TL;DR: A model for the alpha-carbon positions in the seven transmembrane helices in the rhodopsin family of G-protein-coupled receptors is presented and suggests which of the residues that are highly conserved in this family of receptors interact with each other.

TL;DR: The developmental relationships between the various ILC lineages that have been identified to date are reviewed and their functions in protective immunity to infection and their pathological roles in allergic and autoimmune diseases are summarized.
Abstract: Innate lymphoid cells (ILCs) are newly identified members of the lymphoid lineage that have emerging roles in mediating immune responses and in regulating tissue homeostasis and inflammation. Here, we review the developmental relationships between the various ILC lineages that have been identified to date and summarize their functions in protective immunity to infection and their pathological roles in allergic and autoimmune diseases.

TL;DR: It is suggested that the 3′ AU-rich sequences act to destabilize the mRNA by directing rapid removal of the mRNA poly(A) tract.
Abstract: The c-fos proto-oncogene provides a good system to study the processes underlying messenger RNA degradation. After growth factor stimulation of susceptible cells, the c-fos transcription rate transiently increases from a low basal level by as much as 50-fold, producing a large amount of exceedingly unstable c-fos mRNA that is rapidly degraded. Here, we investigate the c-fos mRNA degradation process, and find that: (1) ongoing translation of the c-fos mRNA itself is required for its degradation; (2) after synthesis, the mRNA poly(A) tail is rapidly removed, in a translation-dependent manner, leading to accumulation of apparently deadenylated RNA; (3) deletion or replacement of an AU-rich sequence at the mRNA 3' end significantly stabilizes the mRNA; (4) deletion of the 3' AU-rich sequences dramatically slows the poly(A) shortening rate. These results suggest that the 3' AU-rich sequences act to destabilize the mRNA by directing rapid removal of the mRNA poly(A) tract.

TL;DR: It is demonstrated that MALAT1 levels are regulated during normal cell cycle progression, and mechanistic insights on the role of MALat1 in regulating cellular proliferation are provided.
Abstract: The long noncoding MALAT1 RNA is upregulated in cancer tissues and its elevated expression is associated with hyper-proliferation, but the underlying mechanism is poorly understood. We demonstrate that MALAT1 levels are regulated during normal cell cycle progression. Genome-wide transcriptome analyses in normal human diploid fibroblasts reveal that MALAT1 modulates the expression of cell cycle genes and is required for G1/S and mitotic progression. Depletion of MALAT1 leads to activation of p53 and its target genes. The cell cycle defects observed in MALAT1-depleted cells are sensitive to p53 levels, indicating that p53 is a major downstream mediator of MALAT1 activity. Furthermore, MALAT1-depleted cells display reduced expression of B-MYB (Mybl2), an oncogenic transcription factor involved in G2/M progression, due to altered binding of splicing factors on B-MYB pre-mRNA and aberrant alternative splicing. In human cells, MALAT1 promotes cellular proliferation by modulating the expression and/or pre-mRNA processing of cell cycle–regulated transcription factors. These findings provide mechanistic insights on the role of MALAT1 in regulating cellular proliferation.
