Phylogeny and toxicological assessments of two Porthidium lansbergii lansbergii morphotypes from the caribbean region of Colombia.

Toxicon, 2019
After a snakebite accident, species identification is of vital importance. However, the existence of intraspecific differences in the body coloration patterns of venomous snakes can generate confusion and delay a convenient and effective treatment.

A novel pentameric phospholipase A2 myotoxin (PophPLA2) from the venom of the pit viper Porthidium ophryomegas.

International Journal of Biological Macromolecules, 2018
The first toxin isolated from the venomous pit viper Porthidium ophryomegas is a basic pentameric phospholipase A2 (PophPLA2). Elucidation of its amino acid sequence showed that it belongs to the group IIA of secreted PLA2s, with the presence of all 14 ...

Integration and modular patterns shaping the morphological evolution in Neotropical hognose pitvipers Porthidium

Current Zoology
The evolutionary mechanisms driving morphological diversification remain poorly understood for many organismal lineages. We investigated the morphological evolution of the hognose pitviper genus Porthidium (Viperidae: Crotalinae). Using a comprehensive

Cytotoxic and anti-metastatic effects of Pllans-II from Porthidium lansbergii lansbergii venom against prostate cancer cells.

Biochemical and Biophysical Research Communications - BBRC
Prostate cancer remains a major health challenge due to therapeutic resistance and the adverse effects of conventional treatments. Snake venom phospholipases A2 have emerged as promising bioactive molecules with selective anti-cancer properties.

Lansbermin-I, a disintegrin from Porthidium lansbergii lansbergii venom as a potential anticancer prototype: In vitro and in silico effects on cervical cancer cells.

Toxicon
We report the cytotoxic effects of Lansbermin-I, a disintegrin from Porthidium lansbergii lansbergii venom, on HeLa cervical cancer cells but not on leukemic, non-tumorigenic peripheral blood mononuclear cells (PBMCs) or fibroblast lines.
