This study showed that long interspersed element-1 (LINE-1) ORF2p expression is almost undetectable in human cancers. LINE-1 is the major driver of mobile DNA activity in humans. When expressed, LINE-1 loci produce bicistronic transcripts encoding two proteins essential for retrotransposition, ORF1p and ORF2p. ORF2p expression is not well characterized in human tissues and cell lines. For the study,...

Long interspersed element-1 (LINE-1) is an autonomous retroelement that utilizes copy and paste mechanism to propagate themselves throughout the genome through a process called retrotransposition. The LINE-1 bicistronic mRNA codes for two proteins, ORF1p and ORF2. While LINE-1 transcription is usually repressed in most healthy somatic cells, ORF1p expression has been observed in tumors, including prostate...

Brain metastasis is the most common intracranial malignancy in adults, which is often fatal. Studies have shown that brain metastases depend on cooperative cellular interactions between tumor cells and specialized cells within the central nervous system (CNS). Metabolic constraints imposed by the serine and glycine limited brain environment restrict metastatic tumor growth. This study showed that 3-phosphoglycerate...

This study showed that basal-like breast cancer (BLBC) is sensitive to suppression of iron-sulfur cluster (ISC) biosynthesis and identified DNA polymerase epsilon (POLE) as an ISC-containing protein that underlies this phenotype. This dataset includes RNA sequencing data and data underlying figures. The publication also contains supplementary data, which includes data for short hairpin RNA (shRNA)...

This study performed loss-of-function screens in a transformed breast cell line using a metabolism-restricted short hairpin RNA (shRNA) library to understand differences in metabolic pathway requirements between in vitro model systems and in vivo tumors. They found that cancer cells depend on high levels of the iron–sulfur cluster biosynthetic enzyme NFS1. This dataset includes supplementary data tied...

This study performed a differential transcriptomic and metabolomic analysis of benign proliferative and transformed liver. They used partial hepatectomy-induced liver regeneration and diethylnitrosamine (DEN) induced carcinogenesis to identify and analyze alterations specific to multiple regenerative and transformed tissue states. This dataset contains supplementary data tied to the publication. The...

CD8+ T cell accumulation in tumors is essential for effective immunotherapy. However, the mechanisms of lymphocyte transit are still unclear. This study examined lymphatic vessel-mediated effector CD8+ T cell exit limits the accumulation of a broad repertoire of functional CD8+ T cells that improve tumor control in combination with immune checkpoint blockade. They showed that tumor-associated lymphatic...

Although targeted cancer therapies have been successful, their efficacies are limited by the development of resistance driven by clonal evolution within tumors. This study developed a single-cell barcoding approach to comprehensively trace clonal dynamics and capture live lineage-coupled resistant cells for in-depth multi-omics analysis and functional exploration. They showed that heterogeneous clones,...

SHP2 plays critical roles in normal cell signaling and SHP2 inhibitors alone and in various combinations are being tested in multiple tumors with overactivation of the RAS/ERK pathway. This study showed that inhibiting the SHP2/RAS/ERK pathway triggers upregulation of CXCR2 ligands. In this study, C57BL/6J mice were used as the orthotopic allograft lung cancer model. They injected KP cells into the...

This study developed a series of synthetic binding proteins called monobodies that are selective to KRAS(G12D). KRAS(G12D) is a common mutation associated with deadly cancers, such as pancreatic and colorectal cancers. Although recent discoveries have revealed that KRAS(G12D) is no longer undruggable, there are still few direct inhibitors selective to KRAS(G12D). The dataset contains structural coordinates...
