Because the phenotypes of these two regimens were identical, data from both regimens were combined for analysis as specified in Figure legends.


Rats were euthanized on day 5 as noted in Regimen 1. Protein lysates were extracted from primary Sertoli cells or testes using IP lysis buffer [50 mM Tris, 0. Equal amount of protein lysate were resolved by SDS-PAGE and transferred to nitrocellulose membrane Bio-Rad for immunoblot analysis with the ACTION ACTINA MONTANA E 300G primary and secondary antibody Table S1 as described [ 41 ]. Target proteins were visualized by enhanced chemiluminescence [ 42 ].

In brief, the cross-sections were deparaffinized, rehydrated, and then subjected to antigen retrieval. Positive immunoreactivity was visualized by using aminoethyl carbazole AEC with kits from Life Technologies, which appeared as reddish-brown precipitates in IHC.


Negative controls using the same concentration of normal mouse IgG to substitute the primary antibody or the omission of secondary antibody were also included in our experiments. All sections of testes or Sertoli cells within an experimental group were processed simultaneously in a single experimental session to eliminate intraexperimental variations and each experiment was repeated using at least 3 different rat testes or Sertoli cell preparations.

Sertoli cells were also processed but incubated with normal IgG of the corresponding animal species by substituting the primary antibody or the omission of secondary antibody, which served as negative controls. ACTION ACTINA MONTANA E 300G were included in each experimental session, which yielded no detectable staining, confirming the immunofluorescent staining for a specific target protein was specific.

Rats received no treatment served as negative controls. Sigma Aldrich, St. Louis, MO.

After 30 min, rats were euthanized by CO 2 asphyxiation. Testes were removed immediately and snap-frozen in liquid nitrogen. To yield semi-quantitative data for the assessment of BTB integrity, the distance D traveled by the biotin D Biotin from the basement membrane in the seminiferous tubule vs. For oblique sections ACTION ACTINA MONTANA E 300G tubules, D Radius was obtained using the average of the shortest and the longest distance from the basement membrane.

This experiment was repeated with 4 independent experiments using different cell preparations. GAPDH was used as an internal control for normalization.

The specificity of the fluorescent signal was verified by both melting curve analysis and gel electrophoresis. For in vitro experiments that assessed the effects of overexpression of F5-peptide on target protein distribution in Sertoli cells at the cell-cell interface, at least cells from independent experiments were randomly selected from each group and examined as earlier described [ 46 ].

In brief, fluorescence intensity of a target protein e.

To assess changes in protein distribution, the relative fluorescence intensity of a target protein e. Fluorescence intensity of each target protein in the seminiferous epithelium of testes from at least 3 different rats following in vivo overexpression was quantified using ImageJ ACTION ACTINA MONTANA E 300G.

To assess the effects of F5-peptide overexpression on the integrity of the BTB, approximately 50 tubules from 6 rats were randomly selected from each group, including the positive and negative controls, and examined. Using frozen sections of testes and DAPI staining, the criteria to assess abnormality in tubules following overexpression of F5-peptide in testes were: However, due to the limited resolution using frozen sections, other apparently normal testes using frozen sections that had defects in spermatid and phagosome transport were further examined and demonstrated by histological ACTION ACTINA MONTANA E 300G using paraffin sections following hematoxylin and eosin staining as described [ 41 ].

As such, defects in spermatid and phagosome transport were not scored and included in analysis using frozen sections. Two regimens were used in this ACTION ACTINA MONTANA E 300G.

Because phenotypes using these two regimens were similar, data were pooled for analysis. For studies using Sertoli cell cultures, triplicate coverslips, or dishes, were used. In brief, biologically active.
