J Biochem Mol Toxicol

October 2024

Department of Thyroid and Breast Surgery, The Fourth Affiliated Hospital, Guangzhou Medical University, Guangzhou, China.

Article Synopsis
  • This study explores the role of lysine-specific histone demethylase 1A (KDM1A) in triple-negative breast cancer (TNBC), revealing that KDM1A is highly expressed in TNBC tissues and contributes to cancer cell survival and aggressiveness.* -
  • The research shows that the protein ubiquitin-specific protease 1 (USP1) stabilizes KDM1A, and its depletion reduces KDM1A levels, ultimately inhibiting TNBC progression.* -
  • Additionally, Yin Yang 1 (YY1) is identified as a key regulator that increases KDM1A expression by binding to its promoter, highlighting the interconnected roles of YY1, KDM1A, and

Article Synopsis
  • Decoding brain states using fMRI data is a hot topic, but existing methods struggle with the temporal relationships in the data due to limitations in machine learning techniques and sample organization.
  • The researchers introduced a new method called Group-DBRNN, which improves brain state decoding by using a specialized sample organization strategy and a bidirectional recurrent neural network to better capture temporal dependencies.
  • Testing on a comprehensive dataset showed that their model achieved a high accuracy of 94.7% in identifying different brain states, demonstrating its effectiveness in handling temporal dynamics and task-related differences in brain activity.

Electronic address:

Propose: To establish a dynamic topography analysis method which simulates the dynamic biomechanical response of the cornea and reveals the variations of such response within the corneal surface, and thereafter to propose and clinically evaluate new parameters for the definite diagnosis of keratoconus.

Methods: 58 normal (Normal) and 56 keratoconus (KC) subjects were retrospectively included. Personalized corneal air-puff model was established using corneal topography data by Pentacam for each subject, and the dynamic deformation under air-puff loading was simulated using finite element method, which then enabled calculations of corneal biomechanical parameters of the entire corneal surface along any meridian.
