Comparative understanding of metal hyperaccumulation in plants: a mini-review.

Hyperaccumulator plants are ideal models for investigating the regulatory mechanisms of plant metal homeostasis and environmental adaptation due to their notable traits of metal accumulation and tolerance. These traits may benefit either the biofortification of essential mineral nutrients or the phytoremediation of nonessential toxic metals. A common mechanism by which elevated expression of key genes involved in metal transport or chelation contributes to hyperaccumulation and hypertolerance was proposed mainly from studies examining two Brassicaceae hyperaccumulators, namely Arabidopsis halleri and Noccaea caerulescens (formerly Thlaspi caerulescens).

The role of single strand break repair pathways in cellular responses to camptothecin induced DNA damage.

Efficient DNA repair is critical for cell survival following exposure to DNA topoisomerase I (Top1) inhibitors camptothecin, a nature product from which the common chemotherapeutic drugs irinotecan and topotecan are derived. The camptothecin-derived agents exert their antitumor activities by specifically stabilizing the Top1-DNA covalent complexes (Top1cc) and blocking the DNA religation step. When exposed to these DNA damage agents, tumor cells quickly activate DNA damage response.

Comprehensive analysis of the association of EGFR, CALM3 and SMARCD1 gene polymorphisms with BMD in Caucasian women.

Summary: Three genes, including EGFR (epidermal growth factor receptor), CALM3 (calmodulin 3, calcium-modulated protein 3) and SMARCD1 (SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily d member 1), play different roles in bone and/or fat metabolism in Caucasian women. In this population-based investigation of 870 unrelated postmenopausal Caucasian women, CALM3 polymorphisms were significantly associated with femoral neck bone mineral density (FNK BMD), hip BMD and spine BMD. Age and tobacco status also affected BMD levels and were therefore corrected for in our statistical analysis.
