一些科学家怀疑真正的杀手是由一种有毒的真菌感染的,这些真菌像笨拙的陷阱一样在坟墓中处于休眠状态: aspergillus flavus flavus 。 Now the fungus is again at the centre of intrigue after researchers in the US crafted the deadly spores into a compound that can kill cancer cells.
In the search for new drugs, scientists have been studying a group of natural molecules called RiPPs (ribosomally synthesised and post-translationally modified peptides).
Many of these tiny proteins have proved toxic to infectious microbes and cancer cells, which is why researchers are on the hunt for new types of RiPPs to test their medical potential.
“We often think of fungi as causing disease or food spoilage, but this is an example of them holding the key to treating diseases.”

已经在细菌中发现了数千种这些分子,但只有少数来自真菌的分子,这就是为什么宾夕法尼亚大学的研究人员以 aspergillus 。
寻找与人类相互互动的ripp ripp的新类型的原因。然后,一些分子阻止了癌细胞的生长。
科学家随后添加了蜜蜂喂养其幼虫的脂肪分子。 The fat molecule or “lipid” helped the cancer-busting RiPPs to infiltrate leukemia cells, and together the experimental combination performed as effectively as two existing leukemia drugs.
Advertisement“Cancer cells divide uncontrollably,” said 自然化学生物学研究的高级作家Xue Gao副教授。 “这些化合物阻止了微管的形成,这对于细胞分裂至关重要。”
