🔍 Recent Discoveries Highlight

The following findings are supported by recent academic research, with citations provided in MLA format.

Y-linked KDM5D is upregulated by mutant KRAS in male colorectal cancer, driving metastasis; deleting it reduces invasion in mice^{[1]Nguyen et al., Cancer Research, 2024}.
Loss of the Y chromosome (LOY) in bladder and other cancers impairs T-cell immunity but increases response to checkpoint inhibitors^{[2]Dumanski et al., Nature Communications, 2023}.
XIST lncRNA loss in females leads to X-chromosome reactivation and cancer stem cell expansion in breast and ovarian tumors^{[3]Ganesan et al., Oncogene, 2023}.
A 2024 AACR review synthesizes how Y chromosome loss alters tumor growth, immune evasion, and therapy response^{[4]Thompson and Brown, Cancer Research, 2024}.

📊 Interactive Model: Y-Chromosome Loss & Tumor–Immune Dynamics

Adjust sliders to simulate effects of Y-chromosome loss (LOY) and immune strength on tumor growth and immune response:

LOY Level: 0.50

Immune Strength: 1.00

Assumes LOY impairs immune killing rate linearly; tumor growth rate increases accordingly. Model based on differential equations inspired by cancer research^{[2]Dumanski et al., Nature Communications, 2023}.

show/hide Code & Model Info

// ODE model: T' = rT – k(1–LOY) I T, I' = constant immune strength
// T: tumor size, I: immune strength, r: tumor growth rate, k: killing coefficient
const r = 0.1, k = 0.2, dt=0.1;
function run(LOY, I){
  let T=1, dataT=[], dataI=[];
  for(let t=0;t<100;t++){
    T += (r*T - k*(1-LOY)*I*T)*dt;
    dataT.push({t, y:T});
    dataI.push({t, y:I});
  }
  return {tumor: dataT, immune: dataI};
}

🔬 Data Collection & Sampling in Cancer Research

Simulate how sampling affects estimates of Y chromosome loss (LOY) prevalence in a cancer population. Adjust sample size and iterations to see variability in results, as used in studies like those cited^{[2]^[4].}

Sample Size:

Iterations:

Simulates random sampling from a population with 30% LOY prevalence, using a binomial distribution to estimate variability.
