Cellular responses to excess phospholipid.
Phosphatidylcholine (PtdCho) is the major membrane phospholipid in mammalian cells, and its synthesis is controlled by the activity of CDP:phosphocholine cytidylyltransferase (CCT). Enforced CCT expression accelerated the rate of PtdCho synthesis. However, the amount of cellular PtdCho did not increase as a result of the turnover of both the choline and glycerol components of PtdCho. Metabolic ...
متن کاملGrowth and accumulation responses of Populus nigra L. exposed to hexavalent chromium excess
Phytoremediation of heavy metals is employed as a technological approach for a non-destructive remediation of contaminated soils. One of the most recently studied tree species used in phytoremediation applications are poplars. In this study, the one-year old rooted seedlings of Populus nigra L. used to decontaminate hexavalent chromium-contaminated soils. Five treatments of Cr (VI) supply (were...
متن کاملCellular Host Responses to Gliomas
BACKGROUND Glioblastoma multiforme (GBM) is the most aggressive type of malignant primary brain tumors in adults. Molecular and genetic analysis has advanced our understanding of glioma biology, however mapping the cellular composition of the tumor microenvironment is crucial for understanding the pathology of this dreaded brain cancer. In this study we identified major cell populations attract...
متن کاملMicroRNA responses to cellular stress.
Recent work has begun to explore the instrumental role that small noncoding RNA species, particularly microRNAs (miRNA), have both in classifying human tumors and in directing embryonic development. These studies suggest that developmental programs in essentially all organisms studied are set, in part, by varied expressions of miRNAs and that neoplasia is characterized by altered expression of ...
متن کاملCellular responses to DNA damage.
For many years, the study of the regulation of the SOS network was complicated by both the complexities of the responses and the interrelationships of the key regulatory elements. However, recently the application of powerful genetic and molecular biological techniques has allowed us to gain a detailed picture of the regulation of this complex network. The network is now known to consist of mor...
