Pre-mRNA processing factor 19 (PRPF19) is a multifaceted protein and participates in DNA damage response and pre-mRNA processing.The role of PRPF19 in cancer is unclear.Here,we report that the expression of PRPF19 in human tongue cancer is associated with unfavorable prognosis.Over-expression of PRPF19 promotes while knockdown of PRPF19 inhibits tongue cancer cell migration,proliferation,and tumor growth.Overexpression of PRPF19 increases the resistance of tongue cancer cells to radiation and cisplatin treatment.Furthermore,PRPF19 regulates the expression of solute carrier family 40 member 1 (SLC40A1) and mono-ADP ribosylhydrolase 2 (MACROD2),knockdown of SLC40A1 or MACROD2 decreases the sensitivity of tongue cancer cells to radiation and cisplatin treatment.Thus,our results establish a key role of PRPF19 in tongue cancer growth and chemoradiotherapy resistance,targeting PRPF19 would be an effective therapeutic strategy for tongue cancer,especially for those resistant to chemoradiotherapy.

“科学探究”素养本质上是通过个体运用科学探究的方法解决各子环节问题体现出来的.不同子问题的解决需要不同的认知策略和必要技能.教师只有厘清具体课堂学习中所遇到的各子问题解决的策略,才有可能帮助学生运用科学方法解决子问题.而课堂时间和资源有限,不可能为每一位学生提供解决问题的完整经历,教师应综合课外活动和课堂学习中问题解决来实现对学生科学探究素养的培养.
量子力学早已成为当代文明一个重要基础,量子科技正在蓬勃发展,包括量子信息和量子计算.从技术到理论,我们又都需要继续量子革命.本文回顾量子概念的起源和量子力学的发展,阐述了量子力学的本质是一种特别的概率性描述,解释了量子力学是整个微观物理学的理论框架,强调了它在天体物理方面的体现,还介绍了量子力学的丰富应用和对人类文明的深刻影响.然后总结了“量子”一词的含义,讲解了量子叠加、量子比特、量子纠缠、量子信息与量子计算,以及薛定谔猫、退相干和量子多世界等基本问题.
明代李时珍撰写的《本草纲目》是科学的史诗,更是实用的宝典.2011年,《本草纲目》与《黄帝内经》一起,被联合国教科文组织列入了世界记忆名录.这也是到目前为止,被列入其中的、仅有的两部来自中国的医药著作.英国生物学家达尔文曾将《本草纲目》誉为“中国古代的百科全书”.典籍中所列条目清晰、旁征博引,诸项分列释名、集解、修治、主治、发明、附方等条目,为前人所载正误,为后人所思启示.书中内容涉及了中国人的一天、中国人的一年、中国人的一生,既探讨了科学的分类体系,也阐释了日常生活中菜篮子、米口袋、大果篮当中的学问.
