CRISPR/Cas9 Mediated Generation and Analysis of N-Terminus Polymorphic Models of beta2-Adrenoreceptor in Isogenic hPSC Derived Cardiomyocytes

Investigators used CRISPR/Cas9 gene editing technology in human (h)PSCs to create a unique suite of four isogenic homozygous variants at amino acid positions 16(G/R) and 27(G/Q), which reside in the N-terminus of the β2AR.

A Multifunctional LNA Oligo-Based Strategy Blocks Androgen Receptor Expression and Transactivation Activity in Prostate Cancer Cells

The Androgen Receptor (AR) plays a critical role in the development of prostate cancer (PCa) through the activation of androgen-induced cellular proliferation genes. Using tailor-made splice switching Locked Nucleic Acid (LNA) oligos, scientists successfully redirected splicing of the AR pre-mRNA and destabilized the transcripts via the introduction of premature stop codons.

A Broad Response to Intracellular Long-Chain Polyphosphate in Human Cells

Polyphosphates (polyPs) are long chains of inorganic phosphates linked by phosphoanhydride bonds. They are found in all kingdoms of life, playing roles in cell growth, infection, and blood coagulation. Scientists demonstrated that internally produced polyP can activate diverse signaling pathways in human cells.

Parallel Ascending Spinal Pathways for Affective Touch and Pain

Investigators showed two populations of projection neurons that expressed the structurally related G-protein-coupled receptors, TACR1 and GPR83 form parallel ascending circuit modules that cooperate to convey thermal, tactile and noxious cutaneous signals from the spinal cord to the lateral parabrachial nucleus of the pons.

Metabolic Regulation by PPARγ Is Required for IL-33-Mediated Activation of ILC2s in Lung and Adipose Tissue

Scientists found that the metabolic sensor peroxisome proliferator-activated receptor gamma was highly expressed in ILC2s of the lung and adipose tissue and increased responsiveness to IL-33.

FoxO Maintains a Genuine Muscle Stem-Cell Quiescent State Until Geriatric Age

Interventions to neutralize Akt and promote FoxO activity drive a primed-to-genuine state conversion, whereas FoxO inactivation deteriorated the genuine state at a young age, causing regenerative failure of muscle, as occurs in geriatric mice.
