Patient‐derived xenograft models of non‐small cell lung cancer for evaluating targeted drug sensitivity and resistance
Abstract Patient‐derived xenograft (PDX) models are a useful tool in cancer biology research. However, the number of lung cancer PDXs is limited. In the present study, we successfully established ten PDXs, including three adenocarcinoma (AD), six squamous cell carcinoma (SQ) and one large cell carcinoma (LA), from 30 patients with non‐small cell lung cancer (NSCLC) (18 AD, 10 SQ, and 2 LA), mainly in SCID hairless outbred (SHO) mice (Crlj:SHO‐PrkdcscidHrhr). Histology of SQ, advanced clinical stage...

Combined administration of medium‐chain fatty acids and glucose protects against cancer‐associated skeletal muscle atrophy
Abstract Skeletal muscle volume is associated with prognosis of cancer patients. Maintenance of skeletal muscle is an essential issue in cancer treatment. In nutritional intervention, it is important to focus on differences in metabolism between tumor and skeletal muscle. We examined the influence of oral intake of glucose (0%, 10%, 50%) and 2% medium‐chain fatty acid (lauric acid, LAA, C12:0) on tumor growth and skeletal muscle atrophy in mouse peritoneal metastasis models using CT26 mouse colon...

BSP ‐ αvβ3 integrin axis promotes breast cancer metastasis to the bone
Abstract The underlying mechanisms of breast cancer cells metastasizing to distant sites are complex and multi‐factorial. Bone sialoprotein (BSP) and αvβ3 integrin were reported to promote the metastatic progress of breast cancer cells, particularly metastasis to bone. Most theories presume that BSP promote breast cancer metastasis by binding to αvβ3 integrin. Interestingly, we found the αvβ3 integrin decreased in BSP silencing cells (BSPi), which have weak ability to form bone metastases. However,...

Improved survival of CAR‐T and tumor‐specific T cells caused by anti‐PD‐1 scFv‐producing CAR‐T cells
Summary Chimeric antigen receptor‐engineered T (CAR‐T) cell therapy holds a significant promise for the treatment of hematological malignancies, especially for B‐cell leukemia and lymphoma. However, its efficacy against non‐hematological malignancies has been limited due to several biological issues characteristic to the tumor microenvironment of solid tumors. One of the main hurdles would be the heterogeneous nature of tumor‐associated antigens (TAA) expressed in solid tumors. Another hurdle would...

G9a and HDACs are crucial for Snail2‐mediated E‐cadherin repression and metastasis in hepatocellular carcinoma
AbstractFunctional E‐cadherin loss, a hallmark of epithelial‐to‐mesenchymal transition (EMT), is important for metastasis. However, the mechanism of Snail2 in hepatocellular (HCC) EMT and metastasis remains unclear. Here, we showed that Snail2 was upregulated in primary HCC, and significantly increased during TGF‐β‐induced liver cell EMT. Snail2‐overexpressing and knock‐down cell lines have been established to determine its function in EMT in HCC. H3K9 methylation was up‐regulated and H3K4 and H3K56...

Intra‐pulmonary arteriovenous anastomoses and pulmonary gas exchange: evaluation by microspheres, contrast echocardiography and inert gas elimination
Key points Imaging techniques such as contrast echocardiography suggest that anatomic intra‐pulmonary arteriovenous anastomoses (IPAVAs) are present at rest and are recruited to a greater extent in conditions such as exercise. IPAVAs have the potential to act as a shunt, however, gas exchange methods have not demonstrated significant shunt in the normal lung. To evaluate this discrepancy, we compared anatomic shunt with 25‐µm microspheres to contrast echocardiography, and gas exchange shunt measured...

Being mostly non-functional, and accumulating mutations more slowly than mitochondrial sequence, they act like molecular fossils - they preserve information on the ancestral sequences of the mitochondrial DNA. In addition, changes to the Numt sequence since their insertion into the nuclear genome carry information about the nuclear phylogeny. These attributes cannot be reliably exploited if Numt sequence is confused...

Cost-free lifespan extension via optimisation of gene expression in adulthood supports the developmental theory of ageing [NEW RESULTS]
Classic theory upholds that energy trade-offs between reproduction and somatic maintenance underpin the evolution of ageing and lifespan. In contrast, the developmental theory of ageing (DTA) suggests that organismal senescence is caused by dysregulated gene expression in adulthood due to decline in selection gradients with age. The DTA predicts that age-specific optimisation of gene expression can improve survival without fitness costs. Here we investigated consequences for survival, reproduction,...

Region-specific magnetic fields structure sea turtle populations [NEW RESULTS]
Philopatry and long distance migrations are common in the animal kingdom, of which sea turtles are flagship examples. Recent studies have suggested sea turtles use the Earth's magnetic field to navigate across ocean basins to return to their natal area, yet the mechanisms underlying this process remain unknown. If true though, the genetic structure at nesting sites should positively correlate with differences in location-specific magnetic vectors within nesting regions. Here, we confirm this working...

Are rhinoviruses implicated in the pathogenesis of sinusitis and chronic rhinosinusitis exacerbations? A comprehensive review
Background Rhinovirus (RV) infections are the most common cause of viral upper respiratory infections (URIs), and in the majority of persons they are self‐limiting. However, in others, viral URIs can progress to bacterial sinusitis and induce chronic rhinosinusitis (CRS) exacerbations. Methods We conducted a comprehensive Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) review through April 2018 based on MEDLINE, EMBASE, Web of Science–Science Citation Index (SCI),...

Escalation in mucus cystatin 2, pappalysin‐A, and periostin levels over time predict need for recurrent surgery in chronic rhinosinusitis with nasal polyps
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is treated using oral/topical steroids and surgery. Despite maximal medical therapy, some patients remain recalcitrant. Mucus cystatin 2, pappalysin‐A, and periostin can predict the presence of CRSwNP and correlate with disease severity. This study was designed to determine whether prospective sampling of these mucus proteins could predict medical failure and the need for revision surgery. Methods This investigation was an institutional...
