如果我是你,第一要做的,就是确定这个5% p53 expression。 你得非常肯定这个变化是真的,否则可能是瞎忙活。 第二要做的,比较快的,give them some DNA damage or other tumorigenic drugs/chemicals,然后观察肿瘤发生的变化。 如果你那个5%的表达量是真的,什么都不做,你的KO Mice也会自然产生肿瘤并很快死 掉。
Is 5% of p53 expression under normal condition or after DNA damage induction ? Is it mRNA expression or protein expression? This could give important insights into mechanistic study. By the way, if you want to get a good paper out of this, patient data is key . Get some tumor samples and measure the expression level of your tumor supressor. Correlate with prognosis etc...
Thank you for your suggestions.Your questions are answered in the following. Is 5% of p53 expression under normal condition or after DNA damage induction ? Is it mRNA expression or protein expression? This could give important insights into mechanistic study. Without any treatment, p53 protein level in KO mouse skin is downregulated to 5%---50% level of wt mouse skin. By the way, if you want to get a good paper out of this, patient data is key Get some tumor samples and measure the expression level of your tumor supressor. Correlate with prognosis etc... Great idea! I'll suggest to my boss looking for collaboration. Thanks again.

LZ already had significant data regarding tumor suppressor activity of the protein - "干掉我的这个老鼠基因能促进癌基因诱导的皮肤癌,我现在已有足够的老 鼠数据下这个结论." It takes a long time to find collaboration and prepare the paperwork to acquire patient samples. For CNS paper in oncology, most have some patient data to support the clinical significance.
actually it is not difficult to find a collaborator with tumor tissue bank, such as state cancer registry

actually my point is that you can find collaborator with eatablished tumor bank. You don't want to look for "fresh" clinical sample, which is hard.
