Modulation of the IGF1R-MTOR Pathway Attenuates Motor Neuron Toxicity of Human ALS SOD1G93A Astrocytes

The authors showed elevated activation of the MTOR pathway in human-derived astrocytes harboring mutant SOD1, which resulted in inhibition of macroautophagy/autophagy, increased cell proliferation, and enhanced astrocyte reactivity.

Unconventional Secretion of PKCδ Exerts Tumorigenic Function via Stimulation of ERK1/2 Signaling in Liver Cancer

Scientists showed that PKCδ is a secretory protein that regulated cell growth of liver cancer. Full-length PKCδ was secreted to the extracellular space in living liver cancer cells under normal cell culture conditions and in xenograft mouse models.

Insulin Receptor Substrate-1 (IRS-1) Mediates Progesterone Receptor-Driven Stemness and Endocrine Resistance in Oestrogen Receptor+ Breast Cancer

The transcriptomes of primary tumors and metastases in mice harbouring estrogen receptor+ breast cancer patient-derived xenografts were analysed following single-cell RNAseq. In vitro assays were employed to delineate mechanisms of endocrine resistance and stemness.

Enhancer Reprogramming Confers Dependence on Glycolysis and IGF Signaling in KMT2D Mutant Melanoma

The authors identified KMT2D as a potent tumor suppressor in melanoma through an in vivo epigenome-focused pooled RNAi screen and confirmed the finding by using a genetically engineered mouse model based on conditional and melanocyte-specific deletion of KMT2D.

The RNA m6A Reader YTHDF2 Maintains Oncogene Expression and Is a Targetable Dependency in Glioblastoma Stem Cells

Researchers interrogated N6-methyladenosine (m6A) mRNA modifications in glioma stem cells by methyl RNA-immunoprecipitation followed by sequencing and transcriptome analysis, finding transcripts marked by m6A often upregulated compared to normal neural stem cells.
