Which of your antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for stable selection in mammalian cells?
All of our antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for making multiple stable cell lines. However, kill curves will need to be performed for each combination of antibiotics since sensitivity to a given antibiotic tends to increase when combined with other antibiotics.
How light-sensitive is Puromycin Dihydrochloride?
Puromycin Dihydrochloride is light sensitive on par with the light sensitivity of most basal media like DMEM and RPMI 1640. We would recommend limiting exposure of this product to light as much as possible (i.e,. don't leave on the bench or under hood lights longer than necessary). That said, using a light microscope to observe cells under normal conditions and timeframes will not break down the antibiotic.
Trop2 Promotes Multidrug Resistance by Regulating Notch1 Signaling Pathway in Gastric Cancer Cells.
Authors:Kuai X, Jia L, Yang T, Huang X, Zhao W, Zhang M, Chen Y, Zhu J, Feng Z, Tang Q
Journal:Med Sci Monit
PubMed ID:31964857
'BACKGROUND Chemotherapy is widely used in gastric cancer treatment, but multidrug resistance remains a leading cause of chemotherapy failure. Trop2 is highly expressed in gastric tumor tissues and greatly influences cancer progression. However, little is known about the relationship between Trop2 and drug resistance in gastric cancer.

mTORC2 contributes to the metabolic reprogramming in EGFR tyrosine-kinase inhibitor resistant cells in non-small cell lung cancer.
Authors:Chiang CT, Demetriou AN, Ung N, Choudhury N, Ghaffarian K, Ruderman DL, Mumenthaler SM
Journal:Cancer Lett
PubMed ID:30036610
Non-small cell lung cancer (NSCLC) patients with activating EGFR mutations are often successfully treated with EGFR tyrosine kinase inhibitor (TKI) such as erlotinib; however, treatment resistance inevitably occurs. Given tumor metabolism of glucose and therapeutic response are intimately linked, we explored the metabolic differences between isogenic erlotinib-sensitive and -resistant NSCLC ... More
The Plasmodium falciparum cytoplasmic translation apparatus: a promising therapeutic target not yet exploited by clinically approved anti-malarials.
Authors:Sheridan CM, Garcia VE, Ahyong V, DeRisi JL
Journal:Malar J
PubMed ID:30541569
The continued spectre of resistance to existing anti-malarials necessitates the pursuit of novel targets and mechanisms of action for drug development. One class of promising targets consists of the 80S ribosome and its associated components comprising the parasite translational apparatus. Development of translation-targeting therapeutics requires a greater understanding of protein ... More
Cardiac glycosides decrease influenza virus replication by inhibiting cell protein translational machinery.
Authors:Amarelle L, Katzen J, Shigemura M, Welch LC, Cajigas H, Peteranderl C, Celli D, Herold S, Lecuona E, Sznajder JI
Journal:Am J Physiol Lung Cell Mol Physiol
PubMed ID:30892074
Cardiac glycosides (CGs) are used primarily for cardiac failure and have been reported to have other effects, including inhibition of viral replication. Here we set out to study mechanisms by which CGs as inhibitors of the Na-K-ATPase decrease influenza A virus (IAV) replication in the lungs. We found that CGs ... More
Modulating eIF6 levels unveils the role of translation in ecdysone biosynthesis during Drosophila development.
Authors:Russo A, Gatti G, Alfieri R, Pesce E, Soanes K, Ricciardi S, Mancino M, Cheroni C, Vaccari T, Biffo S, Calamita P
Journal:Dev Biol
PubMed ID:31283922
During development, ribosome biogenesis and translation reach peak activities, due to impetuous cell proliferation. Current models predict that protein synthesis elevation is controlled by transcription factors and signalling pathways. Developmental models addressing translation factors overexpression effects are lacking. Eukaryotic Initiation Factor 6 (eIF6) is necessary for ribosome biogenesis and efficient ... More
