Turkey Tail mushrooms and FOS. Anyone else here use these?

I have been taking Turkey Tail Mushroom tea or capsules, along with Lion’s Mane’s mushroom tea or capsules and FOS for 4 years now. For the last few visits to my urologist, he has told me that he is surprised how well I am doing. When I first started seeing him, I was diagnosed with Stage 3-C, advanced and aggressive prostate cancer with a PSA of 54.0. My Gleason score was 8.
My search of the literature led me to taking FOS and Turkey Tail mushrooms since October, 2021. I added Lion’s Mane mushrooms to my daily routine a bit later. I take Turkey Tail mushrooms I have collected myself as well as commercially available capsules and mycelium powder. Cancer stem cells (CSC) promote metastasis, something that we all hope to avoid. Turkey Tail mushroom and specifically the polysaccharides within the mushroom are credited with combating the cancer stem cells. I attribute my lack of progression of my cancer to my Intensity Modulated Radiation Therapy aka IMRT, my one year of ADT, and to the supplements that I take daily.

Below, I have quoted from four peer reviewed articles without editorializing though I have bolded some of the most relevant passages.
An additional note, Turkey Tail mushrooms are now the subject of a clinical trial at the Mayo Clinic in pre-operative breast cancer patients. It has also been reported favorably for patients with colorectal cancer and a few other solid organ cancers.

The following acronyms are found in the quotes below.
A mucinphila the commensal intestinal mucin-degrading bacterium Akkermansia muciniphila

FOS FructooligoSaccharide or oligofructose

Advanced prostate cancer patients on androgen deprivation therapy have altered gut microbiota composition, with an accumulation of bacterial species that can synthesize dehydroepiandrosterone (DHEA) and testosterone from pregnenolone [through 17a-hydroxylase/17,20-desmo lase (CYP17A1)– like activity]. The presence of these species enhances tumor growth and progression to castration-resistant prostate cancer (CRPC)(1).
We have carefully examined a total of 24 the up-to-date available dietary intervention studies in search for evidence and strategies to increase A. muciniphila, a beneficial member of gut microbiota in the gut. Available evidence from animal studies showed that viable A.muciniphila or prebiotics (FOS) was able to consistently promote A. muciniphila abundance in the gut, suggesting a great potential for future development of dietary intervention approaches using viable bacterium or FOS for increasing gut A. muciniphila..(2)
Here, we demonstrated that the polysaccharopeptide (PSP) extracted from Turkey tail (known as Coriolus versicolor [aka Trametes versicolor] or Yun-zhi) targets prostate CSCs in vitro and suppresses tumor formation in vivo. Treatment of prostate cancer cell line PC-3 with PSP led to the down-regulation of CSC markers (CD133 and CD44) in a time and dose-dependent manner. Meanwhile, formation of prostasphere, a major property of prostate CSCs, was completely suppressed in PC-3 cells in the presence of PSP. Furthermore,PSP pre-treatment significantly suppressed tumor initiation of PC-3 cells in immunocompromised mice, suggesting that PSP suppresses the tumorigenicity of the PC-3 cells. More importantly, oral feeding of transgenic mice (TgMAP) that spontaneously develop prostate tumor with PSP was found to completely inhibit prostate tumor formation. Our findings support that PSP may be a potent chemo-preventive agent against prostate cancer, possibly through targeting of the prostate CSC population. (3)
Since ancient times, mushrooms have been considered valuable allies of human wellbeing both from a dietary and medicinal point of view. Their essential role in several traditional medicines is explained today by the discovery of the plethora of biomolecules that have shown proven efficacy for treating various diseases, including cancer. Numerous studies have already been conducted to explore the antitumoural properties of mushroom extracts against cancer. Still,very few have reported the anticancer properties of mushroom polysaccharides and mycochemicals against the specific population of cancer stem cells (CSCs). In this context, _-glucans are relevant in modulating immunological surveillance against this subpopulation of cancer cells within tumours.(4)
In fact, as reported in this review, mushrooms are an abundant source of mycochemicals that may intervene in several pathways involved in the induction of embryonic characteristics specific to CSCs, either alone or in synergy with conventional drug therapies.(4)
