Progastrin Promotes Colorectal Cancer Stem Cell‐Like Properties via the Receptor PZR
The tumor microenvironment supports colorectal cancer (CRC) progression by maintaining cancer stem cells (CSCs) through progastrin (PG). This study identifies Protein Zero‐Related protein (PZR) as an essential receptor for PG activity, promoting CSC‐like signaling via SHP2/SRC/β‐catenin.

Mutagenic Improvement of Xylanase Production from Xylanolytic Bacteria and its Phylogenetic Analysis
This study was conducted to obtain xylanolytic mutants that have higher xylanase activity than their wildtype counterparts. A mutant with the best xylanolytic activity was selected and identified based on its 16S rRNA sequence.

A well-conserved Plasmodium falciparum var gene shows an unusual stage-specific transcript pattern [PDF]
The var multicopy gene family encodes Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) variant antigens, which, through their ability to adhere to a variety of host receptors, are thought to be important virulence factors.

The existence of Pin1 and Notch1 crosstalk is identified and verified in HCC, and the crucial function of this crosstalk in sustaining the aggressive phenotypes of CSCs and radioresistance. A biomimetic nanovesicle is now developed to block the crosstalk between Pin1 and Notch1 for inducing CSCs differentiation and sensitizing HCC radiotherapy ...

Mitochondrial DNA replication in sea urchin oocytes [PDF]
Mitochondrial DNA (mtDNA) replicative intermediates from Strongylocentrotus purpuratus oocytes were isolated by ethidium bromide-CsCl density gradient centrifugation and examined by electron microscopy after formamide spreading.

The study reveals that PAXIP1‐associated glutamate‐rich protein 1 (PAGR1), a glucose‐responsive regulator in skeletal muscle, modulates systemic glucose homeostasis and hepatic metabolism. Muscle‐specific PAGR1 deletion enhances insulin signaling, promotes glucose transporter 4 (GLUT4) translocation, and protects against high‐fat‐diet‐induced insulin ...

Aberrant Mitochondrial Metabolism in Alzheimer's Disease Links Energy Stress with Ferroptosis
Alves et al. reveal how energy loss and oxidative stress, two major features of Alzheimer's disease, are connected. Mitochondria controls the flux of the antioxidant glutathione (GSH), via facilitating both its production and consumption. Energy restriction limits GSH synthesis, conferring vulnerability to cell death by ferroptosis, implicated as a ...
