Interspecific variation and genetic relationship among Colombian Lippia sp. based on small ribosomal subunit gene sequence analysis

Six Lippia sp. were subjected to sequence analysis of the small ribosomal subunit (SRS) or 18S rDNA gene (ca. 1530 bp in length) for studying their genetic relationship. A total of nine nucleotide differences distinguished the species-specific SRS haplotypes of L. alba, L. americ...

Lippia origanoides extract induces cell cycle arrest and apoptosis and suppresses NF-?B signaling in triple-negative breast cancer cells.

Treatments targeting hormone receptors typically fail to provide a positive clinical outcome against triple-negative breast cancers (TNBC), which lack expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (Her2/neu). Towards...
