells to thrive and are crucial for developing targeted therapies for patients with advanced stages of the disease.
  • This review highlights the current knowledge of driver mutations, identifies methods for discovering these genetic changes, and categorizes targeted drugs for HCC, emphasizing the potential for improved treatments through precision medicine.

Objectives: The Tibetan-Yi Corridor located on the eastern edge of Tibetan Plateau is suggested to be the key region for the origin and diversification of Tibeto-Burman speaking populations and the main route of the peopling of the Plateau. However, the genetic history of the populations in the Corridor is far from clear due to limited sampling in the northern part of the Corridor.

Materials And Methods: We collected blood samples from 10 Tibetan and 10 Han Chinese individuals from Gansu province and genotyped about 600,000 genome-wide single nucleotide polymorphisms (SNPs).

Sleep deprivation (SD) has been shown to induce anxiety-like behavior. Melatonin, an endogenous potent antioxidant, protects neurons from oxidative stress in many disease models. Here we investigated the effect of melatonin against SD-induced anxiety-like behavior and attempted to define the possible mechanisms involved.

Article Synopsis
  • A magnetic bead purification method was used to successfully extract ancient DNA from skeletal remains of 10 specimens from the Wuzhuangguoliang site in northern Shaanxi.
  • Analysis showed that the ancient Wzhgl population had a high genetic similarity to southern Han Chinese, and phylogenetic studies indicated close maternal relations with ancient populations from Shandong and Xinjiang.
  • The findings suggest that the Wzhgl people contributed to the genetic makeup of modern Han Chinese and Japanese populations, and there may have been migration and interaction between Wzhgl and ancient Shandong or Xinjiang groups during the Neolithic period.

Hepatocellular carcinoma (HCC) is a common and leading cause of death worldwide. Here, we identified that a cell-cell adhesion gene, CTNNA3, is a tumor suppressor in HCC. CTNNA3 inhibited the proliferation, migration and invasion of HCC cell lines.

Many genes change their transcription in atrial fibrillation (AF) patients, which indicates the functional relationship of these genes with AF. Thus, identifying the over-represented motifs in the upstream region of these genes would shed light on the mechanism of this disease. We analyzed a set of microarray experiments, selected from genes whose expression was changed, and extracted their regulatory sequences from genome databases.

Objectives: The purpose of this study was to assess the prevalence, distribution and intensity of dental caries as well as tooth wear in Neolithic population of northern China to increase our knowledge about the type of food, dietary habit and social stratification in this Neolithic population.

Materials And Methods: The samples analysed were dental remains of 1007 permanent teeth from 79 adult individuals, who were excavated from three Yangshao archaeological sites in the Xi'an district and adjacent Counties (northern China). The sex and the age-at-death of the samples were estimated.

Objective: Based on the sequence differences of Amelogenin homologous gene in the X and Y chromosomes, a pair of specific primers was designed to identify the sex of archaeological samples.

Methods: Ancient DNA fragments were extracted from the bones and teeth of sacrificial slaves with an improved method that combines phenol-chloroform extraction, silicon dioxide adsorption with ultrafiltration concentration. The polyacrylamide gel electrophoresis (PAGE) was used to detect PCR products.
