Loss of Fibronectin Fiber Tension in Glioblastoma is Associated with Microvascular Proliferations and Immune Cell Infiltration

Advanced Science, EarlyView.
Researchers discovered that fibronectin fibers lose their tension in specific areas of glioblastoma brain tumors, accumulating in the lumen of proliferating blood vessels and in parenchyma next to infiltrating immune cell clusters. A novel molecular tension probe enables the mapping of fibronectin's fiber tension in glioblastoma for the first time ...

Somatic mutations, DNA methylation, and expression of DNA repair genes in Arabidopsis thaliana treated with 5-azacytidine

Biologia Plantarum, 2019
An inhibitor of DNA methylation 5-azacytidine (5A) is a chemical analog of the nucleoside cytidine. This study investigated the influence of 5A-induced DNA hypomethylation on the accumulation of somatic DNA mutations (nucleotide substitutions, indels) in

Steroid Receptor Coactivator‐1 Drives Tumor‐Associated Macrophage Reprogramming by Mediating MMP12 Transcription in Pancreatic Cancer Perineural Invasion

Advanced Science, EarlyView.
Steroid receptor coactivator‐1 (SRC‐1) reprograms tumor‐associated macrophages (TAMs) via signal transducer and activator of transcription 1(STAT1)‐mediated matrix metallopeptidase 12 (MMP12) transcription to drive perineural invasion (PNI) in pancreatic cancer.

RAD21L1 Is Sufficient and Effective for Reprogramming Human Sertoli Cells to Phenotypic Spermatogonial Stem Cells Through DNA Methylation and Essential for Male Fertility

Advanced Science, EarlyView.
RAD21L1 is upregulated in human Sertoli cells to be transited to become spermatogonial stem cells by overexpressing DAZ family three genes. RAD21L1 is sufficient and effective for reprogramming Sertoli cells into human spermatogonial stem cells with high safety through DNA methylation.

Mutational Analysis Reveals Functional Roles of METTL16 Domains and Residues

Biology
Human methyltransferase-like protein 16 (METTL16) installs N6-methyladenosine on U6 small nuclear RNA (snRNA) and other RNAs. Multiple X-ray crystal structures of METTL16 have been published; however, we do not yet fully understand the structure–function

The activity of a yeast Family 16 methyltransferase, Efm2, is affected by a conserved tryptophan and its N‐terminal region

FEBS Open Bio, 2016
The Family 16 methyltransferases are a group of eukaryotic nonhistone protein methyltransferases. Sixteen of these have recently been described in yeast and human, but little is known about their sequence and structural features.

Structural insights into the RNA methyltransferase domain of METTL16

Scientific Reports, 2018
N6-methyladenosine (m6A) is an abundant modification in messenger RNA and noncoding RNAs that affects RNA metabolism. Methyltransferase-like protein 16 (METTL16) is a recently confirmed m6A RNA methyltransferase that methylates U6 spliceosomal RNA and ...

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

Advanced Science, EarlyView.
Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket‐Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target

Advanced Science, EarlyView.
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...
