[PMID: 40136693 PMCID: PMC11941520 DOI: 10.3390/cells14060444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2025] [Revised: 03/11/2025] [Accepted: 03/14/2025] [Indexed: 03/27/2025] Open
Abstract
Increasing evidence has suggested that dihydrolipoamide S-acetyltransferase (DLAT), a subunit of the pyruvate dehydrogenase complex, is crucial for pyruvate metabolism and the regulation of cell death. The excessive death of granulosa cells (GCs) hinders the progression of follicular growth. However, the relationship between DLAT and follicular growth is poorly understood. Here, we found that pyruvate significantly shortened the age of pubertal initiation in mice and promoted follicular growth by promoting the proliferation of GCs. In addition, pyruvate up-regulated the expression of DLAT and the high level of DLAT was observed in large follicles, which were associated with follicular growth. Mechanistically, DLAT increased the mRNA and protein levels of proliferation pathways such as PCNA and MCL1 to promote GC proliferation. Additionally, DLAT bound to CASP3 and CASP9 proteins to inhibit the apoptosis of GCs. Taken together, these results reveal a mechanism that pyruvate regulated DLAT to promote follicular growth, and DLAT represents a promising target that supports new strategies for improving the growth of follicles.

Berberine Inhibits Migration and Apoptosis of Rat Podocytes in Diabetic Nephropathy via the Novel lncRNA LOC102549726 Related Pathway. Phytother Res 2025; 39:1615-1631. [PMID: 39916312 DOI: 10.1002/ptr.8452] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 01/23/2025] [Accepted: 01/26/2025] [Indexed: 03/11/2025]
Abstract
BACKGROUND Diabetic nephropathy (DN) stands as one of the most severe complications of diabetes. Podocytes injury, particularly its attachment to the lateral glomerular basement membrane, serves as a crucial indicator of DN. Growing evidence suggests that berberine (BBR) can mitigate the onset and progression of DN. However, the molecular mechanisms through which BBR exerts its beneficial effects in the treatment of DN remain incompletely elucidated. PURPOSE To explore the underlying mechanisms by which BBR exerts its therapeutic effects in DN. METHODS High-throughput lncRNA sequencing on the renal cortex of both the DN model group and the normal SD group was performed to dig for differentially expressed lncRNAs. The expression of LOC102549726 was evaluated using qPCR. The biological functions of LOC102549726 were analyzed in podocyets and DN rats. The bioinformatics techniques, qPCR and WB were used to explore the potential molecular mechanisms. RESULTS We found that lncRNA LOC102549726 was highly expressed in renal cortex of DN rats and podocytes subjected to high glucose conditions. Silencing LOC102549726 inhibited migration and apoptosis of podocytes. Mechanistically, LOC102549726 was identified as a facilitator of the expression of EGF and forkhead box O1 (FOXO1). BBR, a known therapeutic agent for DN, exhibited the ability to diminish the level of LOC102549726, EGF and FOXO1 in both DN rats and podocytes. CONCLUSION Our findings suggested that BBR suppresses migration and apoptosis of podocytes in DN through targeting the LOC102549726/EGF/FOXO1 axis. This sheds light on a potential therapeutic avenue for mitigating the impact of DN on podocyte function.

The antisense lncRNA of TAB2 that prevents oxidative stress to enhance the follicular growth in mammals. Commun Biol 2024; 7:1246.

Abstract
LncRNAs are highly implicated in oxidative stress (OS) during the growth of mammalian follicles. TAK1 binding protein 2 gene (TAB2) has been suggested to involve in the normal apoptosis and proliferation of granulosa cells (GCs), the main supporting cells in ovarian follicles. In this study, we found that TAB2 increased the expressions of SOD1, P50, and P65 to suppress the OS, thereby inhibiting the apoptosis and promoting the proliferation in GCs. Notably, DNMTs appeared to mediate the expression of TAB2 without the changes of DNA methylation at TAB2's promoter. We identified an antisense lncRNA of TAB2, discovered that DNA methylation regulated the transcription of TAB2-AS in GCs, and found TAB2-AS medicated the follicular growth of ovaries in vivo. Mechanistically, the hypomethylation of the CpG site (-1759/-1760) activated the transcription of TAB2-AS, and the 1-155 nt and 156-241 nt of TAB2-AS were respectively complementary to 4368-4534 nt and 4215-4300 nt of TAB2's mRNA to increase the expression of TAB2. Moreover, TAB2-AS inhibited the OS and apoptosis of GCs, while promoted the proliferation of GCs to expedite the follicular growth, which was in line with that of TAB2. Collectively, these findings revealed the antisense lncRNA mechanism mediated by DNA methylation, and TAB2-AS might be the target to control OS during follicular growth in mammals.

