Molecular cloning and sequence analysis of the gene encoding interleukin‐6 of the giant panda (Ailuropoda melanoleuca)

In the present study, the cloning and sequence analysis of interleukin‐6 (IL‐6) from the giant panda (Ailuropoda melanoleuca) were described. Sequencing revealed that IL‐6 complementary DNA contains a 636 base‐pair open reading frame encoding 211 amino acids. Homology analyses indicated that the identity levels of nucleotide and deduced amino acid sequences of IL‐6 between the giant panda and other species in Carnivora ranged from 90.5% to 85.6% and from 82.9% to 76.5%, respectively. Phylogenetic analyses based on nucleotide and amino acid sequences showed that the harbour seal shared a closer relationship with the giant panda than other carnivores (ursids not included). The functionally important domains and sites that have previously been recognized in other carnivores were all observed in the IL‐6 sequence of the giant panda. These findings suggest that the complementary DNA fragment cloned is indeed the IL‐6 molecule with biological activity and can be used in immunological studies of the giant panda.

Analysis of the characteristic sequence of intein and revision of its motifs

Since the first intein (Sce VMA) was found inSaccharomydes cerevisiae ATPases gene in 1990, more and more inteins were identified. It is necessary to analyze the new inteins to understand the sequence charateristics of inteins. By searching protein and nucleic acid database systematically, 101 inteins were found, of which 69 inteins contain homing endonuclease motifs. We only analyze the 69 inteins since most inteins are the classic inteins with homing endonuclease motifs. We found that the distribution of these inteins is particular among species and protein. By multiple sequence alignment, some new sequence characteristics were found and the motifs described previously were revised.     

一个推广的Borel强大数定律的改进

Borel通过研究Bernoulli试验,首先给出了其强大数定律,已有文献给出了一个推广的Borel强大数定律.作者改进了这个结果,将其中的条件dn=O(1/n)减弱为dn=O(1/nα),α>0.另外,将此结果推广到有界的随机变量序列的情形,给出其Borel强大数定律.
