Cytometry A 2018 Dec;93(12):1260-1266

Menarini Silicon Biosystems S.p.A, Bologna, Italy.

Circulating tumor cells (CTCs) are rare cells shed into the bloodstream by invasive tumors and their analysis offers a promising noninvasive tool to predict and monitor therapeutic responses. CTCs can be isolated from patient blood and their characterization at single-cell level can inform on the genomic landscape of a tumor. All CTC enrichment methods bear a burden of contaminating normal cells, which mandate a further step of purification to enable reliable downstream genetic analysis. Read More

Department of Radiation Oncology, Inselspital, Bern University Hospital, University of Bern, 3008, Bern, Switzerland; Department for BioMedical Research, Radiation Oncology, University of Bern, 3008, Bern, Switzerland. Electronic address:

Following nearly two decades of its conception, the phenomenon of oncogene addiction still represents a key concept of how progresses in basic research can translate to unprecedented translational breakthroughs. Coined by Bernard Weinstein, this term refers to the phenomenon by which cancer cells can exhibit dependence on a single oncogenic protein or signaling pathway for sustaining proliferation and survival, despite the wide burden of genetic lesions characterizing their genomic background, revealing thus a promising Achilles' heel of cancer. Importantly, this concept aided the design and clinical implementation of molecularly targeted anticancer therapies, further supporting the paradigm shift witnessed in clinical oncology towards an individual-based, personalized era.

Organoid Modeling of the Tumor Immune Microenvironment.

Cell 2018 Dec;175(7):1972-1988.e16

Department of Medicine, Division of Hematology, Stanford University School of Medicine, Stanford, CA, USA. Electronic address:

In vitro cancer cultures, including three-dimensional organoids, typically contain exclusively neoplastic epithelium but require artificial reconstitution to recapitulate the tumor microenvironment (TME). The co-culture of primary tumor epithelia with endogenous, syngeneic tumor-infiltrating lymphocytes (TILs) as a cohesive unit has been particularly elusive. Here, an air-liquid interface (ALI) method propagated patient-derived organoids (PDOs) from >100 human biopsies or mouse tumors in syngeneic immunocompetent hosts as tumor epithelia with native embedded immune cells (T, B, NK, macrophages).

CARM1 and Paraspeckles Regulate Pre-implantation Mouse Embryo Development.

Cell 2018 Dec;175(7):1902-1916.e13

Department of Physiology, Development and Neuroscience, University of Cambridge, Downing Street, Cambridge CB2 3EG, UK. Electronic address:

Nuclear architecture has never been carefully examined during early mammalian development at the stages leading to establishment of the embryonic and extra-embryonic lineages. Heterogeneous activity of the methyltransferase CARM1 during these stages results in differential methylation of histone H3R26 to modulate establishment of these two lineages. Here we show that CARM1 accumulates in nuclear granules at the 2- to 4-cell stage transition in the mouse embryo, with the majority corresponding to paraspeckles. Read More

Multisensory Logic of Infant-Directed Aggression by Males.

Cell 2018 Dec;175(7):1827-1841.e17

Howard Hughes Medical Institute, Department of Molecular and Cellular Biology, Harvard University, Cambridge, MA 02138, USA. Electronic address:

Newborn mice emit signals that promote parenting from mothers and fathers but trigger aggressive responses from virgin males. Although pup-directed attacks by males require vomeronasal function, the specific infant cues that elicit this behavior are unknown. We developed a behavioral paradigm based on reconstituted pup cues and showed that discrete infant morphological features combined with salivary chemosignals elicit robust male aggression. Read More

Irisin Mediates Effects on Bone and Fat via αV Integrin Receptors.

Cell 2018 Dec;175(7):1756-1768.e17

Department of Cancer Biology, Dana-Farber Cancer Institute, Boston, MA 02115, USA; Department of Cell Biology, Harvard University Medical School, Boston, MA 02115, USA. Electronic address:

Irisin is secreted by muscle, increases with exercise, and mediates certain favorable effects of physical activity. In particular, irisin has been shown to have beneficial effects in adipose tissues, brain, and bone. However, the skeletal response to exercise is less clear, and the receptor for irisin has not been identified. Read More

N-acetylation of Cytidine in mRNA by NAT10 Regulates Stability and Translation.

Cell 2018 Dec;175(7):1725-1727

Cancer Research Center and Wohl Institute for Translational Medicine, Chaim Sheba Medical Center, Tel Hashomer, Israel; Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel. Electronic address:

Arango et al. expand the repertoire of epitranscriptomic modifications by identifying N-acetylcytidine in mRNA catalyzed by the known dual acetyltransferase NAT10. It occurs mainly in the coding sequence, likely in wobble positions of select codons, where it promotes stability and translation, possibly by safeguarding cognate codon-anticodon interaction.

Phase Separation, Protein Disorder, and Enhancer Function.

Authors:
Steven Hahn

Cell 2018 Dec;175(7):1723-1725

Fred Hutchinson Cancer Research Center, Seattle, WA, USA. Electronic address:

New findings suggest that transcription enhancers work by recruitment of a large dynamic network of coactivators and other factors responsible for gene activation. Formation of these condensates is driven by DNA-bound transcription factors, their intrinsically disordered activation domains, and dynamic low-specificity interactions within the complex. Read More

NKG2A, a New Kid on the Immune Checkpoint Block.

Cell 2018 Dec;175(7):1720-1722

MRC Human Immunology Unit, Weatherall Institute of Molecular Medicine, University of Oxford, UK.

One of the major breakthroughs of cancer immunotherapy has come from blocking immune checkpoint molecules on tumor-reactive T cells. Now, two studies examine targeting of a novel immune checkpoint, NKG2A, that can be expressed on both NK cells and on CD8 T cells, either combined with a tumor-targeting antibody or with a tumor-specific vaccine.

miRNA networks modulate human endothelial cell adaptation to cyclic hypoxia.

Cell Signal 2018 Dec 11. Epub 2018 Dec 11.

Department of Biology and Pharmaceutical Botany, Medical University of Gdansk, Gdansk, Poland. Electronic address:

Solid tumor microenvironments are often subjected to various levels of hypoxia. Although regulation of gene expression has been examined extensively, most studies have focused on prolonged hypoxia. The tumor microenvironment, however, experiences waves of hypoxia and reoxygenation that stimulate the expression of pro-angiogenic factors that promote blood vessel formation. Read More
