MiR-146b is a regulator of human visceral preadipocyte proliferation and differentiation and its expression is altered in human obesity.

Visceral obesity is an independent risk factor for metabolic syndrome, and abnormal fat accumulation is linked to increases in the number and size of adipocytes. MiR-146b was a miRNA highly expressed in mature adipocytes while very lowly expressed in human mesenchymal stem cells (hMSCs) and human visceral preadipocytes (vHPA). In this paper, we mainly focused on the roles of miR-146b in adipogenesis.

Metformin prevents LYRM1-induced insulin resistance in 3T3-L1 adipocytes via a mitochondrial-dependent mechanism.

We previously proposed that LYR motif containing 1 (LYRM1)-induced mitochondrial reactive oxygen species (ROS) production contributes to obesity-related insulin resistance. Metformin inhibits ROS production and promotes mitochondrial biogenesis in specific tissues. We assessed the effects of metformin on insulin resistance in LYRM1-over-expressing 3T3-L1 adipocytes.

Knockdown of LYRM1 rescues insulin resistance and mitochondrial dysfunction induced by FCCP in 3T3-L1 adipocytes.

LYR motif-containing 1 (LYRM1) was recently discovered to be involved in adipose tissue homeostasis and obesity-associated insulin resistance. We previously demonstrated that LYRM1 overexpression might contribute to insulin resistance and mitochondrial dysfunction. Additionally, knockdown of LYRM1 enhanced insulin sensitivity and mitochondrial function in 3T3-L1 adipocytes.

Untangling the transcriptome from fungus-infected plant tissues.

The development of sequencing technology allows low-cost generation of sequence data. The huge amount of raw sequence data now available has introduced many challenges associated with analysis of these large-scale data banks. For example, it is very important to distinguish materials of plant and fungal origin in fungus-infected plant tissue.

[Study of the correlation between the colorectal cancer Chinese medicine syndrome types and (excision repair cross-complementing 1, ERCC1) gene polymorphisms].

Objective: To explore the correlation between excision repair cross-complementing 1 (ERCC1) C8092A and C19007T gene polymorphisms and different Chinese medicine (CM) syndrome types of colorectal cancer (CC).

Methods: Ninety-nine patients with CC were syndrome typed as dampness-heat accumulation syndrome, qi stagnation with blood stasis syndrome, Pi-Shen yang deficiency syndrome, and Gan-Shen yin deficiency syndrome. The gene polymorphisms of excision repair cross-complementing 1 (ERCC1) C8092A and C19007T in different CM syndrome types of CC were examined by polymorphisms chain reaction amplification and direct sequencing, and analyzed statistically.
