Summary: Gemcitabine resistance in pancreatic ductal adenocarcinoma cells is associated with decreased energy production, decreased mitochondrial reactive oxygen species levels, and increased stemness caused by mitochondrial damage. Hypoxia may promote this process. Treatment with lauric acid restores gemcitabine sensitivity by activating oxidative phosphorylation. Further clinical validation of lauric acid in gemcitabine resistance is needed in the future.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with a poor prognosis and inadequate response to treatment. Multiple factors contribute to therapeutic failure, including late diagnosis due to lack of symptoms, early spread, advanced age of patients, hyperfibrotic stroma, genetic heterogeneity, and early resistance to available treatments.

Summary: This study reveals that endothelial cell focal adhesion kinase (FAK) plays a role in regulating pancreatic ductal adenocarcinoma (PDAC) metastasis and impacting the outcome of gemcitabine treatment. The findings suggest the potential clinical utility of combinatorial endothelial cell FAK targeting with gemcitabine in controlling metastasis in PDAC patients.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is a deadly malignancy with high chemoresistance. Gemcitabine, one of the primary treatments for PDAC, has limited benefits due to interactions with the tumor microenvironment (TME). Preclinical models have shown that certain schedules of gemcitabine administration can modulate the TME without promoting resistance. Metronomic therapy is a promising strategy to overcome barriers in PDAC treatments.

Summary: This study identified RETSAT as a novel replication fork protein in pancreatic ductal adenocarcinoma (PDAC) cells. RETSAT functions by interacting with DDX39B to promote fork restarting and increase cellular resistance to replication stresses co-induced by tumor environmental hypoxia and gemcitabine.

Summary: LINC00460 is associated with the response to gemcitabine in PDAC patients and PDAC-PDX, and it influences the activity of growth factors and extracellular matrix in PDAC tumor cells. LINC00460 directly binds to PDAP1 and regulates the cellular communication between PDAC tumor cells and CAFs through the PDAP1/PDGFA/PDGFR signaling pathway, thereby affecting the gemcitabine-resistance function of CAFs. PDAC-PDX tumors with lower expression of LINC00460 show a better response to gemcitabine plus crenolanib treatment.

Summary: This study identified OXCT1 as a key gene leading to GEM resistance in PDAC through the NF-kappa B signaling pathway, with high OXCT1 expression associated with shorter relapse-free survival under GEM treatment. OXCT1 overexpression in PDAC cell lines inhibited apoptosis after GEM treatment, and blocking the NF-kappa B signaling pathway reduced GEM resistance. These findings suggest that OXCT1 could be a potential therapeutic target for patients with PDAC.

Summary: Obesity is closely associated with pancreatic health, and obese individuals have an increased risk for developing pancreatic ductal adenocarcinoma (PDAC). Factors such as chronic inflammation, insulin resistance, metabolic dysfunction, immune suppression, hormone level changes, and genetic mutations contribute to the development and progression of PDAC in obese individuals.

Summary: This study investigated the spatiotemporal variations of terrestrial evapotranspiration (ET) in China from 2000 to 2019 and analyzed the driving factors behind these changes. The results showed that climate variation, including increasing precipitation and wind speed, had a significant impact on ET. The study also found that increasing temperature, decreasing sunshine duration and relative humidity contributed to the increase in ET to some extent. The findings provide valuable insights into the role of climate variability in hydrological processes and the potential impacts of ET variability on the climate system.

Summary: This study investigates the effects of in-cylinder steam injection (ICSI) on a liquefied petroleum gas (LPG) engine. The results show that steam decreases the laminar flame speed of LPG, while ICSI leads to significant increases in flame development angle and rapid burning angle. By adjusting the ignition timing, ICSI affects the combustion phase of the engine, and with optimum ignition timing, the engine performance and NO characteristic are remarkably improved.

Summary: Structurally well-defined arenes with higher numbers of linearly-fused six-member rings are important and desirable due to their experimental challenges and fundamental interests. In this research, a novel large N-heteroarene (N20) with 20 linearly-fused six-membered rings was successfully synthesized and confirmed by single-crystal X-ray diffraction analysis. The as-prepared arene exhibits a wave-like framework and shows high molar absorptivity and extended fluorescence in the near-infrared region.

Summary: A micro-structured CVD diamond micro-grinding tool was studied to improve lubrication and chip removal performance in the grinding zone. First, the effects of micro-structure parameters on the deformation and stress distribution of the micro-grinding tool were analyzed using a commercial FEM software. Then, the coolant flow fields in the grinding zone, including the macro flow field, micro flow field, and chip evacuation, were simulated. The effects of micro-structure parameters and grinding parameters on flow field performance and chip transport capacity were obtained, providing a basis for the design and optimization of surface micro-structures in CVD diamond micro-grinding tools.

Summary: The authors demonstrate that mechanochemical Scholl reaction provides a direct route to chlorinated curved nanographenes from graphitization precursors. The chlorination is regioselective, high-yielding, and general. The resulting nanographenes can be chemically modified with precision through Suzuki or nucleophilic aromatic substitution reactions, leading to modulation of material properties via edge modification.

Summary: ITGBL1 is highly expressed in pancreatic cancer tissues and is associated with poor prognosis. Silencing ITGBL1 inhibits cell proliferation, migration, and invasion, and delays the cell cycle, while overexpressing ITGBL1 has the opposite effect. ITGBL1 also activates the TGF-β/Smad pathway in pancreatic cancer progression. Additionally, JDP2 suppresses the expression of ITGBL1.
