Exometabolomic Analysis of Decidualizing Human Endometrial Stromal and Perivascular Cells

Differentiation of endometrial fibroblasts into specialized decidual cells controls embryo implantation and transforms the cycling endometrium into a semi-permanent, immune-protective matrix that accommodates the placenta throughout pregnancy. This process starts during the midluteal phase of the menstrual cycle with decidual transformation of perivascular cells (PVC) surrounding the terminal spiral arterioles and endometrial stromal cells (EnSC) underlying the luminal epithelium. Decidualization involves extensive cellular reprogramming and acquisition of a secretory phenotype, essential for coordinated placental trophoblast invasion. Secreted metabolites are an emerging class of signaling molecules, collectively known as the exometabolome. Here, we used liquid chromatography-mass spectrometry to characterize and analyze time-resolved changes in metabolite secretion (exometabolome) of primary PVC and EnSC decidualized over 8 days. PVC were isolated using positive selection of the cell surface marker SUSD2. We identified 79 annotated metabolites differentially secreted upon decidualization, including prostaglandin, sphingolipid, and hyaluronic acid metabolites. Secreted metabolites encompassed 21 metabolic pathways, most prominently glycerolipid and pyrimidine metabolism. Although temporal exometabolome changes were comparable between decidualizing PVC and EnSC, 32 metabolites were differentially secreted across the decidualization time-course. Further, targeted metabolomics demonstrated significant differences in secretion of purine pathway metabolites between decidualized PVC and EnSC. Taken together, our findings indicate that the metabolic footprints generated by different decidual subpopulations encode spatiotemporal information that may be important for optimal embryo implantation.

Effect of homonuclear boron bonds in the adsorption of DNA nucleobases on boron nitride nanosheets

Quantum-mechanics calculations were carried out within the density functional theory (DFT) scheme, to analyze the sorbate-sorbent interaction between DNA nucleobases (purines: guanine and adenine; pyrimidines: cytosine and thymine) and hexagonal boron nitride nanosheets (pristine and non-stoichiometric) in two phases: i) gas and ii) aqueous. The resulting molecular simulations for the pristine nanosheet indicate that the four molecular sorbates prefer to be oriented perpendicular and/or parallel respect to sorbent. This geometrical effect generates adsorption energies associated to non-covalent interactions (physisorption), being the preferential adsorption sites those of N atoms of the nanosheet. According to the calculated quantum descriptors, they exhibit low chemical reactivity and work function, as well as high polarity and semiconductor-like behavior. However, the homonuclear boron bonds in the nanosheet (negatively charged) induce a strong interaction, almost three times larger than pristine nanosheet in gas phase; except for cytosine, due to this is weakly adsorbed in both phases. Moreover, the chemical reactivity and work function are reduced, whereas its conductivity (energy LHgap) and polarity were increased, since the preferential interaction site is corresponding to a B atom. Since the magnetic behavior (1.0 bohr magneton) of BN nanosheet/rB is not altered, the nanosheets with homonuclear boron bonds might be used as potential drug delivery vehicles and sensors.

Does nocturnal activity prolong gecko longevity?

The majority of lizard clades are ancestrally and predominantly diurnal. The only major taxon in which most species are nocturnal is the Gekkota (geckos and pygopodids). As ectothermic thermoregulators, lizard metabolic rates are highly temperature dependent, and diurnal lizards therefore demonstrate higher metabolic rates than nocturnal ones. Furthermore, exposure to solar radiation is thought to reduce ectothermic longevity by increasing both metabolic costs and the rate of accumulating harmful mutations through UV radiation (UVC specifically). In being nocturnal, ectothermic species may reduce their intrinsic mortality rates and thus live longer. To test this hypothesis, we collected literature data on the maximum longevities of 740 lizard species, of which 185 are geckos. We examined whether geckos live longer than other lizards, and whether activity time affects gecko longevity. While geckos live relatively long for lizards of their size, their activity time was found to be unrelated to longevity, contradicting our predictions. We suggest that diurnal species may have evolved higher resistance to UV radiation via thicker, more keratinized skin. Elevated metabolic rates do not automatically equate with faster aging. Mortality through extrinsic causes (e.g., predation) may impose much stronger selective pressures than intrinsic causes.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 151266-23-8. Product Details of 151266-23-8.

