They launched a contest, known as the " repression Challenge ," offering a $1,000 prize to anyone who could identify a pre-1800 literary example of traumatic memory that has been repressed by an ...

Vets Who Repress Traumatic Memories May Not Be Worse Off

... personality. The authors called for more research, while noting that their exclusive focus on male patients as well as their use of older PTSD and repression measures (which had been in effect during the initial CDC study) could limit the accuracy of their findings. The finding, they said, is important ...

Mach One Corporation Announces Hand Carried Product as a Potential Solution to Swine Flu (H1N1) Virus

... depended on the protein casein kinase 1-delta (and not the protein TGF-beta receptor) and led to activation of a tumor-suppressor gene and repression of a tumor-promoting gene. At the cellular level, FHL1, FHL2, and FHL3 inhibited the growth of a human tumor cell line both in vitro and when ...

Scripps research team unravels new cellular repair mechanism

... phase, in preparation for the subsequent S phase. The team has now shown that when such stalls occur, collectively referred to as DNA stress, Nrm1's repression of the G1 genes is blocked, allowing those genes to be turned back on. This presumably enables production of proteins needed to correct the problem ...

How embryonic stem cells develop into tissue-specific cells demonstrated

... this process, resolving a long-standing question as to whether the stem cells achieve their development through selective activation or selective repression of genes. The collaborative research group, which included Dr. Eran Meshorer of the Department of Genetics at the Silberman Institute of Life ...

Is increased Slug expression associated with the progression to esophageal cancer?

... invasiveness and metastasis. The main mechanism by which cell-cell adhesion is repressed in oesophageal adenocarcinoma is thought to be through the repression of the cell adhesion molecule E-cadherin. This study reports that a potential mechanism by which E-cadherin could be silenced is through over ...

Unsuspected protein determines resistance to breast cancer treatment

... the authors to propose that CDK10 normally represses the ETS2 transcription factor and that the loss of CDK10 expression results in relief of ETS2 repression and upregulation of c-RAF transcription. Enhanced c-RAF activation results in activation of mitogen-activated protein kinase and increased cyclin D1 ...

Regulation of cell proliferation by the OGF-OGFr axis is dependent on nuclear localization signals

... 5 hours, and transit into the nucleus took 8 hours; OGFr remained in the nucleus for up to 8 days. Transport through the nuclear pore and repression of cell proliferation required two of the three nuclear localization signals (NLS) in OGFr. These results show that the pathway for regulating the ...

CSHL team traces extensive networks regulating alternative RNA splicing

... where the splicing factors Fox-1 and Fox-2 attach, or bind, to unedited target RNA transcripts. "The effect of splicing factors on the activation or repression of splicing often depends on the location and context of the RNA sequences they bind," Dr. Krainer explained. It was known that the two proteins ...
