Saporin-S6: A Useful Tool in Cancer Therapy
Thirty years ago, the type 1 ribosome-inactivating protein (RIP) saporin-S6 (also known as saporin) was isolated from Saponaria officinalis L. seeds. Since then, the properties and mechanisms of action of saporin-S6 have been well characterized, and it ...

Nei-like 1 (NEIL1) excises 5-carboxylcytosine directly and stimulates TDG-mediated 5-formyl and 5-carboxylcytosine excision [PDF]
Thymine DNA glycosylase (TDG) and Nei-like 1 (NEIL1) have both been implicated in the base excision repair step of active DNA demethylation. The robust glycosylase activity of TDG on DNA substrates containing 5-formylcytosine (5fC) or 5-carboxylcytosine (

Re-expression of IGF-II is important for beta cell regeneration in adult mice [PDF]
Background The key factors which support re-expansion of beta cell numbers after injury are largely unknown. Insulin-like growth factor II (IGF-II) plays a critical role in supporting cell division and differentiation during ontogeny but its role in the

Oxidative DNA damage is instrumental in hyperreplication stress-induced inviability of Escherichia coli [PDF]
En Escherichia coli, un aumento en la forma unida de ATP del iniciador de proteína DnaA da resultados en hiperiniciación e inviabilidad. Aquí, mostramos que dicha replicación de estrés es tolerada en el crecimiento anaeróbico.

An effort to make sense of antisense transcription in bacteria [PDF]
Analysis of bacterial transcriptomes have shown the existence of a genome-wide process of overlapping transcription due to the presence of antisense RNAs, as well as mRNAs that overlapped in their entire length or in some portion of the 5'- and 3'-UTR ...

APE1/Ref-1 Role in Redox Signaling: Translational Applications of Targeting the Redox Function of the DNA Repair/Redox Protein APE1/Ref-1 [PDF]
The heterogeneity of most cancers diminishes the treatment effectiveness of many cancer-killing regimens. Thus, treatments that hold the most promise are ones that block multiple signaling pathways essential to cancer survival.

Several studies highlight the identification of some enzymes with additional abilities, especially those involved in metabolic pathways and/or host defence processes, classified as multitasking proteins. In this context, we report the characterization of melleatin (17.5-kDa), a multitasking enzyme isolated from Armillaria mellea fruiting bodies ...
