    Over 94 million domestic cats are susceptible to cancers and other common and rare diseases. While cancer treatment in cats increasingly mirrors that available in humans, treatment failures are more frequent. There are no FDA or USDA approved cancer drugs for cats and a paucity of cancer treatments beyond surgery, radiotherapy, and cytotoxic chemotherapy indicate an urgent need to define the molecular properties of aggressive feline cancers including common cancers such as soft tissue sarcoma, mammary carcinoma, lymphoma, and feline oral squamous cell carcinoma. Whole exome sequencing (WES) is a proven strategy to study these disease-causing variants in humans and other organisms. To examine the effectiveness of WES in the study of feline cancer and Mendelian diseases, whole exome sequencing was conducted on 41 cats with known and unknown genetic diseases and traits, of which ten cats had matching whole genome sequence (WGS) data available, used to validate WES performance. Within the 41 cats, we identified 31 previously known causal variants and discovered new gene candidate variants, including novel missense variance for polycystic kidney disease and atrichia in the Peterbald cat. The WES data was sufficient to identify novel gene candidate alleles for diseases and traits in a feline model. Feline oral squamous cell carcinoma (FOSCC) is a cancer of the squamous cell lining in the oral cavity and represents up to 80 percent of all oral cancers in cats, with a low one-year survival rate of <10 percent. The cancer pathology associated with feline oral squamous cell carcinoma is similar to human head and neck squamous cell carcinoma (HNSCC), which accounts for 90 percent of oral cancers in humans. FOSCC may present as a potential model to study HNSCC due to spontaneous formation, similar genetic landscape, pathology, and survival rates. We have generated single nucleotide variant calls using GATK-Mutect2 on six cats with FOSCC and have fully annotated and identified driver genes in common with HNSCC. Due to low sample size, a larger cohort is needed to draw stronger association of disease-causing traits. Our results show some overlap in the genetic landscape of both cancers, with five samples have mutations in p53, a common mutation in HNSCC, and two samples having four genes in common with HNSCC each. Several samples with mutations in p53 and mutations in genes implicated in HNSCC suggests that the domestic cat could be a viable model for HNSCC.Includes bibliographical references

    Genetic variants associated with subjective well-being, depressive symptoms, and neuroticism identified through genome-wide analyses

    Very few genetic variants have been associated with depression and neuroticism, likely because of limitations on sample size in previous studies. Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotypes: subjective well-being (n = 298,420), depressive symptoms (n = 161,460), and neuroticism (n = 170,911). We identify 3 variants associated with subjective well-being, 2 variants associated with depressive symptoms, and 11 variants associated with neuroticism, including 2 inversion polymorphisms. The two loci associated with depressive symptoms replicate in an independent depression sample. Joint analyses that exploit the high genetic correlations between the phenotypes (|ρ^| ≈ 0.8) strengthen the overall credibility of the findings and allow us to identify additional variants. Across our phenotypes, loci regulating expression in central nervous system and adrenal or pancreas tissues are strongly enriched for association.</p

This species was misidentified as &lt;i&gt;J. pulla&lt;/i&gt; Young, 1977 by Carvalho &lt;i&gt;et al.&lt;/i&gt; (2015). However, the forewing of &lt;i&gt;J. pulla&lt;/i&gt; has an &ldquo;anteapical transparent angular spot extending from costal margin into outer anteapical cell&rdquo; (Young 1977: p. 464; see digital image in Wilson &lt;i&gt;et al.&lt;/i&gt; 2009) that is not present in &lt;i&gt;J. nigra&lt;/i&gt;. Furthermore, the stalk of the paraphyses is much shorter and broader in &lt;i&gt;J. pulla&lt;/i&gt;, &lt;i&gt;i.e.&lt;/i&gt;, rami longer than stalk (Young 1977: fig. 378h), than in the new species (Fig. 6). &lt;i&gt;Juliaca pulla&lt;/i&gt; was originally described from Panama and is also known from Nicaragua, Costa Rica, and Colombia (see McKamey 2007 and Wilson &lt;i&gt;et al.&lt;/i&gt; 2009).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Etymology.&lt;/b&gt; The new species name, &lt;i&gt;nigra&lt;/i&gt;, refers to the dark brown to black color of the dorsum, without spots or stripes (Fig. 1).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Known distribution.&lt;/b&gt; Southeastern Brazil (State of Esp&iacute;rito Santo).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Material examined.&lt;/b&gt; Brazil, State of Esp&iacute;rito Santo.

