A Review Of The Research On The Regulation Of Cell Apoptosis And Anti Mutation Effects By Active Ingredients Of Cistanche Tubulosa

Cistanche tubulosa is a perennial parasitic herbaceous plant belonging to the genus Cistanche in the family Liliaceae. It is known as the "desert ginseng" and is a traditional Chinese medicinal herb with a long history of clinical application. Its nature is sweet, salty, and warm, and it belongs to the kidney and colon meridians. It has the classic effects of tonifying kidney yang, nourishing essence and blood, moistening the intestines, and promoting bowel movements. Modern pharmacological research has confirmed that Cistanche tubulosa is rich in various bioactive components and has a wide range of pharmacological effects, such as antioxidant, anti-inflammatory, immune regulation, anti-tumor, anti-aging etc. Abnormal cell apoptosis and gene mutations are the core pathological mechanisms of aging, tumor development, and inflammatory disease progression in the body. Excessive abnormal cell proliferation, inhibition of apoptosis, and accumulation of gene damage can induce malignant transformation of cells, ultimately leading to the occurrence of various diseases. In recent years, scholars at home and abroad have conducted extensive basic research on the biological functions of active ingredients in Cistanche tubulosa, confirming that it can regulate the process of cell apoptosis and inhibit cell gene mutations through multiple pathways and targets, demonstrating great potential in disease prevention and adjuvant therapy.

Overview of the main active ingredients in Cistanche tubulosa

The medicinal value of Cistanche tubulosa lies in its rich secondary metabolites. Currently, over a hundred active ingredients have been isolated and identified from mainstream medicinal varieties such as desert Cistanche tubulosa, tubular Cistanche tubulosa, and salt-grown Cistanche tubulosa. Among them, the core components that exert cellular regulation and anti-mutation effects are mainly phenylethanolic glycosides, polysaccharides, and alkaloids. The synergistic effect of these three components constitutes the material basis for the pharmacological activity of Cistanche tubulosa.

Main Chemical Constituents of Cistanche tubulosa

Phenylethanolic glycosides (CPhGs) are the most representative characteristic active ingredients of Cistanche tubulosa, with the highest content and the most in-depth research. They mainly include monomeric compounds such as echinacoside, verbascoside, and Cistanche tubulosa glycoside. This type of ingredient has extremely strong biological activity and can penetrate the cell membrane to participate in cell signal transduction. It widely participates in physiological and pathological processes such as cell proliferation, apoptosis, oxidative stress, gene repair, etc. It is the core effective ingredient of Cistanche tubulosa in anti-tumor, anti-mutation, and cell protection. Research has shown that the content of phenylethanoid glycosides in both tubular and desert Cistanche tubulosa can reach over 20%, with the pharmacological activities of pineal glycoside and verbascoside being the most significant.

Phenylethanol glycoside is the main active component of Cistanche tubulosa

Cistanche polysaccharides are a class of water-soluble macromolecular active ingredients, mainly composed of monosaccharides such as glucose, fructose, and arabinose. They have antioxidant, immunomodulatory, neuroprotective, and apoptosis-regulating effects. It mainly works in the fields of anti-aging and organ protection by clearing intracellular reactive oxygen species, improving cellular oxidative stress status, maintaining cellular physiological homeostasis, reducing apoptosis, and gene mutations caused by oxidative damage.

Alkaloids are important active components of Cistanche tubulosa, with betaine and Cistanche alkaloids as the main representatives. Although their content is lower than that of phenylethanolic glycosides and polysaccharides, they can regulate cell metabolism, inhibit inflammation pathway activation, assist in regulating cell apoptosis, alleviate cell gene damage caused by external stimuli, and form pharmacological synergistic effects with other active ingredients. In addition, the components such as iridoids and lignans contained in Cistanche tubulosa also have certain cellular regulatory activities, but their mechanisms of action are not fully understood, and further in-depth research is needed.

