Organellar Contacts of Milk Lipid Droplets.

Contact (Thousand Oaks (Ventura County, Calif.))

Monks J, Ladinsky MS, McManaman JL.
PMID: 32232194
Contact (Thousand Oaks). 2020 Jan-Dec;3. doi: 10.1177/2515256419897226. Epub 2020 Jan 23.

Milk-secreting epithelial cells of the mammary gland are functionally specialized for the synthesis and secretion of large quantities of neutral lipids, a major macronutrient in milk from most mammals. Milk lipid synthesis and secretion are hormonally regulated and secretion...

Xanthine-derived metabolites enhance chlorophyll degradation in cotyledons and seedling growth during nitrogen deficient condition in .

Plant signaling & behavior

Yi SY, Lee M, Jeevan Rameneni J, Lu L, Kaur C, Lim YP.
PMID: 33955825
Plant Signal Behav. 2021 Jun 03;16(6):1913309. doi: 10.1080/15592324.2021.1913309. Epub 2021 May 06.

Nitrogen (N) deficiency is a main environmental factor that induces early senescence. Cotyledons provide an important N source during germination and early seedling development. In this study, we observed that N deficient condition enhanced gene expression involved in purine...

Combined Methylome and Transcriptome Analyses Reveals Potential Therapeutic Targets for EGFR Wild Type Lung Cancers with Low PD-L1 Expression.

Cancers

Hu W, Wang G, Yarmus LB, Wan Y.
PMID: 32899191
Cancers (Basel). 2020 Sep 03;12(9). doi: 10.3390/cancers12092496.

Immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 have demonstrated remarkable treatment efficacy in advanced non-small cell lung cancer (NSCLC). However, low expression of programmed death-ligand 1 (PD-L1), epidermal growth factor receptor (EGFR) wild-type NSCLCs are refractory, and only few therapeutic...

Inorganic nitrate attenuates cardiac dysfunction: roles for xanthine oxidoreductase and nitric oxide.

British journal of pharmacology

Gee LC, Massimo G, Lau C, Primus C, Fernandes D, Chen J, Rathod KS, Hamers AJP, Filomena F, Nuredini G, Ibrahim AS, Khambata RS, Gupta AK, Moon JC, Kapil V, Ahluwalia A.
PMID: 34309015
Br J Pharmacol. 2021 Jul 26; doi: 10.1111/bph.15636. Epub 2021 Jul 26.

BACKGROUND AND PURPOSE: NO is a vasodilator and independent modulator of cardiac remodelling. Commonly, in cardiac disease (e.g., heart failure), endothelial dysfunction (synonymous with NO deficiency) has been implicated in increased BP, cardiac hypertrophy and fibrosis. Currently, no effective...

Distribution of the Mo-enzymes aldehyde oxidase, xanthine dehydrogenase and nitrate reductase in maize (Zea mays L.) nodal roots as affected by nitrogen and salinity.

Plant science : an international journal of experimental plant biology

Katalin Barabás N, Omarov RT, Erdei L, Herman Lips S.
PMID: 10773339
Plant Sci. 2000 Jun 12;155(1):49-58. doi: 10.1016/s0168-9452(00)00199-0.

The distribution of the Mo-enzymes aldehyde oxidase (AO; EC 1.2.3.1) xanthine dehydrogenase (XDH; EC 1.2.1.37) and nitrate reductase (NAD(P)H NR; EC 1.6.6.1-2) was studied along the longitudinal and transversal axes of maize (Zea mays L. cv. Jubily) nodal roots...

Enzymatic analysis of uricotelic protein catabolism in the mosquito Aedes aegypti.

Journal of insect physiology

von Dungern P, Briegel H.
PMID: 11033169
J Insect Physiol. 2001 Jan 01;47(1):73-82. doi: 10.1016/s0022-1910(00)00095-0.

Excess protein ingested by blood meals of mosquitoes is catabolized by a uricotelic pathway. We have established enzyme activity profiles for xanthine dehydrogenase (XDH), the enzyme that catalyzes uric acid synthesis, and related it to intestinal proteolytic activities in...

