There are currently no approved effective therapies for Alzheimer's disease (AD). AD is a classic, multifactorial, complex syndrome. Thus, a polypharmacological or multitargeted approach to AD might provide better therapeutic benefits than monotherapies. However, it remains elusive which biological processes and biomolecules involved in the pathophysiologic processes of AD would constitute good targets for multitargeted therapy. This study proposes that a co-module, consisting of biological processes, cellular pathways and nodes, in a molecular subnetwork perturbed by different therapeutic drugs may be the optimal therapeutic target for an AD multitarget-based intervention. Based on this hypothesis, genes regulated in the hippocampus and cortex of senescence-accelerated mouse prone-8 (SAMP8) mice by traditional Chinese medicine (TCM) prescriptions with different constituents and the same beneficial effects on AD, including the decoctions Liu-Wei-Di-Huang (LW), Ba-Wei-Di-Huang (BW), Danggui-Shaoyao-San (DSS), Huang-Lian-Jie-Du (HL) and Tiao-Xin-Fang (TXF), were investigated via cDNA microarray, and the perturbed subnetworks were constructed and interpreted. After comparing 15 perturbed subnetworks based on genes affected by LW, BW, HL, DSS and TXF, the results showed that the most important common nodes perturbed by these interventions in the brains of SAMP8 mice were RPS6KA1 and FHIT, and that other important common nodes included UBE2D2, STUB1 and AMFR. These five drugs simultaneously and significantly disturbed the regulation of apoptosis and protein ubiquitination among biological processes. These nodes and processes were key components of the co-module regulated by therapeutic drugs in a molecular subnetwork of AD. These results suggest that targeting candidate regulator of apoptosis and protein ubiquitination might be effective for AD treatment, and that RPS6KA1, FHIT, UBE2D2, STUB1 and AMFR might be optimal combinational targets of an AD multitarget-based therapy.

Juvenile in vitro embryo transfer is an important animal reproductive technology that can shorten the generation interval of livestock, explore the reproductive potential of dams with excellent genetic traits, accelerate genetic progress and production efficiency of the herd, and provide a wealth of genetic resources for livestock breeding. However, oocytes from kids do not develop as well as those from female goats during in vitro maturation. To identify differences during different stages of oocyte maturation, we used single cell transcriptome sequencing to compare gene expression in mature oocytes from kids and female goats. We identified 1086 differentially expressed genes in mature oocytes from kids and female goats. Of these, we observed upregulated expression in 355 genes and downregulated expression in 435 genes. The differentially expressed genes were involved in a total of 245 different pathways; of which 30 were significant (P <= 0.05). We used real-time quantitative polymerase chain reaction to screen and verify the expression of five genes specifically involved in oocyte maturation (MOS, RPS6KA1, CPEB1, ANAPC13, and CDK1). Further study of these genes will be of great importance for improving the reproductive performance of Haimen white goats.
