PlyNJ3: a three-domain endolysin with broad-spectrum anti-streptococcal activity and synergistic efficacy against multidrug-resistant Streptococcus suis

BMC Veterinary Research
Background The global spread of multidrug-resistant (MDR) bacteria prompts the exploration of innovative antimicrobial strategies. Phage lysins—peptidoglycan hydrolases known for species-specific activity and low resistance potential—offer promising ...

Effective Mixed-Type Tissue Crusher and Simultaneous Isolation of RNA, DNA, and Protein from Solid Tissues Using a TRIzol-Based Method

J
One of the major challenges of studying biomarkers in tumor samples is the low quantity and quality of isolated RNA, DNA, and proteins. Additionally, the extraction methods ideally should obtain macromolecules from the same tumor biopsy, allowing better ...

DRUG-RESISTANCE OF BACTERIS

The KITAKANTO Medical Journal, 1963
In the field study many types of drug-resistant E. coli, Shigella and Citrobacter were isolated by this laboratory. And seven types of transmissible drug-resistance factor were obtained; R(TC) R(SM), R(CM. TC), R(SM. SA), R(CM. SM SA), R(TC. SM. SA) and R(CM. TC.SM. SA). The R(CM) factor was segregated from (CM.

Molecular imaging predicts trastuzumab‐deruxtecan (T‐DXd) response in head and neck cancer xenograft models

Molecular Oncology, EarlyView.
Trastuzumab‐deruxtecan, a HER2‐targeting antibody‐drug conjugate, shows promising antitumor activity in head and neck squamous cell carcinoma with low HER2 expression. In vitro and in vivo studies demonstrated dose‐dependent cell death and tumor growth reduction in low HER2‐expressing cell lines, which correlated with drug accumulation measured using a

Genomics‐led approach to drug testing in models of undifferentiated pleomorphic sarcoma

Molecular Oncology, EarlyView.
GA text Genomic data from undifferentiated pleomorphic sarcoma patients and preclinical models were used to inform a targeted drug screen. Selected compounds were tested in 2D and 3D cultures of UPS cell lines. A combination of trametinib and infigratinib was synergistic in the majority of UPS cell lines tested, which was further confirmed in an ex ...

Murine Leukemia Viruses: Objects and Organisms

Advances in Virology, 2011
Murine leukemia viruses (MLVs) are among the simplest retroviruses. Prototypical gammaretroviruses encode only the three polyproteins that will be used in the assembly of progeny virus particles.

Dual activity of PNGM-1 pinpoints the evolutionary origin of subclass B3 metallo-β-lactamases: a molecular and evolutionary study

Emerging Microbes and Infections, 2019
Resistance to β-lactams is one of the most serious problems associated with Gram-negative infections. β-Lactamases are able to hydrolyze β-lactams such as cephalosporins and/or carbapenems.

BMP antagonist CHRDL2 enhances the cancer stem‐cell phenotype and increases chemotherapy resistance in colorectal cancer

Molecular Oncology, EarlyView.
Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

EGFR‐STAT3 activation provides a therapeutic rationale for targeting aggressive ETV1‐positive prostate cancer

Molecular Oncology, EarlyView.
Cotargeting EGFR and STAT3 with Erlotinib and TTI‐101 impairs both 2D and 3D growth of ETV1‐overexpressing prostate cancer cells by disrupting a self‐sustaining ETV1–EGFR positive feedback loop that promotes EGFR and STAT3 expression and phosphorylation (activation).