The regulatory effect and mechanism of active ingredients in Cistanche tubulosa on cell apoptosis

Apoptosis is a programmed cell death process regulated by genes, which is the core mechanism for maintaining cellular homeostasis and eliminating abnormal cells in the body. Under normal physiological conditions, cell apoptosis is in a dynamic equilibrium. Insufficient apoptosis can lead to the accumulation of abnormal cells, uncontrolled proliferation, and the induction of tumors and proliferative diseases; Excessive apoptosis can cause damage to normal cells, tissue function decline, and trigger neurodegenerative diseases, organ damage, and other illnesses. The active ingredients of Cistanche tubulosa can exert bidirectional regulatory effects based on cell type and pathological status, inducing apoptosis of tumor cells and aging abnormal cells, while inhibiting excessive apoptosis of normal cells, achieving precise regulation of cellular homeostasis in the body.

Inducing abnormal cell apoptosis and inhibiting malignant cell proliferation

The core characteristic of tumor cells is the obstruction of apoptosis pathways and unlimited proliferation. The core active ingredients of Cistanche tubulosa can induce apoptosis in various tumor cells, inhibit tumor proliferation, invasion, and metastasis through multiple pathways such as activating the mitochondrial apoptosis pathway, regulating apoptosis-related gene expression, and blocking the cell cycle, and exhibit significant dose - and time-dependent effects.

Phenylethanolic glycosides are the core components that induce apoptosis in tumor cells, and their mechanism of action is mainly activated by mitochondrial-dependent pathways. Research has confirmed that phenylethanolic acid glycosides from Cistanche tubulosa can significantly upregulate the expression of pro-apoptotic proteins and genes such as Bax, Caspase-3, and Caspase-9, and downregulate the levels of anti-apoptotic proteins such as Bcl-2 and Bcl-xL, disrupting the balance of apoptotic proteins in tumor cells. During the activation of the mitochondrial pathway, phenylethanolic acid can reduce the mitochondrial membrane potential of tumor cells, promote the release of cytochrome C into the cytoplasm, activate downstream Caspase cascade reactions, and ultimately induce programmed cell death of tumor cells. Experimental studies have shown that after treatment with phenylethanolic glycosides from Cistanche tubulosa, the apoptosis rate of colorectal cancer cells can be increased from 2.5% to 27%, and the cell proliferation activity is significantly reduced. At the same time, these ingredients can block the G1/S phase cell cycle transition of tumor cells and block the division and proliferation of tumor cells by inhibiting PI3K/AKT, Raf/MEK/ERK, and other proliferation-promoting signal pathways, and have significant inhibitory effects on many tumor cells, such as liver cancer, lung cancer, breast cancer, ovarian cancer, and so on.

In addition, phenylethanolic acid can induce tumor cell apoptosis by regulating the tumor microenvironment and inhibiting angiogenesis. It can reduce the expression of matrix metalloproteinase MMP2 and vascular endothelial growth factor VEGF, inhibit tumor angiogenesis, cut off the nutritional supply of tumor cells, and block the migration and invasion pathways of tumor cells, thus suppressing the process of tumor metastasis. Research on non-small cell lung cancer has found that phenylethanolic acid glycosides from Cistanche tubulosa can inhibit abnormal activation of the AMPK signaling pathway, alleviate oxidative stress and inflammatory response in tumor cells, induce pyroptosis in tumor cells, and synergistically exert anticancer effects.

Inhibit excessive apoptosis of normal cells and exert cell protective effects

Under external damage stimuli such as oxidative stress, inflammation, ischemia, and hypoxia, normal cells undergo excessive apoptosis, leading to tissue and organ damage and functional decline. The active ingredients, such as polysaccharides from Cistanche tubulosa and phenylethanolic glycosides, can inhibit excessive apoptosis of normal cells and exert organ and cell protective effects through antioxidant, anti-inflammatory, and regulation of apoptosis pathways.

