SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Two-stage co-pyrolysis of Kraft lignin and palm oil mixture to biofuels: The role of lignin as a methylation agent for methyl ester formation

open access: yesFuel Processing Technology
In this work pyrolysis of palm oil and lignin has been investigated using a two-stage process at 550 °C, with a first step configuration of continuous condensation for vapors and separation of gases, and a second step with distillation of vapors ...

Long-term effects of cis and trans monounsaturated (18:1) and saturated (16:0) fatty acids on the synthesis and secretion of apolipoprotein A-I- and apolipoprotein B-containing lipoproteins in HepG2 cells

open access: yesJournal of Lipid Research, 2000
The objective of this study was to compare the long-term effects of oleic (cis 18:1), elaidic (trans 18:1), and palmitic (16:0) acids on hepatic lipoprotein production, using HepG2 cells as an experimental model.

TrxR2 Lactylation Facilitates Mitochondrial Protection and Endothelial Ferroptosis Resistance in Diabetic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
TrxR2 deletion in diabetic mice suppresses TUFM‐AMPK‐FUNDC1‐dependent mitophagy in endothelial cells, resulting in SCP2 upregulation and mitochondrial translocation of ACSL4. Mitochondrial ACSL4 promotes mitochondrial eicosanoid biosynthesis and ferroptosis, thereby aggravating cardiac microvascular injury and diabetic cardiomyopathy.

Systemic Metabolomic Changes in Blood Samples of Lung Cancer Patients Identified by Gas Chromatography Time-of-Flight Mass Spectrometry. [PDF]

open access: yes, 2015
Lung cancer is a leading cause of cancer deaths worldwide. Metabolic alterations in tumor cells coupled with systemic indicators of the host response to tumor development have the potential to yield blood profiles with clinical utility for diagnosis and ...

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

open access: yesAdvanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...

Effects of increasing dietary palmitoleic acid compared with palmitic and oleic acids on plasma lipids of hypercholesterolemic men.

open access: yesJournal of Lipid Research, 1994
Palmitoleic acid is a minor monounsaturated fatty acid in the human diet and in blood plasma. Because macadamia oil is at least one potentially large source of palmitoleic acid, we tested its effect on plasma lipid levels against two other dietary fatty ...

Synergistic interaction of fatty acids and oxysterols impairs mitochondrial function and limits liver adaptation during nafld progression [PDF]

open access: yes, 2018
The complete mechanism accounting for the progression from simple steatosis to steatohepatitis in nonalcoholic fatty liver disease (NAFLD) has not been elucidated.

Polyphenol‐Based Biomaterials Against Cancer Radio/Chemotherapy‐Induced Intestinal Toxicity

open access: yesAdvanced NanoBiomed Research, EarlyView.
Radiotherapy/chemotherapy often causes intestinal toxicity, impairing cancer patients’ quality of life and treatment efficacy. Polyphenols protect against this injury via multiple mechanisms, but face oral use limitations. This review outlines their protective mechanisms and delivery challenges, highlighting recent oral delivery advances and future ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...
