Figure S4 in Large-scale snake genome analyses provide insights into vertebrate development
Figure S4. Genetic bases of snake limb loss, body elongation, lung asymmetry, and eye structure simplification, related to Figures 3 and 4 (A) Multiple alignments of PTCH1. Fish, mammals, frogs, birds, crocodiles, turtles, lizards, and snakes are indicated in different colors. (B) CPLANE1 multiple alignments. The gene structure is outlined by the black line with yellow blocks representing CDSs. The position span is obtained based on the European glass lizard reference genome. The ''378–381'' and ''473'' show the positions of snake-specific missing amino acids. The ''His472Try'' and ''Gln474Glu'' indicate the two snake-specific amino acid mutations. (C) Relative body mass and relative body length of WT mice and PTCH1-mutated mice with snake deletion. Mean ± SD is shown by error bar. (D) Microstructural characteristics of the proximal shinbone (colored in red) in 1-week-old WT mice and PTCH1-mutated mice with snake deletion. The trabecular bone volume (BV) and bone volume per tissue volume (BV/TV) of WT type and PTCH1-mutated mice. Significantly smaller *p <0.05 (independent Student's t test). Mean ± SD is shown by error bar. (E) Statistics of phalanx relative length (absolute length divided by body length) in WT mice and PTCH1-mutated mice with snake deletion. Mutated mice had significantly shorter fourth forelimb phalanx (n = 8, *p <0.05, independent Student's t test) and third hindlimb phalanx (n = 8, *p <0.05, independent Student's t test). Mean ± SD is shown by error bar. (F) Expressions of genes related to limb development in stage E11.5 forelimb bud (left) and hindlimb (right) of WT mice and PTCH1-mutated mice with snake deletion. (G) The 17-bp deletion of snake ZRS enhancer in our newly sequenced snakes. (H) Expression levels of somite development-related genes (under positive selection) in P. dhumnades (40 days post oviposition). (I) AP3B1 multiple alignments of snakes and outgroup. The gene structure is outlined by the black line with orange sticks representing CDSs and the numbers indicating the position span according to the European glass lizard reference genome. The positions of snake lost amino acids residues are indicated by the interval number ''796–800.''and number "802". (J) Example of differentially expressed genes (DEGs) between embryonic left and right lungs (40 days post oviposition) of P. dhumnades. The significance is indicated as *p <0.05, **p <0.01, or ***p <0.001. Mean ± SD is shown by error bar. (K) The SD-CNE located at ~13 kb downstream of YAP1. The identities (compared with the 31 reptile species ancestor sequence) of the SD-CNE were decreasing along the evolution of snakes. (L) A SSSV inserted to the 5 kb upstream of the TITF1 transcriptional start site. The SSSV was predicted to have one binding site of HOXA5 transcription factor. Heatmap (left) displays the expressions (log10(quantiled FPKMs)) of HOXA5 and TITF1 in lung, liver, heart, and muscle of green anole (Acar), keeled slug snake (Pber), and many-banded krait (Bmul). TITF1 and HOXA5 were highly expressed in the lung of all species but the expressions of TITF1 were significantly higher in the two snakes than in green anole (Student's t test p values: 0.0048 [Pber] and 0.0077 [Bmul]). (M) Snake-specific amino acid residues loss of CC2D2A. The black line layouts the gene structure with blue sticks representing CDSs and the numbers indicating the position span based on the European glass lizard reference genome. The interval number ''41–74'' points out the sites of lost amino acid residues in CC2D2A based on European glass lizard sequence. The lost amino acid residues were indicated in red on 3D structure.

INFLAMeR: a machine learning algorithm based on large-scale perturbation screening identified new lncRNAs regulating differentiation and survival of leukaemia cells
<p><strong>Abstract</strong></p> <p>Long non-coding RNAs (lncRNAs) are a diverse group of transcripts with poorly understood<br> functionality. To address this gap, we developed INFLAMeR, an advanced machine learning<br> model trained on CRISPRi screening data, to predict functional lncRNAs using comprehensive<br> genetic features. We experimentally validated the predictions by assessing their impact on cell<br> proliferation and anticancer drug resistance. Among the selected lncRNAs, 85% showed<br> significant effects upon knockdown, while low-scoring lncRNAs had no discernible impact.<br> Notably, our study elucidated the functional role of SNHG6 in hematopoietic differentiation.<br> INFLAMeR greatly enhances the prediction of functional lncRNAs, providing valuable insights<br> into their regulatory landscape. By integrating INFLAMeR with experimental validation, we can<br> identify and characterize functional lncRNAs in a cell-type-specific manner, contributing to a<br> deeper understanding of their involvement in cellular processes. Our findings revealed insights<br> into lncRNA biology and a framework for improving the identification of functional lncRNAs.</p>

A large-scale serological survey in pets from October 2020 through June 2021 in France shows significantly higher exposure to SARS-CoV-2 in cats
<p>Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can infect many animals, including pets such as dogs and cats. Many studies have documented infection in companion animals by bio-molecular and serological methods. However, only a few have compared seroprevalence in cats and dogs from the general population, and these studies were limited by small sample sizes and collections over short periods. Our goal was to obtain a more accurate evaluation of seroprevalence in companion animals in France and to determine whether cats and dogs differ in their exposure to SARS-CoV-2. For this purpose, we conducted an extensive SARS-CoV-2 serological survey of 2036 cats and 3577 dogs sampled by veterinarians during medical examinations in clinics throughout France. Sampling was carried out from October 2020 through June 2021, a period encompassing the second and third waves of SARS-CoV-2 infections in humans in the country. Using a microsphere immunoassay targeting receptor binding domain and trimeric spike protein, we found 7.1% seroprevalence in pets, in a subset of 308 seropositive samples, 26.3% had neutralizing antibodies. We found that cats were significantly more likely to test positive than dogs, with seropositivity rates of 9.3% and 5.9% in cats and dogs, respectively. Finally, data for both species showed that seroprevalence was lower in older animals and was not associated with the date of sampling or the sex of the animal. Our results show that cats are significantly more sensitive to SARS-CoV-2 than dogs, in line with experimental studies showing that cats are more susceptible than dogs. This study reinforces that pets are commonly infected or exposed to SARS-CoV-2, emphasizing the importance of a One-Health approach to the SARS-CoV-2 pandemic and raising the question of vaccination of companion animals in close contact with humans.</p>