The cell protective effect of polysaccharides from Cistanche tubulosa is particularly prominent. It can activate the Nrf2/HO-1 antioxidant pathway, increase the activity of intracellular superoxide dismutase and glutathione peroxidase, eliminate excess reactive oxygen species, and reduce oxidative stress-induced cell apoptosis. In the D-galactose-induced aging mouse model, polysaccharides from Cistanche tubulosa can significantly upregulate the expression of the Bcl-2 gene in brain tissue, reduce the number of neuronal apoptosis, and improve neurological function damage. In the renal cell injury model, Cistanche tubulosa phenylethanolic acid can downregulate the expression of apoptosis-related proteins such as P53 and P21, upregulate Bcl-2 levels, inhibit excessive apoptosis of renal tubular epithelial cells, and alleviate renal tissue damage.

Meanwhile, the active ingredients of Cistanche tubulosa can reduce secondary cell apoptosis by inhibiting the activation of inflammatory pathways. The extensive infiltration of inflammatory factors can activate cell apoptosis signals, causing tissue damage. However, alkaloids from Cistanche tubulosa and phenylethanolic glycosides can inhibit the activation of TLR4 and NLRP3 inflammatory pathways, reduce the release of inflammatory factors such as tumor necrosis factor - α and interleukin, block the inflammatory-mediated chain reaction of cell apoptosis, and have good protective effects on liver cells, nerve cells, and myocardial cells.

The anti-mutagenic effect and molecular mechanism of active ingredients in Cistanche tubulosa

Gene mutations are important triggers for malignant transformation of cells, tumorigenesis, and aging of the body. External physical and chemical stimuli, as well as oxidative stress disorders within cells, can all lead to DNA strand breaks, base mutations, chromosomal abnormalities, and cause cellular dysfunction. The anti-mutagenic effect of active ingredients in Cistanche tubulosa mainly relies on four pathways: antioxidant damage, stable gene structure, activation of DNA repair pathways, and inhibition of mutant cell proliferation, to block gene mutations and subsequent pathological processes from the source.

Eliminate oxidative damage and reduce DNA mutation triggers

Excessive accumulation of reactive oxygen species within cells is a core endogenous factor that induces DNA oxidative damage and gene mutations. Reactive oxygen species can directly attack DNA bases and deoxyribose skeletons, causing base oxidation, DNA strand breaks, chromosomal aberrations, and ultimately leading to gene mutations. Cistanche polysaccharides and phenylethanolic glycosides have strong antioxidant activity, which can dual regulate the redox balance of the body: on the one hand, they directly eliminate excess reactive oxygen species, hydroxyl radicals and other oxidative mediators in cells, reducing the direct damage of oxidative substances to DNA; On the other hand, upregulating antioxidant enzyme activity enhances the endogenous antioxidant capacity of cells and continuously maintains cellular oxidative homeostasis.

Research has confirmed that the active ingredients of Cistanche tubulosa can significantly reduce the content of oxidative damage markers such as malondialdehyde in cells, reduce the accumulation of DNA oxidative bases, and avoid gene mutations mediated by oxidative stress. In the chemical mutagenesis model, the extract of Cistanche tubulosa can significantly reduce the rate of chromosomal aberrations and micronuclei in cells, effectively inhibit gene damage caused by chemical mutagens, and demonstrate good anti-mutagenic activity.

Stabilize gene expression and activate DNA repair pathways

P53 is a key tumor suppressor gene and DNA repair regulatory gene in the body, which can sense DNA damage, block the cell cycle, and initiate DNA repair. If the P53 gene is abnormally expressed or mutated, it can lead to damaged DNA that cannot be repaired and induce malignant transformation of cells. The active ingredients of Cistanche tubulosa can exert gene protection and repair effects by regulating the P53 signaling pathway. Research has found that phenylethanolic acid glycosides from Cistanche tubulosa can reduce the expression of phosphorylated P53 and P21 proteins in renal tissue cells, decrease the accumulation of DNA damage marker gamma H2AX, repair damaged DNA structures, and inhibit the accumulation of gene mutations.

Meanwhile, the active ingredients of Cistanche tubulosa can provide a time guarantee for DNA repair by regulating cell cycle checkpoints. It can block the abnormal proliferation of damaged cells, arrest them in the repair cycle, promote the activation of pathways such as base excision repair and nucleotide excision repair in the body, timely repair damaged genes, prevent the replication and transmission of mutant genes, and inhibit the process of cell mutation at the molecular level.
