Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

open access: yesFEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Mass media and climate change

open access: yes
The paper shows the mass media perspectives regarding the climate events in the last 150 years. The authors identified three periods, a warmer one between the 1920s - 1930s, a colder one between the 1960s - 1980s, and again a warmer one between the 1990s - present, in which the press of the time made serious, imperative, threatening statements about ...

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

open access: yesFEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

open access: yesFEBS Open Bio, EarlyView.
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

open access: yesFEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...
