Cold Exposure Induces Intestinal Barrier Damage and Endoplasmic Reticulum Stress in the Colon via the SIRT1/Nrf2 Signaling Pathway

Frontiers in Physiology, 2022
Ambient air temperature is a key factor affecting human health. Long-term exposure to a cold environment can cause various diseases, while the impact on the intestine, the organ which has the largest contact area with the external environment, cannot be ...

Decreased glutathione biosynthesis contributes to EGFR T790M-driven erlotinib resistance in non-small cell lung cancer [PDF]

, 2016
Epidermal growth factor receptor (EGFR) inhibitors such as erlotinib are novel effective agents in the treatment of EGFR-driven lung cancer, but their clinical impact is often impaired by acquired drug resistance through the secondary T790M EGFR mutation.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Nrf2 Mutagenic Activation Drives Hepatocarcinogenesis [PDF]

Cancer Research, 2017
Abstract Nrf2, a master regulator of oxidative stress, is considered a prominent target for prevention of hepatocellular carcinoma (HCC), one of the leading causes of cancer-related deaths worldwide. Here we report that Nrf2-deficient mice resisted diethylnitrosamine (DEN)-induced hepatocarcinogenesis without affecting P450-mediated ...

Broccoli or Sulforaphane: Is It the Source or Dose That Matters?

Molecules, 2019
There is robust epidemiological evidence for the beneficial effects of broccoli consumption on health, many of them clearly mediated by the isothiocyanate sulforaphane.

Anti-Inflammatory activity of a polyphenolic extract from Arabidopsis thaliana in in vitro and in vivo models of Alzheimer's Disease [PDF]

, 2019
Alzheimer's disease (AD) is the most common neurodegenerative disorder and the primary form of dementia in the elderly. One of the main features of AD is the increase in amyloid-beta (Aβ) peptide production and aggregation, leading to oxidative stress ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

VA inhibits LPS-induced oxidative stress via modulating Nrf2/NF-κB-signalling pathways in bovine mammary epithelial cells

Italian Journal of Animal Science, 2019
The current study was conducted to examine the pre-protection effects of vitamin A (VA) on lipopolysaccharide (LPS)-induced oxidative damage in bovine mammary epithelial cells (BMECs) and to explore the antioxidant mechanisms of VA via nuclear factor ...
