Data from: Preference for mammalian urine is higher in the canopy than on the ground in a tropical rainforest ant community in Yunnan, China
<p>Ants are among the most abundant groups of arthropods, and approximately half of all ant species are associated with forest canopies. The forest canopy environment is distinct from the understory and forest floor, and vertical stratification in environmental conditions shapes species assembly and organismal traits and behaviors across taxa in forest communities. Canopy ants are faced with a more nitrogen-limited environment compared with ground ants because of their reliance on nitrogen-poor plant and insect exudates. Despite prior work suggesting that some ant species consume mammalian urine and use symbiotic bacteria to extract nitrogen, we have little knowledge about the consumption of urine in canopy ants or the relative preference for urine between ground and canopy ants. We conducted an observational field experiment in a lowland tropical rainforest in southern China to test for vertical stratification in ant preference for sugar and urine, setting ground and canopy baited pitfall traps with the use of a canopy crane. We found distinct vertical stratification in the use of urine, with higher richness and abundance in sugar baits on the ground, and a higher abundance in urine baits in the canopy. Furthermore, the composition of captured ants differentiated according to both vertical stratum and bait type. This distinct vertical stratification of niche preference may represent an important case of niche partitioning that contributes to high ant species diversity in tropical rainforests as well as high species turnover between ground and canopy strata. The preference of canopy ants for mammalian urine also highlights the importance of interspecific interactions across highly unrelated animal taxa and emphasizes the need for a holistic understanding of biological networks to effectively conserve threatened tropical forest communities.</p>

Validation of urine p-cresol glucuronide as renal cell carcinoma non-invasive biomarker
<p><strong>Description of the study</strong>: Renal cell carcinoma (RCC) stands among the most lethal urological malignancies. Most RCCs are incidentally diagnosed as initial symptoms are unspecific. Novel, minimally-invasive diagnostic and prognostic methods for RCC are needed, ideally in urine.</p> <p>Using UPLC-Q-ToF MS untargeted metabolomic analysis in urine, we previously revealed p-cresol glucuronide as potential RCC diagnostic marker. Additionally, urine samples one-year post-nephrectomy revealed isobutyryl-L-carnitine and L-proline betaine as potential RCC prognostic markers. Our present aim was to validate these differences in an independent cohort of RCC patients and healthy controls to strengthen their value as non-invasive biomarkers.</p> <p>In an independent cohort of 69 RCC patients and 52 controls we validated an increase in p-cresol glucuronide in urine from patients at diagnosis compared to controls (<em>P</em>=0.0043). It remained increased one-year post-nephrectomy (<em>P</em>=0.0288). The value of p-cresol glucuronide for RCC diagnosis was assessed with ROC curves analysis (AUC=0.66, 95% Confidence Interval 0.56-0.76). The role of isobutyryl-L-carnitine and <a name="_Hlk172707445"></a>L-proline betaine as prognostic markers could not be validated and will require a larger cohort.</p> <p>Our findings confirm the value of p-cresol glucuronide in urine as diagnostic marker for RCC in an independent cohort. This non-invasive method holds promise for enhancing patient care by reducing the need for potentially risky diagnostic procedures. Further metaproteomics-oriented approaches towards the tyrosine oxidation pathway and microbiota metagenomics studies may promote a holistic management of RCC.</p> <p><strong>Description of the data:</strong></p> <p>We provided data in .d format adquired with Agilent.</p> <p> </p> <p> </p>

<p><strong>Supplemental Figure S4.</strong> Nitrogen losses through feces, urine and milk as a percentage of the total N intake through feed (indicated by the red line), for each treatment group (CTRL, MetLys and MetLysHis) in each period (depletion, RP-AA, cross-back). No significant differences nor tendencies were determined between treatment groups within every period by Tukey’s pairwise comparison test (<em>P</em> > 0.10). During the whole experiment all treatment groups received a low protein diet (CTRL). The cows in the MetLys group received rumen-protected (RP) Met (Excential Rumenpass MET, Orffa Additives) and RP-Lys (AjiPro-L, Ajinomoto H&N) during the RP-AA period. The cows in the MetLysHis group received RP-Met, RP-Lys and RP-His (experimental RP-His product, Ajinomoto Co.) during the RP-AA period.</p>

CE-MS was employed to acquire proteomics profiles from 970 patients from two different clinical centers. with the aim to develop a biomarker model to detect Prostate Cancer. </p>
Immunoassay and proteomics dataset: Identification and validation of urine CXCL-9 as a biomarker for diagnosis of acute interstitial nephritis
<p>Background: Acute tubulointerstitial nephritis (AIN) is one of the few causes of acute kidney injury with diagnosis-specific treatment options. However, due to the need to obtain a kidney biopsy for histological confirmation, AIN diagnosis can be delayed, missed, or incorrectly assumed. Here we identify and validate urine CXCL-9, an interferon-γ-induced chemokine involved in lymphocyte chemotaxis, as a diagnostic biomarker for AIN.</p> <p>Methods: In a prospectively-enrolled cohort with pathologist-adjudicated histological diagnoses (<em>discovery cohort</em>), we tested the association of 180 immune proteins measured by an aptamer-based assay with AIN and validated the top protein, CXCL-9, using sandwich immunoassay. We externally validated these findings in 2 cohorts with biopsy-confirmed diagnoses (<em>validation cohorts</em>) and examined mRNA expression differences in kidney tissue from patients with AIN and controls.</p> <p>Results: In aptamer-based assay, urine CXCL-9 was 7.6-fold higher in AIN than controls (<em>P</em>=1.23·10<sup>-5</sup>). Urine CXCL-9 measured by sandwich immunoassay was associated with AIN in the discovery cohort (n=204; 15% AIN) independently of currently available clinical tests for AIN (adjusted odds ratio for highest vs lowest quartile: 6.0; 95% CI: 1.8-20). Similar findings were noted in external validation cohorts, where CXCL-9 had an AUC of 0.94 (0.86-1.00) for AIN diagnosis. <em>CXCL9</em> mRNA expression was 3.9-fold higher in kidney tissue from patients with AIN (n=19) as compared with controls (n=52; P=5.8·10<sup>-6</sup>).</p> <p>Conclusion: We identified CXCL-9 as a biomarker for AIN diagnosis using aptamer-based urine proteomics, confirmed this association using sandwich immunoassays in discovery and validation cohorts, and observed higher expression of this protein in kidney biopsies with AIN. </p>
