  • Scylla paramamosain, an important crab species in aquaculture, is increasingly threatened by the highly pathogenic mud crab dicistrovirus-1 (MCDV-1), which disrupts its cultivation due to viral diseases.
  • A study analyzed the immune response of infected mud crabs, revealing 5,139 differentially expressed genes and highlighting pathways related to humoral immunity that the crabs activate to combat MCDV-1, while also showing disruptions in metabolic processes.
  • The research identified 9 key hub genes linked to viral endocytosis, indicating that MCDV-1 may utilize this process to enter crab cells and replicate, marking a significant step in understanding the viral

Article Synopsis
  • Researchers studied how Marshall ethanol infusion (VOM-Et) helps when doing a specific heart procedure called mitral isthmus ablation for patients with a heart condition called atrial fibrillation.
  • They compared two groups: one that received VOM-Et alongside another treatment called radiofrequency (RF), and one that only received RF.
  • Results showed that the group with VOM-Et had a much higher success rate (96%) in blocking the intended area compared to the RF only group (76%), and certain factors like being male or older seemed to help the VOM-Et treatment work better.

Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease (ESRD) worldwide. Early detection is critical for the risk stratification and early intervention of progressive DKD. Serum creatinine (sCr) and urine output are used to assess kidney function, but these markers are limited by their delayed changes following kidney pathology, and lacking of both sensitivity and accuracy.

Hypoxia-inducible factors -1 (HIF-1) is a crucial transcription factor that regulates the expression of glycolytic genes. Our previous study proved that the Mud crab dicistrovirus-1 (MCDV-1) can induce aerobic glycolysis that favors viral replication in mud crab Scylla paramamosain. However, the role of HIF-1 on key glycolytic genes during the MCDV-1 infection has not been examined.

Aging is responsible for the main intrinsic triggers of cancers; however, the studies of aging risk factors in cancer animal models and cancer patients are rare and insufficient to be represented in cancer clinical trials. For a better understanding of the complex regulatory networks of aging and cancers, 8 candidate aging related long noncoding RNAs (CarLncs) identified from the healthy aging models, centenarians and their offsprings, were selected and their association with kidney renal clear cell carcinoma (KIRC) was explored by series of cutting edge analyses such as support vector machine (SVM) and random forest (RF) algorithms. Using data downloaded from TCGA and GTEx databases, a regulatory network of CarLncs-miRNA-mRNA was constructed and five genes within the network were screened out as aging related feature genes for developing KIRC prognostic models.

Article Synopsis
  • Prolyl hydroxylase 2 (PHD2) serves as the main oxygen sensor regulating HIF-1α stability, and researchers identified a novel PHD2 gene called SpPHD2 from the mud crab Scylla paramamosain, revealing its full transcript length of 1926 bp.
  • The SpPHD2 protein features key structural domains and is broadly expressed in various tissues, with its localization primarily in the cytoplasm.
  • Silencing SpPHD2 increased levels of SpHIF-1α and associated genes, while overexpression decreased SpHIF-1α activity; additionally, SpPHD2 expression rises under low oxygen conditions, suggesting a feedback loop in regulating hypoxia responses.

  • Triptolide (TPL) is a natural compound that could help treat many diseases, but it can also be harmful to the kidneys.
  • Scientists studied how TPL causes kidney damage by looking into the genes and molecules it affects in rats.
  • They found that a specific protein called c-Jun might be an important factor in TPL's harmful effects on the kidneys, and it might be connected to how our body’s clock works.

Ischemic stroke can cause blood-brain barrier (BBB) injury, which worsens brain damage induced by stroke. Abnormal expression of tight junction proteins in endothelial cells (ECs) can increase intracellular space and BBB leakage. Selective inhibition of mitogen-activated protein kinase, the negative regulatory substrate of mitogen-activated protein kinase phosphatase (MKP)-1, improves tight junction protein function in ECs, and genetic deletion of MKP-1 aggravates ischemic brain injury.

The CRISPR/Cas9 system has been successfully applied in dozens of diverse species; although the screening of successful CRISPR/Cas9 editing events remains particularly laborious, especially for those that occur at relatively low frequency. Recently, a co-CRISPR strategy was proved to enrich the desired CRISPR events. Here, the co-CRISPR strategy was developed in the Fall armyworm, Spodoptera frugiperda, with kynurenine 3-monooxygenase gene (kmo) as a marker.

MXene aerogels with a porous microstructure are a promising electromagnetic interference (EMI) shielding material due to its low density and excellent electrical conductivity, which has attracted widespread attention. Compared with traditional EMI shielding materials that rely on reflection as the primary mechanism, MXene aerogels with absorption as the dominant mechanism have greater potential for development as a novel EMI shielding material because of its ability to reduce environmental contamination from reflected electromagnetic (EM) waves from materials. In this study, a novel TiCT MXene/PEDOT:PSS hybrid aerogel was presented by freeze-drying and thermal annealing using few-layered TiCT MXene and the conductive polymer poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS).
