Overexpression of HOXA10 promotes the growth and metastasis of nasopharyngeal carcinoma.

Exp Biol Med (Maywood) 2021 Jul 22:15353702211030854. Epub 2021 Jul 22.

Department of Oncology, the Second Affiliated Hospital of Nanchang University, Nanchang 330006, China.

Deregulation of HOX transcription factor family has frequently been observed in multiple human cancers; however, their role in nasopharyngeal carcinoma remains largely unclear. In the present study, we found that HOX gene family is consistently upregulated in nasopharyngeal carcinoma and identified HOXA10 as one of the mostly upregulated HOX genes. Importantly, we show that HOXA10 overexpression is associated with transcriptional activation of multiple oncogenes essential for nasopharyngeal carcinoma carcinogenesis, including S-phase kinase-associated protein 2 (SKP2), calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2), and matrix metalloproteinase 1 (MMP1).

Analyses of lamprey meis genes reveals that conserved inputs from hox, Meis and Pbx proteins control their expression in the hindbrain and neural tube.

Dev Biol 2021 Jul 23. Epub 2021 Jul 23.

Stowers Institute for Medical Research, Kansas City, MO, 64110, USA; Department of Anatomy and Cell Biology, Kansas University Medical Center, Kansas City, KS, 66160, USA. Electronic address:

Meis genes are known to play important roles in the hindbrain and neural crest cells of jawed vertebrates. To explore the roles of Meis genes in head development during evolution of vertebrates, we have identified four meis genes in the Sea Lamprey genome and characterized their patterns of expression and regulation, with a focus on the hindbrain and pharynx. Each of the lamprey meis genes displays temporally and spatially dynamic patterns of expression, some of which are coupled to rhombomeric domains in the developing hindbrain and select pharyngeal arches.

Role of Long Non-Coding RNAs and the Molecular Mechanisms Involved in Insulin Resistance.

Int J Mol Sci 2021 Jul 6;22(14). Epub 2021 Jul 6.

Laboratorio de Epidemiología Clínica y Molecular, Facultad de Ciencias Químico-Biológicas, Universidad Autónoma de Guerrero, Chilpancingo 39087, GRO, Mexico.

Long non-coding RNAs (lncRNAs) are single-stranded RNA biomolecules with a length of >200 nt, and they are currently considered to be master regulators of many pathological processes. Recent publications have shown that lncRNAs play important roles in the pathogenesis and progression of insulin resistance (IR) and glucose homeostasis by regulating inflammatory and lipogenic processes. lncRNAs regulate gene expression by binding to other non-coding RNAs, mRNAs, proteins, and DNA.

Developmental Inhibition of Long Intergenic Non-Coding RNA, , Impairs Dopamine Neuron Differentiation and Maturation.

Int J Mol Sci 2021 Jul 6;22(14). Epub 2021 Jul 6.

Queensland Brain Institute, University of Queensland, Brisbane, QLD 4072, Australia.

The dopaminergic (DA) system is important for a range of brain functions and subcortical DA development precedes many cortical maturational processes. The dysfunction of DA systems has been associated with neuropsychiatric disorders such as schizophrenia, depression, and addiction. DA neuron cell fate is controlled by a complex web of transcriptional factors that dictate DA neuron specification, differentiation, and maturation. Read More

NPM1 Mutational Status Underlines Different Biological Features in Pediatric AML.

Cancers (Basel) 2021 Jul 10;13(14). Epub 2021 Jul 10.

Department of Women's and Children's Health, Haematology-Oncology Clinic and Lab, University of Padova, 35128 Padova, Italy.

Nucleophosmin (NPM1) is a nucleocytoplasmic shuttling protein, predominantly located in the nucleolus, that regulates a multiplicity of different biological processes. NPM1 localization in the cell is finely tuned by specific signal motifs, with two tryptophan residues (Trp) being essential for the nucleolar localization. In acute myeloid leukemia (AML), several NPM1 mutations have been reported, all resulting in cytoplasmic delocalization, but the putative biological and clinical significance of different variants are still debated.

Department of Embryology, St. Petersburg State University, Universitetskaya nab. 7-9, 199034 Saint Petersburg, Russia.

Bilaterian animals operate the clusters of Hox genes through a rich repertoire of diverse mechanisms. In this review, we will summarize and analyze the accumulated data concerning long non-coding RNAs (lncRNAs) that are transcribed from sense (coding) DNA strands of Hox clusters. It was shown that antisense regulatory RNAs control the work of Hox genes in cis and trans, participate in the establishment and maintenance of the epigenetic code of Hox loci, and can even serve as a source of regulatory peptides that switch cellular energetic metabolism.

NOAA Chemical Sciences Laboratory, Boulder, Colorado 80305, United States.

Understanding the efficiency and variability of photochemical ozone (O) production from western wildfire plumes is important to accurately estimate their influence on North American air quality. A set of photochemical measurements were made from the NOAA Twin Otter research aircraft as a part of the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) experiment.

Homeotic change in segment identity derives the human vertebral formula from a chimpanzee-like one.

Am J Phys Anthropol 2021 Jul 6. Epub 2021 Jul 6.

Department of Human Evolutionary Biology, Harvard University, Cambridge, USA.

Objectives: One of the most contentious issues in paleoanthropology is the nature of the last common ancestor of humans and our closest living relatives, chimpanzees and bonobos (panins). The numerical composition of the vertebral column has featured prominently, with multiple models predicting distinct patterns of evolution and contexts from which bipedalism evolved. Here, we study total numbers of vertebrae from a large sample of hominoids to quantify variation in and patterns of regional and total numbers of vertebrae in hominoids. Read More

Int J Mol Sci 2021 Jun 5;22(11). Epub 2021 Jun 5.

Department of Plant Protection, Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, Beijing 100081, China.

The molecular mechanisms of insect resistance to Cry toxins generated from the bacterium (Bt) urgently need to be elucidated to enable the improvement and sustainability of Bt-based products.

Phase separation drives aberrant chromatin looping and cancer development.

Nature 2021 Jul 23;595(7868):591-595. Epub 2021 Jun 23.

Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill School of Medicine, Chapel Hill, NC, USA.

The development of cancer is intimately associated with genetic abnormalities that target proteins with intrinsically disordered regions (IDRs). In human haematological malignancies, recurrent chromosomal translocation of nucleoporin (NUP98 or NUP214) generates an aberrant chimera that invariably retains the nucleoporin IDR-tandemly dispersed repeats of phenylalanine and glycine residues. However, how unstructured IDRs contribute to oncogenesis remains unclear. Read More

Axial elongation of caudalized human organoids mimics aspects of neural tube development.

Development 2021 06 18;148(12). Epub 2021 Jun 18.

Gladstone Institutes, San Francisco, CA 94158, USA.

Axial elongation of the neural tube is crucial during mammalian embryogenesis for anterior-posterior body axis establishment and subsequent spinal cord development, but these processes cannot be interrogated directly in humans as they occur post-implantation. Here, we report an organoid model of neural tube extension derived from human pluripotent stem cell (hPSC) aggregates that have been caudalized with Wnt agonism, enabling them to recapitulate aspects of the morphological and temporal gene expression patterns of neural tube development. Elongating organoids consist largely of neuroepithelial compartments and contain TBXT+SOX2+ neuro-mesodermal progenitors in addition to PAX6+NES+ neural progenitors. Read More
