Long noncoding RNA DNAH17-AS1 promotes tumorigenesis and metastasis of non-small cell lung cancer via regulating miR-877-5p/CCNA2 pathway.

A growing number of studies have revealed that long noncoding RNAs (lncRNAs) can function as important oncogenes or tumor suppressors. This study aimed to investigate the regulatory role of lncRNA DNAH17 antisense RNA 1 (DNAH17-AS1) on non-small cell lung cancer (NSCLC) and the underlying molecular mechanisms. We observed that the expression of DNAH17-AS1 and CCNA2 mRNA was distinctly upregulated in NSCLC specimens and cell lines, while miR-877-5p expression was significantly decreased.

lncRNA confers cisplatin resistance of non-small-cell lung cancer via regulation of miR185-5p-SIX1 axis.

Chemoresistance is a major obstacle for chemotherapy failure in non-small-cell lung cancer (NSCLC). lncRNAs are a class of pivotal regulators in various cancers, and the lncRNA is implicated in the progression of NSCLC. However, it is still unclear whether it regulates chemosensitivity.

[Study on cadmium absorption in pumpkin by atomic absorption spectrophotometry].

A study was carried out on the characteristic of cadmium absorption in pumpkin by atomic absorption spectrophotometer. The results show that the cadmium absorption amount in pumpkin increased with the increase in cadmium concentration. Meanwhile the cadmium absorption amount in pumpkin increased with time.

[Determination of trace elements in pumpkin by FAAS].

Conditions for simultaneous determination of multi-trace elements in pumpkin by FAAS were studied. K, Ca, Mg, Na, Zn, Cu, Mn, Fe, Co and Cr in different parts and different growth periods of pumpkin were determined, the relative standard deviation of the method is between 0.1% and 2.

[Spectrometric determination of trace elements in 'Jinguang' prunus mume var. bungo of different growth periods].

A study was carried out on the content of trace elements such as Ca, Fe, Zn, Mn and Cu of prunus mume var. bungo in different growth periods by WFX-110 atomic absorption spectrometry. The results indicated that the linear relationships of different elements within the limits of working curves are good and the range of the recovery is 98% -105%, hence showing that the results are satisfactory.
