概括
这次元分析研究了微RNA单核酸多态 (miRNA-SNPs) 和儿科急性淋巴细胞白血病 (ALL) 风险. 虽然总体结果是不确定的,但针对特定国家的分析表明miRNA-SNP与ALL的关联存在基于种族的差异.

背景情况:
- 微RNA (miRNA) 单核酸多态 (miRNA-SNPs) 与各种癌症有关.
- 之前对miRNA-SNP和儿科急性淋巴细胞白血病 (ALL) 的研究已经产生了不一致的结果.
- 需要进行全面的元分析来澄清miRNA-SNPs与儿科ALL风险之间的关联.
研究的目的:
- 进行元分析以统计评估miRNA-SNPs与儿科ALL风险之间的关联.
- 通过使用各种遗传模型,研究这种关联中的潜在国家特异性差异.
主要方法:

11.9K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

16.0K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
