Expression of ANCR in nasopharyngeal carcinoma patients and its clinical significance.

Anti-differentiation non-coding RNA (ANCR), a long non-coding RNA, is involved in the development, progression and metastasis of various human cancers. However, its clinical significance in nasopharyngeal carcinoma (NPC) still remains unknown. This study aimed to investigate ANCR expression and its clinical significance in NPC.

The formation and extinction of fear memory in tree shrews.

Fear is an emotion that is well-studied due to its importance for animal survival. Experimental animals, such as rats and mice, have been widely used to model fear. However, higher animals such as nonhuman primates have rarely been used to study fear due to ethical issues and high costs.
