Sphingolipid biosynthesis modulates plasmodesmal ultrastructure and phloem unloading [PDF]

, 2019
During phloem unloading, multiple cell-to-cell transport events move organic substances to the root meristem. Although the primary unloading event from the sieve elements to the phloem pole pericycle has been characterized to some extent, little is known about post-sieve element unloading. Here, we report a novel gene, PHLOEM UNLOADING MODULATOR (PLM),

Organochloride pesticides impaired mitochondrial function in hepatocytes and aggravated disorders of fatty acid metabolism

Scientific Reports, 2017
p,p’-dichlorodiphenyldichloroethylene (p, p’-DDE) and β-hexachlorocyclohexane (β-HCH) were two predominant organochlorine pesticides (OCPs) metabolites in human body associated with disorders of fatty acid metabolism.

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

The combinatorial multitude of fatty acids can be described by Fibonacci numbers [PDF]

arXiv, 2013
The famous series of Fibonacci numbers is defined by a recursive equation saying that each number is the sum of its two predecessors, with the initial condition that the first two numbers are equal to unity. Here, we show that the numbers of fatty acids (straight-chain aliphatic monocarboxylic acids) with n carbon atoms is exactly given by the ...

LNMICC Promotes Nodal Metastasis of Cervical Cancer by Reprogramming Fatty Acid Metabolism.

Cancer Research, 2017
Cancer spread to lymph nodes predicts poor survival but underlying mechanisms remain little understood. In this study, we show that overexpression of the long noncoding RNA LNMICC associates with lymph node metastasis of primary cervical cancer, where it

Pharmacological effects of osimertinib on a chicken chorioallantoic membrane xenograft model with the EGFR exon‐19‐deleted advanced NSCLC mutation

FEBS Open Bio, EarlyView.
Osimertinib reduces angiogenesis and PDL1 expression in in ovo tumors, transforming them into ‘cold tumors’ with lower immune activity. Anatomopathological and transcriptomic analyses highlight its therapeutic impact on tumor biology. This study underscores osimertinib's potential to reshape the tumor microenvironment and provides insights into its ...

Oroxylin A suppresses the development and growth of colorectal cancer through reprogram of HIF1α-modulated fatty acid metabolism

Cell Death and Disease, 2017
The occurrence and progress of colon cancer are closely associated with obesity. Therefore, the lipid metabolism, especially fatty acid metabolism, is a significant section of energy homeostasis in colon cancer cells, and it affects many important ...

Tryptophan‐sensing receptor GPR142 expression levels are directly regulated by proinflammatory cytokines in ghrelin‐producing cells

FEBS Open Bio, EarlyView.
GPR142, a tryptophan‐sensing receptor, stimulates gastrointestinal hormones like ghrelin and is linked to inflammation regulation. Proinflammatory cytokines suppress ghrelin production, while tryptophan levels decrease via IDO1 activation. Our findings reveal that proinflammatory cytokines directly regulate GPR142 expression in ghrelin‐producing cells,

Impurity contribution to ultraviolet absorption of saturated fatty acids [PDF]

Science Advances 9 (2023) eadj6438
Saturated fatty acids are abundant organic compounds in oceans and sea sprays. Their photochemical reactions induced by solar radiation have recently been discovered as an abiotic source of volatile organic compounds, which serve as precursors of secondary organic aerosols.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria

FEBS Open Bio, EarlyView.
The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.
