Evaluating miR-137 Effects on HTR-8/SVneo Cells

The uninfected, LV-NC and LV-miR-137 groups of HTR-8/SVneo cells were plated at a density of 600-800 cells/well into a 6-well culture plate (Corning Incorporated) and cultured at 37°C in an atmosphere containing 5% CO2, with exchange of the culture medium every other day. The uniformly plated uninfected HTR-8/SVneo cells were cultured with IL-6 antibody (α-IL-6; 1:1,000; BioLegend, Inc.) supplementary medium at 37°C, with HTR-8/SVneo cells not treated with α-IL-6 as a control group. The LV-NC and LV-miR-137 HTR-8/SVneo cells were cultured with normal and HG medium. After 10 days, the medium was removed from each well, and the plate was washed with PBS. The cells were then fixed with 4% paraformaldehyde (Biotech Well, Shanghai, China) for 10 min. Following the fixation process, crystal violet hydrate solution (Sangong Biotech, Co., Ltd.) was added for cell staining for 30 min. Finally, images of each well were captured by a camera (E-M1 Mark II; Olympus Corporation;) and colonies were counted, with a colony defined as >15 cells.

In the text, the following abbreviations are used for morphological terms:

F1, F2, F3 = flagellomeres 1, 2, 3

MOD = anterior ocellar diameter

MS = malar space, the shortest distance between base of mandible and margin of compound eye

OOL = oculo-ocellar line, the shortest distance between lateral ocellus and compound eye

P = pedicel

PD = puncture diameter

POL = the shortest distance between posterior ocelli

T1–T3 = metasomal terga 1 to 3

vs. = versus

Photographs were taken with a Camera Olympus E-M1 Mark II with the Olympus Zuiko 60 mm objective and stacked with the software Helicon Focus (ver. 7.6). Further image processing was completed with Adobe Photoshop CS6.0.

Bee Morphology and Dietary Analysis

Morphological terminology follows MICHENER (2007) . The abbreviations A and T are used for antennal segments and metasomal terga, respectively. Specimens were measured from the vertical plane of the front of the head to the tip of the metasoma. Photographs were taken using an Olympus E-M1 Mark II with a 60 mm macro lens. Close-ups were taken with the addition of a Mitutoyo M Plan Apo 10X infinity corrected objective lens or a Lomo 3.7x objective lens in combination with an Olympus M.Zuiko 2x teleconverter lens, a 10 mm Kenko DG extension tube, and a Meike MK-P-AF3B 10 mm extension tube. Photographs were stacked using Zerene Stacker ver. 1.04 (Zerene Systems, USA) and plates were prepared in GNU Image Manipulation Program (GIMP) ver. 2.10. Post-processing of some images was made in Photoshop Elements (Adobe Systems, USA) in order to improve lighting to highlight specific characters.
Where available, pollen was removed from scopae of female Andrena and analysed by light microscopy in order to investigate their dietary preferences following the method of WOOD & ROBERTS (2018) (link). Dietary classification follows MÜLLER & KUHLMANN (2008) (link).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
