USP11 facilitates colorectal cancer proliferation and metastasis by regulating IGF2BP3 stability.

The abnormal expression of ubiquitin-specific protease 11 (USP11) is thought to be related to tumor development and progression; however, few studies have reported the biological function and clinical importance of USP11 in colorectal cancer (CRC). Therefore, it is necessary to further explore the role of USP11 in CRC. Immunohistochemical staining was used to explore the association between prognosis and USP11 expression in CRC.

Clonal spread of macrolide-resistant Mycoplasma pneumoniae sequence type-3 and type-17 with recombination on non-P1 adhesin among children in Taiwan.

Objectives: Mycoplasma pneumoniae is currently the most commonly detected bacterial cause of childhood community-acquired pneumonia in several countries. Of note, clonal expansion of macrolide-resistant ST3 occurred in Japan and South Korea. An alarming surge in macrolide resistance complicates the treatment of pneumonia.

Aberrant USP11 expression regulates NF90 to promote proliferation and metastasis in hepatocellular carcinoma.

Growing evidence indicates that deubiquitinase ubiquitin-specific protease 11 (USP11) plays an important role in cellular function by regulating the stability of its substrates. USP11 is dysregulated in many types of cancer and involved in tumor development and progression. We previously showed that USP11 was upregulated in hepatocellular carcinoma (HCC) and promoted HCC cell invasion and metastasis potency.

Genomic Insight into the Spread of Meropenem-Resistant Streptococcus pneumoniae Spain-ST81, Taiwan.

Incidence of invasive pneumococcal disease caused by antimicrobial-resistant Streptococcus pneumoniae types not included in pneumococcal conjugate vaccines has increased, including a penicillin- and meropenem-resistant serotype 15A-ST63 clone in Japan. During 2013-2017, we collected 206 invasive pneumococcal isolates in Taiwan for penicillin and meropenem susceptibility testing. We found serotypes 15B/C-ST83 and 15A-ST63 were the most prevalent penicillin- and meropenem-resistant clones.

Recurrent and metastatic extragastrointestinal stromal tumors of the mesentery with C-KIT and PDGFRA mutations: a case report.

EGISTs originating outside the gastrointestinal tract share some similarities with the GISTs regarding their immunohistochemical features including the positive expression of CD117 and CD34. The majority of EGISTs carry activating mutations of the C-KIT or PDGFRA genes. However, there is no precedent in the literature where the two mutations occur in one case of EGISTs to date.

Heat-treated rapeseed was supplemented to indoor fed yaks in winter to test the effect on dry matter intake (DMI), body mass change, and meat quality. Sixteen 3-year-old yak steers (124 ± 15.3 kg) were divided randomly into two groups and were offered either heat-treated rapeseed (HTR) or rapeseed meal (CONT).

Prophage Excision in Serotype 19A ST320 Promote Colonization: Insight Into Its Evolution From the Ancestral Clone Taiwan 19F-14 (ST236).

19A ST320, a multidrug-resistant strain with high disease severity that notoriously spread before the use of expanded pneumococcal conjugate vaccines, was derived from a capsular switching event between an international strain Taiwan 19F-14 (ST236) and a serotype 19A strain. However, the molecular mechanisms underlying the adaptive evolution of 19F ST236 to 19A ST320 are unknown. In this study, we compared 19A ST320 to its ancestral clone, 19F ST236, in terms of adherence to respiratory epithelial cells, whole transcriptome, and ability to colonize a young mouse model.
