Intestinal epithelial stem/progenitor cells are controlled by mucosal afferent nerves. [PDF]

PLoS ONE, 2011
BACKGROUND: The maintenance of the intestinal epithelium is of great importance for the survival of the organism. A possible nervous control of epithelial cell renewal was studied in rats and mice.

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

Advanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Topoisomerase I Inhibition in ETV4‐overexpressed Non‐Small Cell Lung Cancer Promotes Replication and Transcription Mediated R‐Loop Accumulation and DNA Damage

Advanced Science, EarlyView.
The oncogenic ETS factor ETV4 exerts a pleiotropic control over DNA replication both in a transcription‐dependent and ‐independent fashion in NSCLC cells. High‐ETV4 expression leads to R‐loop formation and DNA damage in response to TOP1 inhibition.

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

Advanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Utilization of exogenous thymidine by Chlamydia psittaci growing in the thymidine kinase-containing and thymidine kinase-deficient L cells [PDF]

Journal of Bacteriology, 1976
The incorporation of [3H]thymidine into the deoxyribonucleic acid (DNA) of Chlamydia psittaci (strain 6BC) growing in thymidine kinase (adenosine 5'-triphosphate-thymidine 5'-phosphotransferase, EC 1.7.1.21)-containing L cells, L(TK+), and thymidine kinase-deficient L cells, LM(TK-), was examined by autoradiography. Label was detected over C.

Phosphorylation‐Dependent Stabilization of Collaborator of ARF (CARF) Suppresses Lymphoma Cell Proliferation

Advanced Science, EarlyView.
This study revealed that oncogene Collaborator of ARF (CARF) is closely related to B‐cell lymphoma tumorigenesis, and shares a conserved mechanism regulating protein stability with Arabidopsis Kip‐Related Protein6 (KRP6) through casein kinase 1‐mediated phosphorylation. Reduced phosphorylation led to the enhanced protein stability of CARF, resulting in

Deoxypyrimidine monophosphate bypass therapy for thymidine kinase 2 deficiency

EMBO Molecular Medicine, 2014
Autosomal recessive mutations in the thymidine kinase 2 gene (TK2) cause mitochondrial DNA depletion, multiple deletions, or both due to loss of TK2 enzyme activity and ensuing unbalanced deoxynucleotide triphosphate (dNTP) pools.

STAT6 Activation Exacerbates Ferroptosis in Airway Epithelium by Inhibiting PRKN‐Mediated Mitophagy in Pulmonary Fibrosis

Advanced Science, EarlyView.
This study uncovers STAT6‐driven pulmonary fibrosis (PF) via suppression of PRKN‐mediated airway epithelial mitophagy, triggering mitochondrial dysfunction and ferroptosis. Rifabutin is identified as a potent STAT6 inhibitor that effectively reverses fibrotic progression. These findings reveal the STAT6‐PRKN axis as a pathogenic regulator and provide a

ATF3 Deficiency Exacerbates Ageing‐Induced Atherosclerosis and Clinical Intervention Strategy

Advanced Science, EarlyView.
Targeting ATF3 with terazosin to against VSMC Senescence and atherosclerosis. TZ reduces the binding affinity of YTHDF2 to Atf3 mRNA, while enhancing mRNA stability. ATF3 promotes Atg7 transcription, enhancing autophagy. ATG7 binds to ATF3 in the cytoplasm, facilitating ATF3 translocation to the nucleus and establishing positive feedback. By modulating
