We propose that many cancer cell lines contain a minor subpopulation of stem cells that is enriched in a SP, can be maintained indefinitely in culture, and is crucial for their malignancy.
Nevertheless, in addition to the achievements in stem cell research, many challenges still need to be overcome for stem cells to have versatile application in clinics.
Therefore, the use of adult stem cells, which are multipotent or unipotent, can be at present a more achievable strategy.

What is the relapse rate of NPM1 mutated AML in complete remission after induction therapy?
5 answers
The relapse rate of NPM1-mutated AML in complete remission after induction therapy varies based on additional genetic mutations. Patients with NPM1-mutated AML and concurrent MDS-related gene mutations have shown a higher relapse rate and shorter progression-free survival compared to those without these mutations. However, the presence of secondary-type mutations (STM) in NPM1-mutated AML does not significantly impact overall survival or event-free survival. Additionally, the combination of mutations such as FLT3-ITD, DNMT3A, and TP53 can identify subgroups with adverse prognosis, affecting the relapse rates and overall survival of NPM1-mutated AML patients. Therefore, the relapse rate of NPM1-mutated AML in complete remission post-induction therapy is influenced by the specific genetic mutations present in the individual patient.
What molecular mechanisms are involved in the reprogramming of somatic cells?
10 answers
The reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) involves a complex interplay of molecular mechanisms that orchestrate changes in gene expression, chromatin structure, and cellular metabolism. Key transcription factors, such as OCT4, SOX2, KLF4, and c-MYC, initiate this process by establishing a pluripotency regulatory network. Single-cell transcriptomics have revealed that reprogramming follows diverging trajectories, with changes in chromatin accessibility at core pluripotency genes and the involvement of transcription factors linked to the trophectoderm lineage, indicating multiple routes to pluripotency. Epigenetic modifications play a crucial role, with enzymes like ALKBH5 and KDM6A modulating the reprogramming efficiency through demethylation activities that affect gene expression and metabolic patterns. Similarly, the DNA-modification enzymes Parp1 and Tet2 facilitate the early epigenetic reprogramming by modifying cytosine bases at pluripotent loci. The process also shares similarities with cancer initiation, where the ERas-Akt-FoxO1 signaling axis enhances reprogramming, highlighting the importance of signaling pathways. Moreover, the reprogramming efficiency is influenced by the cellular metabolic state, with autophagy playing a dual role mediated by mTORC1 signaling, and threonine catabolism by TDH being identified as a novel regulator. Environmental stress, such as hyperosmosis, can also enhance reprogramming by activating p38, which in turn reduces global DNA methylation levels and upregulates pluripotency genes. Chromatin and genome organization undergo significant alterations, with global decondensation and local reorganization supporting the activation of pluripotency-related genes and the silencing of lineage-specific genes. Additionally, the role of p53 as a barrier and p63 as an enabling factor for reprogramming further underscores the complexity of the molecular mechanisms involved, with distinct requirements for different combinations of reprogramming factors. In summary, the reprogramming of somatic cells to iPSCs is governed by a multifaceted network of transcriptional, epigenetic, signaling, and metabolic mechanisms, each contributing to the efficiency and outcome of the reprogramming process.
What does the FSH hormone do for ovulation?
4 answers
FSH (Follicle-Stimulating Hormone) plays a crucial role in ovulation by stimulating follicular growth and development in the ovaries. It acts as a major survival factor for antral follicles, promoting their growth and maturation. FSH induces the production and secretion of estrogen, which in turn stimulates the growth and maturation of ovarian follicles, ultimately leading to ovulation. Additionally, FSH activates more than 100 genes in granulosa cells, leading to important actions in the later stages of follicular development and maturation. The hormone's actions are transduced by the FSH receptor, triggering signaling pathways that drive the ovarian follicle towards ovulation. Overall, FSH's role in promoting follicular growth, maturation, and hormonal responses is essential for the ovulation process.
