Expression of alpha/beta hydrolase domain-containing protein 2 (ABHD2) in the mouse ovary. (a) Immunohistochemical (IHC) staining of a 1-month-old superovulated wild-type mouse ovary shows ABHD2 in the stromal cells (1) and in cells of the corpus luteum (CL) (2), while the protein is not present in the granulosa cells and oocytes of developing follicles, demarcated by staining of the surrounding smooth muscle layer (b) , and (3) Stromal cells of 1-week-old pre-pubertal mouse ovaries also display ABHD2 staining while (c) shows similar expression levels of Abhd2 before and after the first round of ovulation, as detected in 21- and 28-day-old mice ovaries. The expression levels increase after ovulation, as seen in ovaries at estrus and after superovulation. Samples ( n = 3 for each timepoint) were collected from 3-month-old females in proestrus and estrus and 1-month-old superovulated females. Expression levels measured by qPCR were normalized to the expression of ribosomal protein L19 ( Rpl19 ) and peptidylprolyl isomerase A ( Ppia ). Statistical significance was calculated using the unpaired t -test, and the significance of changes is indicated as follows: * p ≤ 0.05.

Article Snippet: The samples were analyzed by Western blotting, using a rabbit polyclonal anti-ABHD2 antibody (1:10,000 dilution, Proteintech Group, 14039-1-AP) and a peroxidase-conjugated anti-rabbit secondary antibody (1:15,000 dilution, Abcam, ab6721).

Generation of the Abhd2 KO mouse line. (a) Schematic picture of the Mus musculus Abhd2 gene with untranslated regions marked in gray. Deletion of exon 6 (in red) was performed by CRISPR/Cas9, targeting sequences in the surrounding introns. The sequences of the two sgRNAs are labeled in red and the PAM sequence in bold. (b) Genotyping of mice was performed using primers that bind outside the deleted sequence (arrows). The PCR product from a wild-type mouse (+/+) contains the exon 6 sequence while the full KO (-/-) lacks Abhd2 exon 6. Abhd2 +/– mice show a significant reduction of Abhd2 expression in both (c) qPCR and (d) western blot studies while the full KO Abhd2 –/– completely lacks expression of exon 6 and the protein. Expression levels detected by qPCR were normalized to the expression of ribosomal protein L19 ( Rpl19 ) and peptidylprolyl isomerase A ( Ppia ). Statistical significance was calculated using the unpaired t -test and the significance of changes is indicated as follows: ** p ≤ 0.01; **** p ≤ 0.0001. Abhd2 +/+ n = 4, Abhd2 +/– n = 4, and Abhd2 –/– n = 5. (e) The Abhd2 +/+ mouse ovary shows ABHD2 in the stromal cells surrounding the follicles. (f) No protein staining was detected in the Abhd2 –/– ovary.

Techniques:

Abhd2 –/– female ovulation and estrous cycle. (A) Spontaneous ovulation gave rise to similar numbers of eggs for all genotypes ( n = 3 for each genotype). (B) Abhd2 ablation caused significantly increased numbers of ovulated eggs after induction of superovulation, in both 1-month-old Abhd2 +/– ( n = 8) and Abhd2 –/– ( n = 7) females compared with Abhd2 +/+ mice ( n = 8). Statistical significance was calculated using the unpaired t -test, and the significance of changes is indicated as follows: * p ≤ 0.05; *** p ≤ 0.001. (C) Age-dependent decline in the number of eggs obtained after superovulation of 1-month-old females [data from panel (B) ], as well as 7- to 8-month-old ( Abhd2 +/+ n = 5, Abhd2 +/– n = 7, and Abhd2 –/– n = 6) and 15-month-old females ( n = 3 per genotype). Representative graphs of the estrous cycle of a (D) Abhd2 +/+ and (E) Abhd2 –/– female mouse where the Abhd2 KO female shows prolonged stages in estrus although displaying cyclical changes throughout the month. (F) The combined measurements of three mice of each genotype also showed a significantly altered distribution of days in the different estrous stages, in particular, the increased percentage of days in estrus and decreased percentage of days in proestrus of Abhd2 –/– females compared with Abhd2 +/+ mice ( n = 3 for each genotype).

Follicle count of the proestrus ovary. (a) Ovaries of 3.5-month-old Abhd2 +/– ( n = 3) and Abhd2 –/– ( n = 4) mice showed significantly lower numbers of early antral follicles, while the antral follicle number was increased compared with the Abhd2 +/+ females ( n = 4). (b) However, although hematoxylin staining of Abhd2 +/– and Abhd2 –/– ovaries displayed a higher number of atretic antral follicles compared with the wild-type ovaries, the total number of healthy follicles was similar between genotypes. (c) Representative images of Abhd2 +/+ , Abhd2 +/– , and Abhd2 –/– ovaries with apoptotic antral follicles marked by arrows. (d,e) TUNEL staining confirmed the follicles as apoptotic by labeling the granulosa cells of the atretic follicles.

a. Seven human ovarian serous adenocarcinoma cell lines and an immortalized human ovarian surface cell line HOSE/E7, all of which do not grow in soft agar, were used. Following transfection of the shRNA library, only OVCA420 cells formed colonies in soft agar. 43 colonies were successfully expanded. shRNAs were amplified by PCR and we reconstructed 69 different shRNA plasmids. Out of the 69 shRNAs in OVCA420 cells, 11 again generated colonies in soft agar. We then measured mRNA expression of these 11 genes using RT-PCR. Of the 11 shRNAs, shRNAs directed against ABHD2, CYB5R3 and ELAC2 suppressed target gene mRNA expression. b. Left: shRNA- ABHD2 transfected OVCA420 cell colony in soft agar. Black bar, 100 μm.

Figure Lengend Snippet: a. Differences in survival based on ABHD2 immunohistochemical scores (H-score) in HGSOC. b. Differences in survival based on ABHD2 mRNA expression in GSE9891 (n=285, mostly HGSOC) and GSE3149 (n=146, mostly HGSOC) datasets. Samples were divided into high (greater than the median value) and low (less than the median) expression cases. c. Analysis of HGSOC patients (n=36) from KOV-75 based on ABHD2 mRNA expression. d. Analysis of non-HGSOC patients (n=39) from KOV-75 based on ABHD2 mRNA expression. n.s., not significant.

Techniques: Immunohistochemical staining, Expressing

a. Representative data showing 7-ADD staining following 24 hour incubation with 10 μM cisplatin. b. The ratio of the 7-AAD negative live OVCA420 cells markedly increased following suppression of ABHD2 (sh1 and sh2) as compared to the control after 24 hour incubation with 10 μM cisplatin (n=3). c. Dose-response curves following incubation of OVCA420 cells with the indicated concentrations of cisplatin for 72 hours (n=6). d. Cisplatin IC50 values increased following suppression of ABHD2 in OVCA420 cells. e. Representative data showing 7-ADD staining following 24 hour incubation with 100 μM Carboplatin. f. The ratio of 7-AAD negative live OVCA420 cells markedly increased following suppression of ABHD2 (sh1 and sh2) as compared to the control following a 24 hour incubation with 100 μM carboplatin (n=3).