Purified horse milk exosomes contain an unpredictable small number of major proteins.

Biochimie open

Sedykh SE, Purvinish LV, Monogarov AS, Burkova EE, Grigor'eva AE, Bulgakov DV, Dmitrenok PS, Vlassov VV, Ryabchikova EI, Nevinsky GA.
PMID: 29450143
Biochim Open. 2017 Mar 01;4:61-72. doi: 10.1016/j.biopen.2017.02.004. eCollection 2017 Jun.

Exosomes are 40-100 nm nanovesicles containing RNA and different proteins. Exosomes containing proteins, lipids, mRNAs, and microRNAs are important in intracellular communication and immune function. Exosomes from different sources are usually obtained by combination of centrifugation and ultracentrifugation and...

A de novo transcriptome of the Malpighian tubules in non-blood-fed and blood-fed Asian tiger mosquitoes Aedes albopictus: insights into diuresis, detoxification, and blood meal processing.

PeerJ

Esquivel CJ, Cassone BJ, Piermarini PM.
PMID: 26989622
PeerJ. 2016 Mar 10;4:e1784. doi: 10.7717/peerj.1784. eCollection 2016.

Background. In adult female mosquitoes, the renal (Malpighian) tubules play an important role in the post-prandial diuresis, which removes excess ions and water from the hemolymph of mosquitoes following a blood meal. After the post-prandial diuresis, the roles that...

Nitrate reductase is not accumulated in chloroplast-ribosome-deficient mutants of higher plants.

Planta

Borner T, Mendel RR, Schiemann J.
PMID: 24232551
Planta. 1986 Oct;169(2):202-7. doi: 10.1007/BF00392315.

The activities of nitrite reductase (EC 1.7.7.1) are 60-70% of wild-type activity in pigment-deficient leaves of the chloroplast-ribosomedeficient mutants 'albostrians' (Hordeum vulgare) and 'iojap' (Zea mays). The activity and apoprotein of nitrate reductase (EC 1.6.6.1.) are lacking in the...

Isolation of biochemical mutants using haploid mesophyll protosplasts of Hyoscyamus muticus : IV. Biochemical characterisation of nitrate non-utilizing clones.

Fankhauser H, Bucher F, King PJ.
PMID: 24258668
Planta. 1984 Apr;160(5):415-21. doi: 10.1007/BF00429757.

Four nitrate non-utilizing clones of Hyoscyamus muticus, obtained by a total isolation method, possess all the known characteristics of cnx-type nitrate-reductase-deficient variants: 1) strict dependence on a reduced nitrogen source such as a mixture of amino acids; 2) chlorate...

Xanthine dehydrogenase/xanthine oxidase and oxidative stress.

Age

Chung HY, Baek BS, Song SH, Kim MS, Huh JI, Shim KH, Kim KW, Lee KH.
PMID: 23604305
Age (Omaha). 1997 Jul;20(3):127-40. doi: 10.1007/s11357-997-0012-2.

Xanthine dehydrogenase (XDH) and xanthine oxidase (XOD) are single-gene products that exist in separate but interconvertible forms. XOD utilizes hypoxanthine or xanthine as a substrate and O2 as a cofactor to produce superoxide (·O2 (-)) and uric acid. XDH...

Kinetics of the inhibition of xanthine dehydrogenase and of the reversible and irreversible forms of xanthine oxidase by silibinin and bendazac.

Environmental toxicology and pharmacology

Silva MP, Mira L, Lima J, Manso CF.
PMID: 21781693
Environ Toxicol Pharmacol. 1996 Jul 15;1(4):279-84. doi: 10.1016/1382-6689(96)00021-X.

Xanthine oxidase exists in vivo predominantly as a NAD(+)-dependent dehydrogenase form (xanthine dehydrogenase) which can be transformed into oxygen-dependent oxidase forms as a result of sulfhydryl oxidation (reversible xanthine oxidase) or proteolysis (irreversible xanthine oxidase). Xanthine oxidase has been...