[PMID: 39272993 PMCID: PMC11394089 DOI: 10.3390/cells13171421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2024] [Revised: 08/22/2024] [Accepted: 08/24/2024] [Indexed: 09/15/2024] Open
Abstract
Ovarian aging results in reproductive disorders and infertility in mammals. Previous studies have reported that the ferroptosis and autophagy caused by oxidative stress may lead to ovarian aging, but the mechanisms remain unclear. In this study, we compared the morphological characteristics between the aged and young ovaries of pigs and found that the aged ovaries were larger in size and showed more corpora lutea. TUNEL assay further showed that the apoptosis level of granulosa cells (GCs) was relatively higher in the aged ovaries than those in young ovaries, as well as the expressions of autophagy-associated genes, e.g., p62, ATG7, ATG5, and BECN1, but that the expressions of oxidative stress and aging-associated genes, e.g., SOD1, SIRT1, and SIRT6, were significantly lower. Furthermore, the RNA-seq, Western blotting, and immunofluorescence suggested that phospholipid phosphatase 3 (PLPP3) protein was significantly upregulated in the aged ovaries. PLPP3 was likely to decrease the expressions of SIRT1 and SIRT6 to accelerate cellular senescence of porcine GCs, inhibit the expressions of SOD1, CAT, FSP1, FTH1, and SLC7A11 to exacerbate oxidative stress and ferroptosis, and arouse autophagy to retard the follicular development. In addition, two SNPs of PLPP3 promoter were significantly associated with the age at puberty. g.155798586 (T/T) and g.155798718 (C/C) notably facilitated the mRNA and protein level of PLPP3. In conclusion, PLPP3 might aggravate the oxidative stress of GCs to accelerate ovarian aging, and two molecular markers of PLPP3 were identified for ovarian aging in pigs. This work not only contributes to investigations on mechanisms for ovarian aging but also provides valuable molecular markers to postpone ovarian aging in populations.

Abstract
Granulosa cells (GCs) are essential for follicular development, and long non-coding RNAs (LncRNAs) are known to support the maintenance of this process and hormone synthesis in mammals. Nevertheless, the regulatory roles of these lncRNAs within sheep follicular GCs remain largely unexplored. This study delved into the influence of a Loc105611671, on the proliferation and steroid hormone synthesis of sheep ovarian GCs and the associated target genes in vitro. Cell Counting Kit-8 (CCK-8) gain-of-function experiments indicated that overexpression of Loc105611671 significantly boosted GCs proliferation, along with estrogen (E2) and progesterone (P4) levels. Further mechanistic scrutiny revealed that Loc105611671 is primarily localized within the cytoplasm of ovarian granulosa cells and engages in molecular interplay with CDC42. This interaction results in the upregulation of CDC42 protein expression. Moreover, it was discerned that increased CDC42 levels contribute to augmented proliferation of follicular granulosa cells and the secretion of E2 and P4. Experiments involving co-transfection elucidated that the concurrent overexpression of CDC42 and Loc105611671 acted synergistically to potentiate these effects. These findings provide insights into the molecular underpinnings of fecundity in ovine species and may inform future strategies for enhancing reproductive outcomes.

Knockdown of DNMT1 Induces SLCO3A1 to Promote Follicular Growth by Enhancing the Proliferation of Granulosa Cells in Mammals. Int J Mol Sci 2024; 25:2468.

Abstract
In female mammals, the proliferation and apoptosis of granulosa cells (GCs) have been shown to determine the fate of follicles. DNA methyltransferases (DNMTs) and SLCO3A1 have been reported to be involved in the survival of GCs and follicular growth. However, the molecular mechanisms enabling DNMTs to regulate the expression of SLCO3A1 to participate in follicular growth are unclear. In this study, we found that the knockdown of DNMT1 enhanced the mRNA and protein levels of SLCO3A1 by regulating the chromatin accessibility probably. Moreover, SLCO3A1 upregulated the mRNA and protein levels of MCL1, PCNA, and STAR to promote the proliferation of GCs and facilitated cell cycle progression by increasing the mRNA and protein levels of CCNE1, CDK2, and CCND1, but it decreased apoptosis by downregulating the mRNA and protein levels of CASP3 and CASP8. Moreover, SLCO3A1 promoted the growth of porcine follicles and development of mice follicles. In conclusion, the knockdown of DNMT1 upregulated the mRNA and protein levels of SLCO3A1, thereby promoting the proliferation of GCs to facilitate the growth and development of ovarian follicles, and these results provide new insights into investigations of female reproductive diseases.
