TGF-β1 is a member of the transforming growth factor β (TGF-β) family. The transforming growth factor-β family of polypeptides are involved in the regulation of cellular processes, including cell division, differentiation, motility, adhesion and death. TGF-β1 positively and negatively regulates many other growth factors. It inhibits the secretion and activity of many other cytokines including interferon-γ, tumor necrosis factor-α and various interleukins. It can also decrease the expression levels of cytokine receptors. Meanwhile, TGF-β1 also increases the expression of certain cytokines in T cells and promotes their proliferation, particularly if the cells are immature. TGF-β1 also inhibits proliferation and stimulates apoptosis of B cells, and plays a role in controlling the expression of antibody, transferrin and MHC class II proteins on immature and mature B cells. As for myeloid cells, TGF-β1can inhibit their proliferation and prevent their production of reactive oxygen and nitrogen intermediates. However, as with other cell types, TGF-β1 also has the opposite effect on cells of myeloid origin. TGF-β1 is a multifunctional protein that controls proliferation, differentiation and other functions in many cell types. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts. Once cells lose their sensitivity to TGF-β1-mediated growth inhibition, autocrine TGF-β signaling can promote tumorigenesis. Elevated levels of TGF-β1 are often observed in advanced carcinomas, and have been correlated with increased tumor invasiveness and disease progression.

TGF-β1 是轉化生長因子 β (TGF-β) 家族的成員。轉化生長因子-β 多肽家族參與細胞過程的調節，包括細胞分裂、分化、運動、黏附和死亡。 TGF-β1 對許多其他生長因子具有正向和負向調節作用。它抑制許多其他細胞因子的分泌和活性，包括幹擾素-γ、腫瘤壞死因子-α和各種白細胞介素。它還可以降低細胞激素受體的表達水平。同時，TGF-β1 也會增加 T 細胞中某些細胞激素的表達並促進其增殖，特別是在細胞未成熟的情況下。 TGF-β1也抑制B細胞增殖並刺激B細胞凋亡，並在控制未成熟和成熟B細胞上抗體、轉鐵蛋白和MHC II類蛋白的表達方面發揮作用。對於骨髓細胞，TGF-β1可以抑制其增殖並阻止其產生活性氧和氮中間體。然而，與其他細胞類型一樣，TGF-β1 對骨髓來源的細胞也有相反的作用。 TGF-β1 是一種多功能蛋白，可控制多種細胞類型的增殖、分化和其他功能。它在骨重塑中發揮重要作用，因為它是成骨細胞骨形成的有效刺激劑，引起定型成骨細胞的趨化性、增殖和分化。一旦細胞失去對 TGF-β1 介導的生長​​抑制的敏感性，自分泌 TGF-β 訊號傳導就會促進腫瘤發生。在晚期癌症中經常觀察到 TGF-β1 水平升高，並且與腫瘤侵襲性增加和疾病進展有關。

FGF21 是纖維母細胞生長因子 (FGF) 家族的成員。此家族的蛋白具有廣泛的促有絲分裂和細胞存活活性，參與多種生物過程，如血管生成、傷口癒合、神經發育、腫瘤發生和發展等。大多數 FGF（FGF3-8、10、15、17-19、21-23）在 N 端具有典型的訊號序列分泌蛋白。其中，纖維母細胞生長因子21（FGF 21）在肝臟中特異性表達，透過脂肪組織和胰臟範圍降低血糖和三酸甘油酯。胰高血糖素可改善胰島 B 細胞的功能，進而預防飲食引起的肥胖和胰島素抗性。此外，FGF21也被證明是一種主要的血清素內源性調節因子，在禁食和酮症中發揮關鍵作用。

Annexin V是一種鈣離子依賴性磷脂結合蛋白，分子量為35~36KDa，能以高親和力與磷脂醯絲胺酸PS特異性結合。在正常細胞中，磷脂醯絲胺酸僅分佈在細胞膜脂質雙層的內側。在細胞凋亡的早期，膜上的磷脂醯絲胺酸（PS）從脂膜的內側轉向外側。作為一種磷脂結合蛋白，Annexin V 與磷脂醯絲胺酸具有高親和力。它透過暴露在細胞外部的磷脂酰絲氨酸與細胞凋亡早期的細胞膜結合。因此，Annexin V是檢測早期細胞凋亡的敏感指標。

腫瘤壞死因子配體超家族成員11，又稱為核因子受體活化劑kappa-B配體、骨保護素配體、TNFSF11、RANKL、TRANCE、OPGL和CD254，在多種細胞中表達，包括成骨細胞、纖維母細胞、活化的T細胞和骨髓基質細胞可以與誘餌受體 OPG 相互作用。TNFSF11參與許多基本生物學過程，例如調節T細胞和樹突狀細胞之間的相互作用、調節T細胞依賴性免疫反應以及增強惡性腫瘤體液高鈣血症中的骨吸收。TNFSF11也增強了樹突細胞刺激初始T細胞增生的能力。