A new utility of 1,3,3-tri(1H-indol-3-yl)propan-1-one as a precursor for synthesizing of oxoketene gem-dithiol and 1,2-dithiole-3-thione, using eco-friendly lemon juice as a catalyst

We have synthesized 1,3,3-tri(1H-indol-3-yl)propan-1-one (5) catalyzed by pure citrus lemon juice via direct alkylation reaction of indole (4) with chalcone (3) in an eco-friendly manner. The key synthon, alkylated indole (5) on treatment with carbon disulfide in an alkaline medium afforded the required oxoketene gem-dithiol (6). Treatment of the substrate (6) with some amines afforded pyrimidine derivatives (8) and/or (10). On subjecting oxoketene gem-dithiol (6) to reaction with phosphorus pentasulfide, it afforded 1,2-dithiole-3-thione derivative (11) as a novel synthesized compound. Cycloaddition reactions of 1,2-dithiole-3-thione (11) with quinones, and/or maleic anhydride in different reaction conditions were applied and furnished 2-(1,1,3-tri(1H-indol-3-yl)-3-thioxoprop-an-2-ylidene)-3a,7a-dihydrobenzo[d] [1,3]dithiole-4,7-dione (13); 2-(1,1,3-tri(1H-indol-3-yl)-3-thioxopropan-2-ylidene)dihydro-[1,3]dithiolo[4,5-c]furan-4,6-dione (15); 3-(di (1H-indol-3-yl)methyl)-3-(1H-indole-3-carbonothioyl)-2-thioxo-2,3,3a,7a-tetrahydro- benzo[b]thiophene-4,7-dione (16) and 3-(di(1H-indol-3-yl)methyl)-3-(1H-indole-3-carbono-thioyl)-2-thioxo-2,3,3a,9a-tetrahydronaphtho[2,3-b]thiophene-4,9-dione (18).

The 3-D conformational shape of N-naphthyl-cyclopenta[d]pyrimidines affects their potency as microtubule targeting agents and their antitumor activity

A series of methoxy naphthyl substituted cyclopenta [d]pyrimidine compounds, 4-10, were designed and synthesized to study the influence of the 3-D conformation on microtubule depolymerizing and antiproliferative activities. NOESY studies with the N,2-dimethyl N-(6′-methoxynaphthyl-1′-amino)-cyclopenta [d]pyrimidin-4-amine (4) showed hindered rotation of the naphthyl ring around the cyclopenta[d]pyrimidine scaffold. In contrast, NOESY studies with N,2-dimethyl-N-(5′-methoxynaphthyl-2′-amino)-cyclopenta[d]pyrimidin-4-amine (5) showed free rotation of the naphthyl ring around the cyclopenta[d]pyrimidine scaffold. The rotational flexibility and conformational dissimilarity between 4 and 5 led to a significant difference in biological activities. Compound 4 is inactive while 5 is the most potent in this series with potent microtubule depolymerizing effects and low nanomolar IC50 values in vitro against a variety of cancer cell lines. The ability of 5 to inhibit tumor growth in vivo was investigated in a U251 glioma xenograft model. The results show that 5 had better antitumor effects than the positive control temozolomide and have identified 5 as a potential preclinical candidate for further studies. The influence of conformation on the micmtubule depolymerizing and antitumor activity forms the basis for the development of conformation-activity relationships for the cyclopenta [d] pyrimidine class of microtubule targeting agents.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 151266-23-8. Formula: C5H4IN5.
