Strange Science: The Rocky Road to Modern Paleontology and Biology

by misskitty4280

STIM1 就是鈣池調控鈣離子通道 (store-operated channels) 嗎?

by YukuanMark
1986年美國國家衛生研究院科學家Putney J教授提出填充式鈣離子湧入理論(capacitative calcium influx),這理論也就是現在常稱的鈣池調控鈣離子通道理論(store-operated channels)。在這個理論中,Putney J教授認為:在非興奮細胞中,當細胞內質網中鈣離子的含量下降到一定程度時,就會啟動一些未知機制來打開細胞膜上的鈣池調控鈣離子通道(store-operated channels),讓細胞外的鈣離子進入細胞內,進而將鈣離子填補回內質網。

「細胞」改頭換面!

by YukuanMark
由"Cell press"所出版的一系列期刊一直在生命科學界扮演執牛耳的角色,在"Cell press"所發行的學術期刊中,又以"Cell"的影響力為最。許多科學家(包括筆者本人)都將能把自己辛苦的研究成果發表在"Cell"視為最高的理想與榮耀。
