Boheler KR, Joodi RN, Qiao H, Juhasz O, Urick AL, Chuppa SL, Gundry RL, Wersto RP, Zhou R.
PMID: 21912557
Stem Cells Int. 2011;2011:214203. doi: 10.4061/2011/214203. Epub 2011 Sep 06.

Pluripotent stem cells represent one promising source for cell replacement therapy in heart, but differentiating embryonic stem cell-derived cardiomyocytes (ESC-CMs) are highly heterogeneous and show a variety of maturation states. In this study, we employed an ESC clonal line...

BMC research notes

Kanikarla-Marie P, Ronald S, De Benedetti A.
PMID: 21255428
BMC Res Notes. 2011 Jan 21;4:13. doi: 10.1186/1756-0500-4-13.

BACKGROUND: The S. cerevisiae mating type switch model of double-strand break (DSB) repair, utilizing the HO endonuclease, is one of the best studied systems for both Homologous Recombination Repair (HRR) and direct ends-joining repair (Non-Homologous Ends Joining - NHEJ)....

Establishment of a colorectal cancer nude mouse visualization model of HIF-1α overexpression.

The aim of the present study was to establish a model of tumor cell growth and visualize HIF-1α overexpression in a nude mouse xenograft model of colorectal cancer (CRC). In the study, HIF-1α lentiviral vector and helper plasmid were...

The effect of puromycin on the early cleavage cycles and morphogenesis of the pond snailLymnaea stagnalis.

Wilhelm Roux's archives of developmental biology

Boon-Niermeijer EK.
PMID: 28304647
Wilehm Roux Arch Dev Biol. 1975 Mar;177(1):29-40. doi: 10.1007/BF00848625.

The susceptibility of eggs ofLymnaea to puromycin was investigated during the first four cleavage cycles.The eggs are susceptible with respect to cleavage delay during the first half of the cell cycle, including cytokinesis, the phase of DNA replication, and...

Extracellular vesicles of ETV2 transfected fibroblasts stimulate endothelial cells and improve neovascularization in a murine model of hindlimb ischemia.

Cytotechnology

Van Pham P, Vu NB, Dao TT, Le HT, Phi LT, Huynh OT, Truong MT, Nguyen OT, Phan NK.
PMID: 28466428
Cytotechnology. 2017 Oct;69(5):801-814. doi: 10.1007/s10616-017-0095-2. Epub 2017 May 02.

Ischemia are common conditions related to lack of blood supply to tissues. Depending on the ischemic sites, ischemia can cause different diseases, such as hindlimb ischemia, heart infarction and stroke. This study aims to evaluate how extracellular vesicles (EVs)...

Ecdysone Regulated RNA synthesis in Drosophila larval salivary glands.

Endocrine regulations

Farkas R.
PMID: 10993979
Endocr Regul. 1995 Sep;29(3):171-185.

The changes in total and ribosomal RNA (rRNA) synthesis in cultured larval salivary glands of Drosophila in response to steroid hormone ecdysone have been studied. By using the incorporation of [3H]-uridine or [32P]-UTP into salivary gland cells, followed by...

Transcription and Translation of Sendai Virus Hemagglutinin-neuraminidase (HN) in Mammalian Cells.

Sheng wu hua xue yu sheng wu wu li xue bao Acta biochimica et biophysica Sinica

Hu JH, Qi B, Nakanishi M, Qi YP.
PMID: 12075445
Sheng Wu Hua Xue Yu Sheng Wu Wu Li Xue Bao (Shanghai). 2000;32(3):229-234.

Sendai virus hemagglutinin-neuraminidase was expressed in COS-7 cells. LLCMK(2) cells were transfected with expression plasmids harboring HN, namely pJH3, pJH4 or pJH7, and were passaged conti-nuously under the presence of hygromycin or puromycin to get antibiotic-resistant clones, which had...

Peroxidase Release Induced by Ozone in Sedum album Leaves: Involvement of Ca.

Plant physiology

Castillo FJ, Penel C, Greppin H.
PMID: 16663520
Plant Physiol. 1984 Apr;74(4):846-51. doi: 10.1104/pp.74.4.846.

The effect of ozone was studied on the peroxidase activity from various compartments of Sedum album leaves (epidermis, intercellular fluid, residual cell material, and total cell material). The greatest increase following a 2-hour ozone exposure (0.4 microliters O(3) per...

Cell Wall Regeneration around Protoplasts Isolated from Convolvulus Tissue Culture.

Plant physiology

Horine RK, Ruesink AW.
PMID: 16658192
Plant Physiol. 1972 Oct;50(4):438-45. doi: 10.1104/pp.50.4.438.

Protoplasts of Convolvulus arvensis L. tissue culture regenerated a wall-like structure within 3 days in culture. Although unusually electron dense and atypically amorphous in the electron microscope, this structure could be digested with Myrothecium cellulase but was resistant to...

The regulation of activity of the enzymes involved in the assimilation of nitrate by higher plants.

The Biochemical journal

Ingle J.
PMID: 16742412
Biochem J. 1966 Sep;100(3):577-88. doi: 10.1042/bj1000577.

1. Possible mechanisms regulating the activities of three enzymes involved in nitrate assimilation, nitrate reductase, nitrite reductase and glutamate dehydrogenase, were studied in radish cotyledons. 2. Nitrate-reductase and nitrite-reductase activities are low in nitrogen-deficient cotyledons, and are induced by...
