In this task, you are given an abstract of article. Your task is to generate title for this article. Preferred titles are under thirty words.

Example Input: Fast excitatory neurotransmission is mediated largely by ionotropic glutamate receptors (iGluRs), tetrameric, ligand-gated ion channel proteins comprised of three subfamilies, AMPA, kainate and NMDA receptors, with each subfamily sharing a common, modular-domain architecture. For all receptor subfamilies, active channels are exclusively formed by assemblages of subunits within the same subfamily, a molecular process principally encoded by the amino-terminal domain (ATD). However, the molecular basis by which the ATD guides subfamily-specific receptor assembly is not known. Here we show that AMPA receptor GluR1- and GluR2-ATDs form tightly associated dimers and, by the analysis of crystal structures of the GluR2-ATD, propose mechanisms by which the ATD guides subfamily-specific receptor assembly.
Example Output: Crystal structure and association behaviour of the GluR2 amino-terminal domain.

Example Input: Although it has now been 10 years since the first cloned mammals were generated from somatic cells using nuclear transfer (NT), most cloned embryos usually undergo developmental arrest prior to or soon after implantation, and the success rate for producing live offspring by cloning remains below 5%. The low success rate is believed to be associated with epigenetic errors, including abnormal DNA hypermethylation, but the mechanism of "reprogramming" is unclear. We have been able to develop a stable NT method in the mouse in which donor nuclei are directly injected into the oocyte using a piezo-actuated micromanipulator. Especially in the mouse, only a few laboratories can make clones from adult somatic cells, and cloned mice are never successfully produced from most mouse strains. However, this technique promises to be an important tool for future research in basic biology. For example, NT can be used to generate embryonic stem (NT-ES) cell lines from a patient's own somatic cells. We have shown that NT-ES cells are equivalent to ES cells derived from fertilized embryos and that they can be generated relatively easily from a variety of mouse genotypes and cell types of both sexes, even though it may be more difficult to generate clones directly. In general, NT-ES cell techniques are expected to be applied to regenerative medicine; however, this technique can also be applied to the preservation of genetic resources of mouse strain instead of embryos, oocytes and spermatozoa. This review describes how to improve cloning efficiency and NT-ES cell establishment and further applications.
Example Output: Production of cloned mice and ES cells from adult somatic cells by nuclear transfer: how to improve cloning efficiency?

Example Input: BACKGROUND Corin has been suggested to be associated with hypertension by cell- and animal-based studies. However, the association still lacks population-based evidence which critically promotes translation from basic research to clinical and preventive practice. Here, we aimed to explore the association in a general population of China.
METHODS From January to May 2010, we conducted a cross-sectional study in 2,498 participants aged above 30 years, residing in Gusu district of Suzhou. Serum soluble corin and blood pressure were measured.
RESULTS Hypertensive participants had a higher level of serum corin than nonhypertensive participants (median (interquartile range): 1,836.83 (1,497.85-2,327.87) pg/ml vs. 1,579.14 (1,322.18-1,956.82) pg/ml, P < 0.001). Higher serum corin was positively associated with prevalent hypertension (odds ratio (OR) = 2.01, P < 0.001). In the multiple analysis, participants in the third (OR = 1.43, P = 0.007) and fourth (OR = 1.96, P < 0.001) quartiles had significantly increased odds of hypertension compared to those in the lowest quartile of serum corin. ORs of hypertension positively and significantly increased with serum corin levels (P for trend <0.001). Further subgroup analysis showed that ORs of hypertension associated with high corin (over the median level of serum corin: 1,689.20 pg/ml) were still significant in subgroups by age, body mass index, total cholesterol, low-density lipoprotein cholesterol, and fasting plasma glucose (all P < 0.05).
CONCLUSIONS Our study showed that hypertensive participants had an increased serum corin level compared to those without hypertension. This finding suggests that corin may play a role in the pathology of hypertension.
