DOI: 10.1099/ijsem.0.005535
Abstract: A Gram-stain-negative, aerobic, orange-coloured, rod-shaped and non-motile bacterial strain, PAMC 29362T, was isolated from an Antarctic lichen, Megaspora verrucosa. Phylogenetic and phylogenomic analyses indicated that strain PAMC 29362T belongs to the genus Polymorphobacter and was… read more here.

DOI: 10.2147/ott.s371042
Abstract: Background Glioma stem cells (GSCs) have been reported to contribute to tumor initiation and relapse, therapy resistance, and intra-tumoral heterogeneity of glioblastoma multiforme. Therefore, inhibiting GSCs presents a critical therapeutic tactic to suppress the aggressiveness… read more here.
