GTEx analysis for the paper entitled: The histone variant H2A.J is enriched in luminal epithelial gland cells
<p>H2A.J is a poorly studied mammalian-specific variant of histone H2A. We used immunohistochemistry to study its localization in various human and mouse tissues. H2A.J showed cell-type specific expression with a striking enrichment in luminal epithelial cells of multiple glands including those of breast, prostate, pancreas, thyroid, stomach, and salivary glands. H2A.J was also highly expressed in many carcinoma cell lines and in particular, those derived from luminal breast and prostate cancer. H2A.J thus appears to be a novel marker for luminal epithelial cancers. Knocking-out the H2AFJ gene in T47D luminal breast cancer cells reduced the expression of several estrogen-responsive genes which may explain its putative tumorigenic role in luminal-B breast cancer.</p>

Datasets for Ash et al. (2024): Testing the Breakdown of the Asteroseismic Scaling Relations in Luminous Red Giants
<p>Datasets used for the high-alpha sequence and cluster analysis in Ash et al. (2024) which explores the efficacy of the asteroseismic scaling relations with a focus on the luminous giant regime. These datasets are a subset of the APOKASC3 dataset, which is publiclly available (Pinsonneault et al. (2024)). The data selection methods to genrate these data subsets are available in Ash et al. (2024). The high-alpha sequence and open cluster datasets are used to compare seismic masses computed with various methods to seismic-independent masses. <a href="https://zenodo.org/api/records/14008022/draft/files/NGC6791_APO_giants+rc_GaiaDR3_membership.txt/content" target="_blank" rel="noopener noreferrer">NGC6791_APO_giants+rc_GaiaDR3_membership.txt</a> and <a href="https://zenodo.org/api/records/14008022/draft/files/NGC6819_APO_giants+rc_GaiaDR3_membership.txt/content" target="_blank" rel="noopener noreferrer">NGC6819_APO_giants+rc_GaiaDR3_membership.txt</a> contains asteroseismic data for red clump and red giant branch stars in the open clusters NGC6791 and NGC6819.

Luminous Salar de Uyuni
<p>Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.</p> <p> </p> <p>This black and white image taken in February 2017 in Uyuni Salt Flat of southwest Bolivia, the biggest salt flat in the world, shows one of the most recognisable constellations, Orion the hunter, and the open star cluster of the Hyades directly above the clouds at the horizon. Various cultures have different stories associated with Orion. The Aymara in this area of the world (Bolivia and Northern Chile) consider Orion’s Belt to be a Sky Bridge (chacka cilitu) or a Stairway made out of dough. This stairway is rather obvious in this picture. It appears as if the stars in the sky are scattered like grains of salt on the ground — an amazing composition.</p> <p>For the Aymara, who were Christianised by the Spanish conquistadores, Orion and the Stairway are connected to the November festivals of the dead ancestors and the souls. In contrast to the original Christian culture, for these people in the southern hemisphere these festivals mark the beginning of summer, not the beginning of winter. While in the north, the “ghosts” of the ancestors are represented by the foggy weather in November, the Aymara greet the ancestors with flowers. This photograph in the dry salt flat, in contrast, seems to show the unlivable loneliness where the photographer meets the souls of the deceased.</p> <p>The Yolnu people of Arnhem Land in Australia’s Northern Territory have a rich culturally significant story associated with Orion that carries a lesson. It tells of the three brothers of the Kingfish clan and their canoe Djulpan. Owing to their lack of patience, the brothers ate the sacred Kingfish, angering the Sun woman Walu who created a waterspout that sent them into the sky. Looking at the constellation Orion, the three stars in Orion’s belt represent the three brothers, Orion’s sword is the fishing line, and the two dimmer stars Bellatrix and Saiph form the two ends of the canoe Djulpan.</p> <p>Credit: Ziyi Stephanie Ye/IAU OAE (<a href="https://creativecommons.org/licenses/by/4.0/legalcode">CC BY 4.0</a>)</p>

Evolution of Pelage Luminance in squirrels (Sciuridae)
<p>Sciurids have one of the greatest diversities of color patterns and hues among mammalian families, but whether these color patterns conform to Gloger's Rule has not been investigated. Gloger's rule is the ecogeographic trend that describes the tendency of animals' pelage to be darker in warmer and wetter environments. Several mechanisms have been proposed explain this trend that relate to various environmental variables. However, these variables frequently correlate with each other which can cause increased Type I error rates in conventional analyses with a single dependent variable. Here we use a new phylogenetic comparative method that implements path analysis to produce a hypothesized series of cause and effect relationships between predictor variables to form a path model. This multi-regression approach allows for the simultaneous exploration of the effects of numerous predictor variables. Our path analysis results using 137 Sciurid species show that squirrel pelage luminance conforms to Gloger's rule and that there is a significant evolutionary relationship between precipitation and pelage luminance. Also significant were that other commonly found variables (humidity, temperature, and vegetation cover) did not have strong relationships with pelage luminance. Our findings demonstrate that utility of path analysis in phylogenetic comparative studies in studying a trait influenced by several covarying variables.</p>

DC-SIGN expression on myeloid population in Luminal Breast Cancer
<p>DC-SIGN expression by the different populations of DC and macrophages found in breast tumor samples using flow cytometry. As previously described (doi:10.1038/s41590-018-0145-8.), we identified four major DC populations: CD11c − CD123+ plasmacytoid pre-DCs, CD11c+BDCA1+ CD14− DCs, CD11c+ BDCA1− CD14− DCs, and CD11c+ BDCA1+ CD14+ inflammatory DCs. Staining was performed using the following antibodies: anti-CD45 APC-Cy7 (BD), anti-CD14 Qdot 605 (Thermo), anti-CD3 Alexa700 (Biolegend), anti-CD 19 Alexa700 (Biolegend), anti-CD56 Alexa700 (Biolegend), 400 anti-HLA-DR BV711 (Biolegend), anti-CD11c PC5 (Beckman Coulter), anti-BDCA-1 PE (BD), anti-CD123 PCy7 (BD) and anti-C-SIGN FITC (BD). Cells were analyzed by a LSRFORTESSA X-20 instrument (BD Biosciences). The most prominent intratumoral myeloid cell population, however, was shown to be represented by macrophages, defined as CD11c+ BDCA1−CD14+ cells. We analyzed DC-SIGN expression on the surface of these populations by flow cytometry. DC-SIGN was only expressed on the membrane of macrophages from tumoral as well as juxtatumoral tissues, but not on the DC populations analyzed. These results are represented in Figure 4 from the publication "Aberrant fucosylation enables breast cancer clusterin to interact with dendritic cell-specific ICAM-grabbing non-integrin (DC-SIGN)". </p> <p> </p>

Transcriptome analysis of T47D cells and H2A.J-KO derivatives for the paper entitled: The histone variant H2A.J is enriched in luminal epithelial gland cells
<p>H2A.J is a poorly studied mammalian-specific variant of histone H2A. We used immunohistochemistry to study its localization in various human and mouse tissues. H2A.J showed cell-type specific expression with a striking enrichment in luminal epithelial cells of multiple glands including those of breast, prostate, pancreas, thyroid, stomach, and salivary glands. H2A.J was also highly expressed in many carcinoma cell lines and in particular, those derived from luminal breast and prostate cancer. H2A.J thus appears to be a novel marker for luminal epithelial cancers. Knocking-out the H2AFJ gene in T47D luminal breast cancer cells reduced the expression of several estrogen-responsive genes which may explain its putative tumorigenic role in luminal-B breast cancer.</p>
