J Pharm Biomed Anal 2021; 209:114495. [PMID: 34864355 DOI: 10.1016/j.jpba.2021.114495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/09/2021] [Accepted: 11/23/2021] [Indexed: 11/27/2022]
Abstract
The secretions of the venom glands, dry skin and whole body of several Bufo species have been used as traditional medicines in East Asia to treat heart failure and cancer. Due to the highly similar morphological features of Bufo species and their derived commercial crude drugs, along with the high similarity of chemical composition of the secretions of venom glands, it is very challenging to identify the medicinal toads and the related crude drugs. The cyt-b sequences provide useful information to authenticate medicinal Bufo species. Based on the cyt-b sequences, a simple PCR-RFLP method was established for the identification of the medicinally used Bufo species as well as their derived crude drugs. The 23 specimens from three medicinally used Bufo species, B. bufo gargarizans (Bbg), B. melanostictus (Bm) and B. raddei (Br), were clearly divided into 3 groups according to the sequences of amplified cyt-b regions, which could be digested by specific restriction enzymes NcoI, EcoRV and BstXI, respectively. Then the specific PCR-RFLP method was further used to identify 9 samples of commercial crude drugs even with serious degradation of DNA, and all nine samples were identified as B. bufo gargarizans. The method is suitable for identification of medicinally used Bufo species and the related crude drugs.

Sun WH, Chen DQ, Carballar-Lejarazu R, Yang Y, Xiang S, Qiu MY, Zou SQ. Genetic diversity and population structure of Euscaphis japonica, a monotypic species. PeerJ 2021; 9:e12024. [PMID: 34513336 PMCID: PMC8395579 DOI: 10.7717/peerj.12024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 07/29/2021] [Indexed: 01/28/2023] Open
Abstract
Background Understanding plant genetic diversity is important for effective conservation and utilization of genetic resources. Euscaphis japonica (Thunb.) Dippel, is a monotypic species with high phenotypic diversity, narrow distribution, and small population size. In this study, we estimated the genetic diversity and population structure of E. japonica using nine natural populations and inter-simple sequence repeat (ISSR) markers. Our results could provide a theoretical reference for future conservation and utilization of E. japonica. Results We obtained a total of 122 DNA bands, of which 121 (99.18%) were polymorphic. The average number of effective alleles (Ne = 1.4975), Nei’s gene diversity index (H = 0.3016), and Shannon’s information index (I = 0.4630) revealed that E. japonica possessed a high level of genetic diversity. We observed that E. japonica consisted of both deciduous and evergreen populations. UPGMA tree showed that the evergreen and deciduous E. japonica form a sister group. There is little genetic differentiation among geographic populations based on STRUCTURE analysis. The Dice’s similarity coefficient between the deciduous and evergreen populations was low, and the Fst value was high, indicating that these two types of groups have high degree of differentiation. Conclusion Rich genetic diversity has been found in E. japonica, deciduous E. japonica and evergreen E. japonica populations, and genetic variation mainly exists within the population. The low-frequency gene exchange between deciduous and evergreen populations may be the result of the differentiation of deciduous and evergreen populations. We suggest that in-situ protection, seed collection, and vegetative propagation could be the methods for maintenance and conservation of E. japonica populations.

Abstract
Cancer cell lines are used worldwide in biomedical researches, and data interpretation solely depends on unambiguous attribution of those respective cell lines to its original sources. Approximately one-third of all cell lines have an origin other than that assumed, leading to invalid results. It is necessary to characterize the origin of cell lines. Short-tandem-repeat (STR) fingerprinting (DNA fingerprinting) is the method for characterization of genetic identity in cultured cell lines under certain experimental conditions. We showed the fingerprinting profiles in a summed and unidentified human cancer cell line comparison to HCC1954 cell line, revealing marked alterations in DNA fingerprinting profiles up to fourteen STR loci from 16 loci. Furthermore, Sanger DNA sequencing showed no c.3140A > G heterozygous mutation in the PIK3CA gene of this suspected HCC1954 cell line. In addition, we showed the fingerprinting profiles in an unidentified cancer cell line comparison to SiHa cervical cell line, revealing same DNA fingerprinting profiles. In conclusion, we have successfully authenticated and identified both suspected HCC1954 and SiHa cell lines by STR analysis and DNA sequencing. STR analysis combined DNA sequencing may be very useful to evaluate genotypes of cancer cell lines in our cancer studies, as well as in judicial authentication and forensic sciences.
