Sonneborn and the Cytoplasm [PDF]
Genetics, 2006 IN the late 1930s when Tracy Sonneborn was in graduate school and just starting his work on the genetics of protozoa, classical studies on genetics were almost finished. The second edition of Principles of Genetics by E. W. Sinnott and L. C. Dunn (1932) that appeared in that period was quite sophisticated, containing a good account of chromosome theory,

Cytoplasmic domains in eggs [PDF]
Trends in Cell Biology, 1994 One way of organizing the body plan of a developing embryo is to establish domains in the egg with distinct compositions in defined spatial relationships to one another: when the egg divides up, these domains segregate preferentially to certain regions of the embryo and influence their development.

eLife, 2016 Cells can enter into a dormant state when faced with unfavorable conditions. However, how cells enter into and recover from this state is still poorly understood. Here, we study dormancy in different eukaryotic organisms and find it to be associated with

The entry of diphtheria toxin into the mammalian cell cytoplasm: evidence for lysosomal involvement [PDF]
, 1980 Lysosomotropic amines, such as ammonium chloride, are known to protect cells from the cytotoxic effects of diphtheria toxin. These drugs are believed to inhibit the transport of the toxin from a receptor at the cell exterior into the cytoplasm where a ...

Frontiers in Plant Science, 2017 Betalains replace anthocyanins as color pigments in most families of Caryophyllales. Unlike anthocyanins, betalains are derived from tyrosine via three enzymatic steps: hydroxylation of L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA; step 1), and ...

Emerging Roles of Long Noncoding RNAs in the Cytoplasmic Milieu
Non-Coding RNA, 2020 While the important functions of long noncoding RNAs (lncRNAs) in nuclear organization are well documented, their orchestrating and architectural roles in the cytoplasmic environment have long been underestimated.

Parathyroid Adenoma Completely Impacted within the Thyroid Gland: A Case Report [PDF]
Journal of Clinical and Diagnostic Research, 2016 Ectopic parathyroid adenoma can be seen in various locations. Sometimes ultrasound and even fine needle aspiration studies cannot distinguish this lesion from thyroid lesions. A 29-year-old woman with a prominent nodule of left thyroid lobe was referred

FoxK1 and FoxK2 in insulin regulation of cellular and mitochondrial metabolism [PDF]
, 2019 A major target of insulin signaling is the FoxO family of Forkhead transcription factors, which translocate from the nucleus to the cytoplasm following insulin-stimulated phosphorylation.

Delayed kinetics of poliovirus RNA synthesis in a human cell line with reduced levels of hnRNP C proteins. [PDF]
, 2010 The hnRNP C heterotetramer [(C1(3))C2] binds RNA polymerase II transcripts in the nucleus, along with other proteins of the core hnRNP complex, and plays an important role in mRNA biogenesis and transport.

Apoptosis propagates through the cytoplasm as trigger waves
Science, 2018 Visualizing a traveling wave of cell death When diffusion is too slow for communication over long distances, cells can use waves of chemical activity. By using fluorescent probes and microscopy, Cheng and Ferrell show that in frog eggs (which are very ...
