β-Thalassemia (β-thal) is one of the most common monogenic recessive inherited diseases worldwide. The mutation spectrum of β-thal has been increasingly broadened by various genetic testing methods. The discovery and identification of novel and rare pathogenic thalassemia variants enable better disease prevention, especially in high prevalence regions.

Protein post-translational modifications (PTMs) play an important role in different cellular processes. In view of the importance of PTMs in cellular functions and the massive data accumulated by the rapid development of mass spectrometry (MS)-based proteomics, this paper presents an update of dbPTM with over 2 777 000 PTM substrate sites obtained from existing databases and manual curation of literature, of which more than 2 235 000 entries are experimentally verified. This update has manually curated over 42 new modification types that were not included in the previous version.

The nonrigid point set registration is one of the bottlenecks and has the wide applications in computer vision, pattern recognition, image fusion, video processing, and so on. In a nonrigid point set registration problem, finding the point-to-point correspondences is challengeable because of the various image degradations. In this paper, a robust method is proposed to accurately determine the correspondences by fusing the two complementary structural features, including the spatial location of a point and the local structure around it.

Purpose: Our previous studies have shown that kinesin family member 11 (KIF11) is markedly overexpressed in human breast cancer cells or tissues and positively correlated with distant metastasis and prognosis in patients with breast cancer, suggesting an important role in the regulation of cancer stem cells. Herein, we examined the role of KIF11 in breast cancer stem cells.

Methods: In the current study, we validated our previous findings through analysis of data collected in The Cancer Genome Atlas.

MicroRNAs (miRNAs) are small non-coding RNAs (typically consisting of 18-25 nucleotides) that negatively control expression of target genes at the post-transcriptional level. Owing to the biological significance of miRNAs, miRTarBase was developed to provide comprehensive information on experimentally validated miRNA-target interactions (MTIs). To date, the database has accumulated >13,404 validated MTIs from 11,021 articles from manual curations.

The present study aimed to clarify the association between kinesin family member 11 (KIF11) and human breast cancer, and the effect of KIF11 on breast cancer cell progression. Western blot analysis, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis, retroviral infection, immunohistochemistry staining, MTT assay, anchorage-independent growth ability assay and tumorigenicity assay were all used in the present study. Western blot and RT-qPCR analysis revealed that the expression of KIF11 was markedly increased in malignant cells compared with that in non-tumorous cells at the mRNA and protein level.

Background: Pine needle oil from crude extract of pine needles has anti-tumor effects, but the effective component is not known.

Methods: In the present study, compounds from a steam distillation extract of pine needles were isolated and characterized. Alpha-pinene was identified as an active anti-proliferative compound on hepatoma carcinoma BEL-7402 cells using the MTT assay.

Article Synopsis
  • Chronic liver diseases are common in China, with a study in Jilin revealing a 17.53% prevalence of elevated alanine aminotransferase (ALT) levels, primarily due to non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome.
  • The study included 4,072 adults aged 18-79, showing that higher income, age, and certain health metrics like body mass index and fasting plasma glucose are significant risk factors for ALT elevation, particularly among female peasants and small businessmen.
  • Unlike metabolic disorders, elevated ALT levels related to hepatitis B or C infections were linked to gender, occupation, and age, highlighting the need for targeted health interventions in these demographics.

Background: Serum biochemical liver tests (LTs) (alanine aminotransferase, aspartate aminotransferase, and gamma glutamyltransferase) and platelet counts are often used to screen for chronic liver disease. We determined the prevalence and etiologies of abnormal LTs in an adult population in Jilin, China.

Methods: A total of 3791 individuals between the ages of 18 and 79 years were interviewed and then underwent ultrasonography and blood tests.

Objective: To investigate the characteristics of HCV genotypes of Han and Korean in Yanbian area of Jilin Province.

Methods: The HCV RNA load and genotypes of the 119 chronic hepatitis C patients in Yanbian area of Jilin Province were determined by real-time PCR and LiPA. The differences of the HCV genotypes in Han and Korean cases, in severity of the diseases, in HCV-RNA load, and in the relation with type 2 diabetes mellitus were analyzed.

Article Synopsis
  • The study investigates the immune response in cirrhosis caused by hepatitis B virus (HBV) and hepatitis C virus (HCV), focusing on lymphocyte subsets and cytokine levels.
  • It finds that cirrhotic patients exhibit a lower proportion of specific immune cells (like CD8+ T cells and NK cells) and an increase in others (like CD4+ T cells and Treg cells) compared to healthy individuals.
  • Additionally, while Th2 cytokine IL-6 levels are elevated in both HBV and HCV cirrhosis, only HBV patients show an increase in the Th1 cytokine IFN-gamma, indicating a shared immune deficiency regardless of the virus type.