The external morphology and color features of our specimens agree with the original description of Jacobi (1905). This colorful and variable species, whose (sometimes interrupted) stripes or spots may be yellow, greenish-yellow, green or bluish-white, can be distinguished by the following features (Figs. 14, 20, 28&ndash;30): (1) crown with transverse stripe extending laterally over antennal ledges, or with pair of lateral spots; (2) pronotum with posterior transverse stripe (sometimes covering most of disk, rarely reduced to a few spots) extending over lateral pronotal lobes; (3) forewing with two transcommissural stripes, a curved preapical stripe, and a vitreous area located at costal margin between distal transcommissural stripe and preapical curved stripe. In addition to the aforementioned color variation, the stripes (crown, pronotum, and forewing) also vary from narrow to broad (Figs. 14, 20, 28&ndash;30; see also images in Wilson &lt;i&gt;et al.&lt;/i&gt; 2009, a site that shows intraspecific color variation in specimens from Chanchamayo, Jun&iacute;n, Peru).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Known distribution.&lt;/b&gt; Ecuador, Peru (Jun&iacute;n, Cusco, Madre de Dios), and Bolivia (La Paz) (Jacobi 1905, Young 1977, McKamey 2007, Wilson &lt;i&gt;et al.&lt;/i&gt; 2009).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Material examined.&lt;/b&gt; Peru, departments of Cusco and Madre de Dios.

This species, which was not treated by Young (1977) in his Cicadellini monograph (McKamey 2007), can be distinguished by the following features: (1) crown with anterior half yellow (Figs. 31, 45); (2) pronotum with broad transverse yellow stripe (Figs. 31, 45); (3) forewing with two large transcommissural yellow spots, first one on basal half of clavus (continuous with apex of scutellum) and second one on distal portion of clavus and extending over corium (Fig. 45); (4) style with apical portion sickleshaped (Fig. 34); (5) aedeagus strongly curved dorsally, with dorsal margin convex and ventral margin concave (Fig. 35); (6) paraphyses with base of rami bearing pair of projections directed anteriorly; rami very slender (Fig. 36). The external features, color pattern, and male terminalia indicate that &lt;i&gt;Juliaca&lt;/i&gt; is the correct generic assignment.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Known distribution.&lt;/b&gt; Southeastern Brazil (states of Minas Gerais and Rio de Janeiro).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Material examined.&lt;/b&gt; Brazil, states of Minas Gerais and Rio de Janeiro, Mantiqueira mountain range (Atlantic Forest).

    Feline oral squamous cell carcinoma (FOSCC) is a cancer of the squamous cell lining in the oral cavity and represents up to 80% of all oral cancers in cats, with a poor prognosis. We have used whole exome sequencing (WES) and RNA sequencing of the tumor to discover somatic mutations and gene expression changes that may be associated with FOSCC occurrence. FOSCC offers a potential comparative model to study human head and neck squamous cell carcinoma (HNSCC) due to its similar spontaneous formation, and morphological and histological features. In this first study using WES to identify somatic mutations in feline cancer, we have identified tumor-associated gene mutations in six cats with FOSCC and found some overlap with identified recurrently mutated genes observed in HNSCC. Four samples each had mutations in TP53, a common mutation in all cancers, but each was unique. Mutations in other cellular growth control genes were also found such as KAT2B and ARID1A. Enrichment analysis of FOSCC gene expression profiles suggests a molecular similarity to human OSCC as well, including alterations in epithelial to mesenchymal transition and IL6/JAK/STAT pathways. In this preliminary study, we present exome and transcriptome results that further our understanding of FOSCC
