Kaposiform hemangioendothelioma: Diagnosis and treatment

Pediatric Investigation, EarlyView.
Vascular endothelial growth factor‐C (VEGF‐C)/vascular endothelial growth factor receptor‐3 (VEGFR‐3) and angiopoietin‐2 (Ang‐2)/tyrosine kinase with immunoglobulin‐like and EGF‐like domain 2 (TIE2) signaling pathways play an important role in lymphangiogenesis.

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

The seco-iridoid pathway from Catharanthus roseus [PDF]

Nature Communications, 2014
The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum of high-value pharmacological and insect-repellent activities. Vinblastine and vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels ...

OsRALF26 Serves as an Endogenous Signal Recognised by XA21 to Promote Robust and Distal Resistance in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant immune receptors detect both microbe‐derived and endogenous signals to activate defences. XA21, a rice immune receptor, confers strong race‐specific resistance to a subset of Xanthomonas oryzae pv. oryzae (Xoo) strains by recognising the microbial sulphated peptide RaxX.

A Catharanthus roseus Fe(II)/α-ketoglutarate-dependent dioxygenase catalyzes a redox-neutral reaction responsible for vindolinine biosynthesis

Nature Communications, 2022
Catharanthus roseus is the source for anticancer drug vinblastine and other medicinal monoterpenoid indole alkaloids. Here the authors characterize an Fe/2OG dioxygenase, vindolinine synthase, which catalyzes an unusual redox-neutral reaction leading to ...
