TranscriptomicsFoxo1/3 depletion in granulosa cells reveals novel mechanisms controlling follicle growth and death and endocrine regulation of pituitary FSH.
The Foxo transcription factors regulate multiple cellular functions. Foxo1 and Foxo3 are highly expressed in granulosa cells of ovarian follicles. Selective depletion of the Foxo1 and Foxo3 genes in granulosa cells revealed a novel ovarian-pituitary endocrine feedback loop characterized by: 1) undet...

TranscriptomicsWild Type Tumor Repressor Protein 53 (TRP53) Promotes Ovarian Cancer Cell survival
Loss of Pten in the KrasG12D;Amhr2-Cre mutant mice leads to the transformation of ovarian surface epithelial (OSE) cells and rapid development of low-grade, invasive serous adenocarcinomas. Tumors occur with 100% penetrance and express elevated expression of wild type tumor repressor protein 53 (TRP...

TranscriptomicsFOXO1/3 and PTEN Depletion in Granulosa Cells Promotes Ovarian Granulosa Cell Tumor Development
The Forkhead Box, FOXO1 and FOXO3, transcription factors regulate multiple functions in mammalian cells. Selective inactivation of the Foxo1 and Foxo3 genes in murine ovarian granulosa cells severely impairs follicular development and apoptosis causing infertility, and as shown herein, granulosa cel...

TranscriptomicsERK1/2 in Ovarian Granulosa Cells are Essential for Female Fertility
A surge of luteinizing hormone (LH) from the pituitary gland triggers ovulation, oocyte maturation, and luteinization for successful reproduction in mammals. Since the signaling molecules RAS and ERK1/2 are activated by a LH surge in granulosa cells of preovulatory follicles, we disrupted Erk1/2 in ...

TranscriptomicsTumor repressor protein 53 and steroid hormones provide a new paradigm for ovarian cancer metastases
The functional status of the tumor repressor protein (TP53 or TRP53) is a defining feature of ovarian cancer. Mutant or null alleles of TP53 are expressed in greater than 90% of all high-grade serous adenocarcinomas. Wild type TP53 is elevated in low-grade serous adenocarcinomas in women and in our ...

TranscriptomicsEither Kras activation or Pten loss similarly enhance the dominant-stable CTNNB1-induced genetic program to promote granulosa cell tumor development in ovary and testis
Stable activation of the WNT signaling effector beta-catenin (CTNNB1(ex3) in ovarian granulosa cells results in the formation of premalignant lesions that develop into granulosa cell tumors (GCTs) spontaneously later in life. Loss of the tumor suppressor gene Pten accelerates GCT formation in the CT...

TranscriptomicsGENE EXPRESSION ALTERATIONS IN ADULT UTP14b (jsd) MICE BY CONDITIONAL KNOCKOUT OF ANDROGEN RECEPTOR IN SERTOLI CELLS
Spermatogenesis is dependent primarily on testosterone action on the Sertoli cells. Although the identification of testosterone-regulated target genes in Sertoli cells has been approached using microarray analysis to compare gene expression in mice with androgen receptor (AR) elimination in the Ser...

ProteomicscTAGE5 is essential for adipogenesis and adipose tissue development
White adipocytes serve as primary energy reservoirs and their malfunction is linked to different metabolic disorders, yet the mechanisms underlying cellular specialization, a critical step during adipogenesis remain unknown. Here, we reveal the indispensable role of cutaneous T cell lymphoma-associa...

ProteomicsCAF-1 promotes HIV-1 latency by leading the formation of phase-separated suppressive nuclear bodies
HIV-1 latency is a major obstacle to achieve a functional cure for AIDS. To eradicate the viral reservoir, one of the strategies is to specifically reactivate HIV-1-infected cells and followed by elimination with potent immune surveillance. However, present latency-reversing agents (LRAs) are quite ...
